--- sidebar_position: 4 --- # Running Many Gateways at Once Operate multiple [profiles](./profiles.md) — each with its own bot tokens, sessions, and memory — as managed services on a single machine. This page covers the operational concerns: starting them all together, viewing logs across profiles, preventing the host from sleeping, and recovering from common launchd/systemd quirks. If you only run one Hermes agent, you don't need this page — see [Profiles](./profiles.md) for the basics. And if your instances live on *different* machines that one desktop app should reach simultaneously, see [Connecting Desktop to Many Hermes Instances](./multi-connection-desktop.md). ## When to use this You want this setup when you have two or more Hermes agents that should all be online at the same time. Common reasons: - A personal assistant on one Telegram bot and a coding agent on another - One agent per family member or one per Slack workspace - Sandbox + production instances of the same configuration - A research agent + a writing agent + a cron-driven bot — each with isolated memory and skills Every profile already gets its own per-platform supervisor entry: a LaunchAgent (`ai.hermes.gateway-.plist`), a systemd user service (`hermes-gateway-.service`), a systemd **system** service when installed with `sudo hermes gateway install --system` (runs as the invoking user via `User=`), a Windows Scheduled Task, or an s6/Docker service — and the Desktop app spawns its own per-profile `hermes serve` backend. This guide adds the patterns for managing them collectively. ## Quick start ```bash # Create profiles (once) hermes profile create coder hermes profile create personal-bot hermes profile create research # Configure each coder setup personal-bot setup research setup # Install each gateway as a managed service coder gateway install personal-bot gateway install research gateway install # Start them all coder gateway start personal-bot gateway start research gateway start ``` That's it — three independent agents, each on its own process, restarting automatically on crash and on user login. ## Alternative: one gateway for all profiles (multiplexing) The model above runs **one process per profile**. The alternative is a **single multiplexing gateway**: one gateway process — whichever profile launched it — becomes the sole inbound process and serves messages for *every* profile on the box. The default profile's lifecycle verbs target that process. Named profiles can stop or restart just their own bots without stopping the host: - `hermes -p gateway run` while it is live **attaches** instead of starting a second process: it prints the host gateway's PID and served set and exits 0. If `` is not served yet, it asks the host gateway to re-scan `profiles/` and attaches once the answer includes it; it refuses (non-zero) only when the host gateway cannot be made to serve it. - `hermes gateway start --all` / `restart --all` mean *the one host multiplexer*. They never sweep every gateway process on the box; a profile that still runs its own gateway is reported, never killed, with the `hermes gateway migrate --multiplex` one-liner. - `hermes gateway run --replace` takes over the process **serving this profile**, whichever profile launched it. When the host owner is another profile's standalone gateway (an unmigrated per-profile fleet) it never serves this profile, so `--replace` starts beside it exactly as a plain `run` does, instead of refusing and respawn-storming under the supervisor. An older Hermes wrote a systemd drop-in (`hermes-gateway.service.d/20-replace.conf`) that forced `--replace` onto the unit; `hermes update` / `hermes gateway restart` now remove that file. `hermes gateway run --force` starts a separate gateway without asking the host process at all (the escape hatch when it is wedged or answering wrongly). - Under a service supervisor the attach exits 75, not 0 — systemd, s6 and launchd all restart a 75 after a short delay, so the unit keeps retrying and takes over by itself the moment the host process goes away. - Two units started at once can both see no host process yet; the host lock decides which one runs, and the loser exits 75 and attaches on the retry. `--replace` does not skip that check (every generated unit carries it), only `--force` does. Multiplexing is **on by default** (`gateway.multiplex_profiles` defaults to `true`), with one safety rule: an *unset* flag is a request the default gateway settles at boot, never a verdict. Each start it runs the same preflight as [`hermes gateway migrate --multiplex`](#migrating-from-per-profile-gateways) and multiplexes only when the fold would have been safe — two or more profiles, no secondary still running its own gateway (live process or installed service, or under s6 a per-profile slot that is actually *up*), no duplicate bot credential, and no port-binding platform without a `/p//` ingress. **Unset means on**: when nothing blocks, the gateway multiplexes and writes `gateway.multiplex_profiles: true` into the default profile's `config.yaml` (comments preserved) so the file says what the runtime does. Otherwise it comes up serving the default profile only and says so **loudly** on a host with other profiles: a boxed warning at gateway start naming the profiles that are not served, the blocker, and the fix; the same box in the `hermes update` summary and `hermes gateway status`; a banner in the dashboard (`/api/status` carries `multiplex_standalone_reason`). A single-profile install is not warned — there is nothing to serve. Nothing is written on a refusal. An **explicit** `true` bypasses migration preflight, except for a launching profile that opts out with `gateway.standalone: true`: - `gateway.multiplex_profiles: true` (what the migration writes) multiplexes regardless of the preflight — you, or the migration, made the call. - `gateway.multiplex_profiles` has **one valid value right now: `true`**, and it is written for you. An unset key resolves on and is made explicit in the default profile's `config.yaml`. `false` is **retired**: the gateway rewrites it to `true` in place and prints a one-time boxed notice at that start and in the next `hermes update` summary — never a silent flip. A per-profile gateway is `gateway.standalone: true` in that profile's own config (a temporary shim, not a supported topology) or `--force` for the boundary cases below. - `GATEWAY_MULTIPLEX_PROFILES` in the process environment overrides the unset-key decision the same way an explicit `true` does. - `gateway.standalone: true` in a **named** profile's own `config.yaml` (`profiles//config.yaml`) is a **temporary compatibility shim** (see [below](#temporary-gatewaystandalone-true)): the host gateway does not serve that profile, and the profile runs its own gateway without `--force`. Its gateway serves only itself, even if `multiplex_profiles: true` is also set (see [No new per-profile gateways](#no-new-per-profile-gateways)). Set on the default profile it is ignored with a warning — the default profile is the host gateway. There is no environment variable for this key. Other processes (`hermes -p gateway start`, the dashboard, `hermes gateway migrate`) never guess how an unset flag was settled: they read the running default gateway's `served_profiles` record, and fall back to the explicit flag only when no gateway runs. ### When to prefer multiplexing - A container/VPS deployment where N supervisor units, N ports, and N PID files are a burden. - Many low-traffic profiles that don't each justify a full process. - You want a single thing to start, monitor, and restart. One-process-per-profile is no longer a topology to *choose* implicitly: a named profile's `gateway install` / `gateway start` refuses without `--force` (see [No new per-profile gateways](#no-new-per-profile-gateways)). A profile that still needs its own gateway while a multiplexing gap is open can set the temporary `gateway.standalone: true` in its own `config.yaml`; where a real boundary blocks the fold — a fleet split across UNIX users, or a `HERMES_HOME` outside `/profiles/` — every profile keeps `--force` as its path. ### Pinning the flag With the flag unset, the default gateway decides at each boot (above). To pin it, set it on the profile whose gateway runs as the host process (usually the **default profile**) and restart its gateway — `true` forces multiplexing even where the boot preflight would have held back (`false` is retired and ignored): ```bash hermes config set gateway.multiplex_profiles true hermes gateway restart ``` Equivalently, in the default profile's `~/.hermes/config.yaml`: ```yaml gateway: multiplex_profiles: true ``` (The flag is also accepted as a top-level `multiplex_profiles: true` for convenience.) When multiplexing, the default gateway enumerates every profile, brings up each profile's enabled platforms under that profile's own credentials, and routes each inbound message to the profile it belongs to. Each turn resolves the routed profile's config, skills, memory, SOUL, **and provider keys** — credentials are never shared across profiles. The host automatically serves unparked secondary profiles. Use `gateway start` on a parked profile to bring it back online. ### Stopping one profile without stopping the host For a named profile served by the host multiplexer: ```bash hermes -p coder gateway stop # park coder; other profiles keep running hermes -p coder gateway start # unpark coder and serve it again hermes -p coder gateway restart # reconnect coder with its current configuration ``` `stop` writes `gateway.parked` in the profile home before asking the host to stop that profile's adapters and exclude its cron jobs from subsequent ticks. The marker persists across host restarts. Its contents are ignored; an empty file is sufficient. Provisioning can pre-create `/coder/gateway.parked` so an installed profile stays offline. Parking does not delete the profile, its sessions, or its scheduled jobs. `start` removes the marker, then asks a running host to serve the profile. Without a running host it removes the marker and follows the normal start path; start the host from the default profile if prompted. `restart` unserves and serves the profile without writing a parked marker, re-reading its config. On a **parked** profile with no live per-profile gateway, `restart` behaves as `start`: it removes the marker and hot-serves the profile (a gateway started with `--force` beside the marker keeps its own restart instead). These operations do not terminate work already dispatched by a cron tick. The host also rescans every 30 seconds: adding the marker by hand unserves the profile; removing it by hand makes it eligible again. If the control socket does not confirm the request, the CLI says so and the next rescan applies the marker state. Adapter teardown or connection can take additional time. `hermes -p coder gateway status` reports `parked (hermes -p coder gateway start)` while the marker exists. The launch profile cannot be unserved. The default profile's marker is ignored with a warning; its lifecycle verbs and the `--all` variants retain their whole-host behavior. A separately running `--force` gateway retains its own process lifecycle. The dashboard and Desktop **Stop** / **Start** buttons for a served profile do the same thing: Stop parks it (`/api/gateway/stop?profile=coder` spawns `hermes -p coder gateway stop`), Start unparks it while a host gateway is live, and `/api/status` lists `parked_profiles`. Start on a named profile that is *not* parked still answers `409` — it would need a gateway of its own. #### Parked vs `gateway.standalone: true` The two never apply to the same profile at the same time, and neither one implies the other: | Profile | Host serves it | `-p X gateway stop` | `-p X gateway start` | |---|---|---|---| | Served (default case) | yes | parks it (marker + `unserve-profile`) | already served | | Parked (`gateway.parked` exists) | no, until unparked | already parked | unparks (marker removed + `serve-profile`) | | Standalone (`gateway.standalone: true`) | never | stops **its own** gateway process; writes no marker | starts its own gateway | `gateway.standalone` wins: the host never writes `gateway.parked` for a standalone profile and never serves it, parked or not, so `stop` and `start` on that profile keep their per-process meaning. Parking is the multiplex-native way to take one profile offline — it is what closes the "per-profile stop/restart" gap the [temporary shim](#temporary-gatewaystandalone-true) was kept open for. ### No new per-profile gateways By default, one host gateway serves every profile, and a named profile does not get a gateway of its own. Without the opt-out below, `hermes -p coder gateway install` (or `start`, `run`, and the service step of `hermes -p coder setup`) refuses with exit 78 whether or not a host gateway is running right now: ``` ❌ Profile 'coder' does not get a gateway of its own. Exactly one gateway per host is the inbound process for every profile. Starting a separate gateway for this profile would double-bind its platforms (two pollers on one bot token, port conflicts). Install or start the host gateway from the default profile; it serves this one too: hermes gateway install Or fold an existing per-profile fleet onto one host gateway: hermes gateway migrate --multiplex A separate per-profile gateway (for a fleet split across UNIX users or a HERMES_HOME outside profiles/) needs --force: hermes -p coder gateway install --force Temporary compatibility path while multiplexing gaps are closed: set gateway.standalone: true in profiles/coder/config.yaml, then wait for the host gateway to rescan (<=30s) or send its rescan-profiles control verb. (gateway.standalone is a temporary compatibility shim while multiplexing gaps are fixed; it will be removed once they are — plan to fold this profile with `hermes gateway migrate --multiplex`.) ``` When the host gateway is already running and serves the profile, the first line reads `The host gateway already serves profile 'coder'.` with the owner's PID and served set, and the pointer is `hermes -p default gateway restart`. The dashboard's **Start** button for a named profile returns the same refusal. ### Temporary: `gateway.standalone: true` :::warning Temporary backwards compatibility, not a topology we keep Multiplex-only is the direction: one gateway per host serves every profile. The switch landed before every gap was closed — the WhatsApp bridge and relay on secondary profiles, and dashboard scoping are the open ones; per-profile stop/start/restart is closed by [parking](#stopping-one-profile-without-stopping-the-host) — and fleets that relied on per-profile gateways lost them overnight. `gateway.standalone: true` exists so those fleets keep working **while those gaps are fixed**. It will be removed once they are, with a release-notes notice ahead of time; every surface that prints it says so. Do not build new setups on it: if you are starting fresh, run the host multiplexer. If a gap blocks you today, set the key, and file or upvote the issue for the gap so we can remove the shim sooner. ::: Set `gateway.standalone: true` in the profile's own `config.yaml`: ```yaml # profiles/coder/config.yaml gateway: standalone: true ``` The host gateway then does not serve the profile, and the boot log records `profile 'coder' is standalone (gateway.standalone: true); not served by this gateway`. `hermes -p coder gateway install|start|run` works without `--force`. If the running host still lists the profile in its served set, the command refuses until it rescans: wait for the next rescan (at most 30 seconds under normal operation), or send the `rescan-profiles` control verb to the host gateway. No host restart is required. Removing the key makes the profile eligible for the host again. While the profile's own gateway is live, the host skips adding it and logs that it must be stopped first. Stop that gateway; the host takes the profile on its next rescan. A standalone profile's adapters, cron, webhook ingress and Kanban notifications run only while its own gateway runs, not under the host multiplexer or `hermes serve`. Point webhook clients at the standalone gateway's own listener; the host's `/p//` ingress no longer serves it. That listener resolves its port from the profile's own `.env` or `config.yaml`, so when both it and the host gateway enable the API server or webhook ingress, give the profile its own `API_SERVER_PORT` / `WEBHOOK_PORT`; two gateways left on the defaults both try to bind them. The cron destination picker still lists standalone profiles as `bot-chat:` targets, but the host cannot deliver to those targets. `hermes -p coder gateway status` prints `standalone by config (gateway.standalone: true)` before the profile's own gateway state, and `hermes gateway status` (default) lists it as `standalone by config: coder` after the served set. `hermes gateway migrate --multiplex` leaves the profile alone and prints it as `Standalone by config (gateway.standalone: true), left alone`. The WhatsApp bridge and relay run in the profile's own gateway, as in any standalone gateway. `--force` is not the path for this shim; it remains the escape for the two boundary cases the refusal names (a fleet split across UNIX users, a `HERMES_HOME` outside `profiles/`): it installs a real per-profile service, and that service (its `ExecStart` carries no `--force`) keeps starting normally afterwards. ### What changes when multiplexing is on Multiplexing changes how a few things behave. None of these apply to a profile that opts out with `gateway.standalone: true` or runs a separate `--force` gateway on a blocked host. #### 1. Secondary profiles must not start their own gateway With a multiplexer running, a named profile's `gateway run` attaches to it; `gateway install` refuses to create another process (exit code 78). The CLI refuses before touching a service manager, preventing a permanently failed systemd unit or a launchd respawn loop. Use the per-profile `stop`, `start`, and `restart` commands above to manage a satellite inside the host. `hermes gateway stop` on the default profile still takes every served profile offline. The dashboard and Desktop app follow the CLI: for a served profile the "Stop" action parks it and "Start" unparks it (see above); "Start" on an unparked named profile answers `409` with the same explanation (rendered as an inline notice on the System page). "Restart" restarts the multiplexer (the process that actually serves the profile) instead of spawning a `-p coder gateway restart` that could only fail. Because that restart reconnects every bot on the device, both apps first ask *"Restart the shared gateway? All bots on this device reconnect: default, coder, research"* (the list is the running gateway's `served_profiles`) and report *"Shared gateway restarted (3 bots)"* when it completes. A standalone profile keeps the plain restart. `/api/status?profile=coder` carries the same list as `gateway_shared_with` (null for a standalone gateway). "Served" is read from the running gateway's own record (`served_profiles` in the default home's `gateway_state.json`), so it stays correct when the multiplexer was enabled only through `GATEWAY_MULTIPLEX_PROFILES` in the default profile's environment, or when profiles were added after the gateway started. The setup flows follow the same rule: `hermes -p coder setup gateway`, `hermes -p coder setup`, `hermes -p coder gateway setup` and `hermes -p coder import` configure the profile's bots but skip the "install the gateway background service" step for a served profile, printing *"Profile 'coder' is already served by the default multiplexer"* instead of registering a stray unit or plist that could only sit dead. Add the bot token and the running multiplexer picks it up. The multiplexer is the single inbound process; a second profile gateway would double-bind that profile's platforms. A profile that deliberately wants a separate process opts out with `gateway.standalone: true` (see [No new per-profile gateways](#no-new-per-profile-gateways)); pass `--force` (accepted by `run`, `start`, `install` and `restart`) only where a boundary blocks the fold. The cross-profile lifecycle wrapper script earlier on this page is therefore **not** used in multiplex mode — manage the host or its named profiles directly. #### 2. HTTP-inbound platforms are reached via a `/p//` URL prefix HTTP-inbound traffic for a secondary profile arrives on the default profile's **one** listener under a profile prefix, **not** a second port: ``` # default profile POST http://host:8644/webhooks/ # the "coder" profile, same listener POST http://host:8644/p/coder/webhooks/ ``` An unknown or unconfigured profile in the prefix returns `404`. The shared listener is the default profile's `api_server` port (or its `webhook` port when no API server is enabled); it serves three kinds of profile-prefixed paths: - **`api_server` and `webhook` are mirrored**, never duplicated. `/p/coder/v1/...` and `/p/coder/webhooks/` are answered by the default profile's own adapter under coder's scope. A secondary must therefore **not** enable `api_server` or `webhook` itself (the dashboard refuses with `409`; an `API_SERVER_KEY` or `WEBHOOK_ENABLED` in the secondary's `.env` wires the credential without starting a listener). - **Every other inbound-port platform runs in shared-listener mode.** A secondary that configures Twilio SMS, LINE, Teams, BlueBubbles, Microsoft Graph, WhatsApp Cloud, WeCom callback or Feishu webhook mode gets its **own** adapter instance built without a port; the default listener forwards `/p//` to it. See [Inbound-port platforms under the multiplexer](#inbound-port-platforms-under-the-multiplexer). - **WhatsApp (bridge) runs per paired profile.** Pair each secondary with `hermes -p work whatsapp`. Each profile uses its own session and bridge port; an unpaired profile is skipped with `whatsapp_unpaired` and a pairing remedy. See [WhatsApp multi-profile setup](messaging/whatsapp.md#multiple-profiles). - **Relay remains shared ingress owned by the default profile.** Enable and configure Relay on the default profile, then route inbound to profiles via `profile_routes`. A secondary-only Relay configuration is reported as not served. A profile that opted out with `gateway.standalone: true` runs its own relay in its own gateway, as any standalone gateway does. Authentication follows the profile named in the URL. Unprefixed endpoints keep using the default listener's existing credentials. - `/p/coder/...` API-server requests must use `API_SERVER_KEY` from `~/.hermes/profiles/coder/.env`; the default listener key is rejected. Under the multiplexer that key only authenticates the prefix — it does not turn on a second `api_server` listener in the secondary profile, so you do not need to pin `platforms.api_server.enabled: false` in the secondary's `config.yaml`. - A webhook route that targets `coder` must declare `profile: coder` beside its existing route-specific `secret` in the default profile's `config.yaml`. That secret is then accepted only at `/p/coder/webhooks/` and is rejected on every other profile prefix. - Webhook routes without `profile` remain default-profile routes and are not reachable through a named profile prefix. Dynamic subscriptions bind the same way: `hermes webhook subscribe --route-profile coder` writes `profile: coder` into the default gateway's `webhook_subscriptions.json` and prints the `/p/coder/webhooks/` URL (`hermes webhook ls` shows the binding). Use `--route-profile`, not the global `-p coder`: `-p` would write the subscription into coder's own subscriptions file, which the default gateway's webhook adapter never reads. - Delivery follows the same binding. A `profile: coder` route's reply (or `deliver_only` message) goes out through **coder's** adapter for the `deliver` platform, falls back to **coder's** home channel when `deliver_extra.chat_id` is unset, and a `github_comment` delivery runs `gh` with `GH_TOKEN` / `GITHUB_TOKEN` from `profiles/coder/.env`. If coder has no adapter for that platform the delivery fails (502) rather than posting as another profile's bot; a default route likewise never borrows a platform that is enabled only on a secondary profile. - `/p/coder/api/platforms//events` callbacks are verified and dispatched by coder's adapter; when coder has none the callback is a 503. Named API requests fail closed when the target profile has no `API_SERVER_KEY`. Security configuration errors remain fatal: for example, an `open` own-policy platform without `GATEWAY_ALLOW_ALL_USERS` or its platform-specific allow-all opt-in still aborts gateway startup rather than silently dropping the unsafe profile. #### Inbound-port platforms under the multiplexer A standalone `hermes -p coder gateway run` binds coder's Twilio, LINE, Teams, … webhook servers on their own ports. Under the multiplexer those adapters are still coder's — same credentials from `profiles/coder/.env`, same `config.yaml`, replies sent through coder's channel — but they bind **no port**. The default profile's shared listener forwards `/p/coder/` to them, where `` is exactly the path the adapter would serve standalone. The request is verified by **coder's** adapter with **coder's** secret (Twilio auth token, LINE channel secret, Teams app credentials, BlueBubbles password, …) and runs under coder's runtime scope; the default profile's own `/path` is untouched, and a profile that has no adapter for a path gets `404`, never another profile's bot. | Platform | Secondary profile's callback URL on the shared listener | Verified with the named profile's | |---|---|---| | Twilio SMS (`sms`) | `https:///p//webhooks/twilio` | `TWILIO_AUTH_TOKEN` signature (`SMS_WEBHOOK_URL` must be this URL) | | LINE (`line`) | `https:///p//line/webhook` (media: `/p//line/media/...`) | `LINE_CHANNEL_SECRET` | | Microsoft Teams (`teams`) | `https:///p//api/messages` | Bot Framework token for `TEAMS_CLIENT_ID` | | BlueBubbles (`bluebubbles`) | `http:///p//bluebubbles-webhook` (registered with the server automatically) | `BLUEBUBBLES_PASSWORD` | | Microsoft Graph (`msgraph_webhook`) | `https:///p//msgraph/webhook` | `extra.client_state` | | WhatsApp Cloud (`whatsapp_cloud`) | `https:///p//whatsapp/webhook` | `WHATSAPP_CLOUD_APP_SECRET` / verify token | | WeCom callback (`wecom_callback`) | `https:///p//wecom/callback` | the app's callback token / AES key | | Feishu webhook mode (`feishu`) | `https:///p//feishu/webhook` | `FEISHU_VERIFICATION_TOKEN` / `FEISHU_ENCRYPT_KEY` | `` is the public hostname (tunnel, reverse proxy) in front of the default profile's listener; a custom `webhook_path` in the profile's config moves the path after `/p/` accordingly. The gateway logs the exact URL at startup: ``` [sms] profile 'coder' is served on the default profile's shared listener: http://127.0.0.1:8642/p/coder/webhooks/twilio (point the vendor's callback URL at this path ...) ``` and every status surface repeats it, so you know what to paste into the vendor console: ``` $ hermes -p coder gateway status ✓ Gateway is running via the default-profile multiplexer Manage it from the default profile: hermes gateway status Inbound callback URLs on the shared listener: line: http://127.0.0.1:8642/p/coder/line/webhook sms: http://127.0.0.1:8642/p/coder/webhooks/twilio ``` `hermes gateway status` and `hermes status` on the default profile list the same URLs per served profile, and the dashboard's Channels page and the Desktop Messaging page show them as each platform's `ingress_url` when viewing that profile. The default's own `api_server` and `webhook` are reported the same way for a served profile — as **connected** with `ingress_url` `http://127.0.0.1:8642/p/coder/v1` (respectively `.../p/coder/webhooks/`) — since the profile has no adapter of its own for them; it is the default's listener answering under the `/p/coder/` prefix. A per-profile `SMS_WEBHOOK_PORT`, `LINE_PORT`, `TEAMS_PORT`, … in a secondary's `.env` is ignored under the multiplexer (nothing binds); it applies again the moment that profile runs its own standalone gateway. #### 3. Per-credential platforms still need their own token per profile Polling/connection platforms (Telegram, Discord, Slack, Matrix, Signal, …) work fine multiplexed, but each profile that enables one must supply its **own** bot token — the same token cannot be polled by two profiles at once. If two profiles configure the same `(platform, token)`, the gateway logs an error naming both profiles and parks the **duplicate** adapter (it shows as `fatal / duplicate_credential` in runtime status) while the first claimant and every other profile keep running — the gateway itself does not exit. The default profile's adapters connect first and claim their credentials, so the parked adapter is always the secondary's (see [Token-conflict safety](#token-conflict-safety) — the rule is unchanged, it's just enforced inside the one process now). #### 4. Session keys are namespaced by profile Each profile's sessions live under an `agent::…` namespace so two profiles on the same platform/chat never collide in the shared session store. The **default** profile keeps the historical `agent:main:…` namespace byte-for-byte, so existing default-profile sessions are unaffected — no migration, no orphaned history. Every gateway path that reads a key back — delegation completions after a restart, shutdown notices, a per-user-thread `/stop` of a sibling's run, `/undo`, QQ approval buttons — accepts the `agent::…` shape too, so secondary profiles get the same behaviour as the default one. The one profile name that would collide with the default's namespace, a profile literally called `main`, is keyed `agent:main~:…` so it keeps its own sessions and its own `profiles/main/state.db`. Each profile's rows land in **its own** `state.db`: a named profile's under `profiles//state.db`, the default profile's under the launch home — even when the write happens inside another profile's routed turn or background tick. The Desktop/TUI backend's own store is likewise pinned to the home it launched under, and a Bot Chat's side agents (`prompt.background`) persist next to their parent conversation. #### 5. One PID/lock and one status surface There is a single process-level PID and lock (the multiplexer, under the default home). `hermes status --full` on the default profile reports the multiplexer and lists the profiles it serves (`Serves: coder, research`). `hermes -p coder status` and `hermes -p coder gateway status` report "running via the default-profile multiplexer" instead of "stopped". The dashboard's `/api/status?profile=coder` / Channels page report the multiplexer as coder's running gateway, with coder's own adapters as its platforms. The single `gateway_state.json` lives under the default home: secondary adapters appear there as `:` entries beside `served_profiles`; no per-profile gateway status file is written. `hermes -p coder cron status` names the single host gateway and the profiles it serves — `Scheduler host: the host gateway (PID 4211) serving profiles default, coder` — then checks coder's own ticker heartbeat and last successful tick. A missing or stale heartbeat produces a warning rather than an unconditional running verdict. `cron list` and `cron create` also warn when a served profile has no fresh heartbeat. `cron status` adds tick-failure details that those lightweight checks do not read. When no gateway owns the host role, `cron status` tells you to start the **one** host gateway (`hermes --profile default gateway install` / `gateway run`) and to make sure it serves this profile. Installing a per-profile service is shown only under `LEGACY (pre-multiplex topology, not recommended)`: it would start a second gateway process on the host. `hermes doctor` follows the same rule — under s6 it reports `Host gateway: the host gateway (PID 4211) serving profiles default, coder` instead of a per-profile slot count, flags any still-supervised per-profile slot as LEGACY, and checks the host systemd unit's linger even when you run doctor from a served profile. The `state.db` holder lines name the shared host process too, so "3 process(es) holding the DB open" says which gateway and which profiles stopping it would affect. #### What does **not** change Per-profile `.env` credential isolation is preserved and, if anything, stricter: a profile's keys are resolved from its own scope and are never unioned into a shared environment. Subprocesses like MCP servers and Kanban workers only ever see their own profile's secrets — including credentials injected by an external secret source (1Password, Bitwarden, …): a stdio MCP server started for profile B receives B's value for such a name, or nothing if B has none, never the default profile's. MCP servers are connected **per profile**: two profiles that both name a server `github` with their own token get two connections and each sees only its own tools; profiles whose `mcp_servers` entry is identical (same route *and* credentials, including mTLS `client_cert`/`client_key`) share one connection, and an owner's `/reload-mcp` re-registers the sharing profiles' tools without them reloading. `auth: oauth` servers are never shared across profiles: each profile holds its own token under its own `mcp-tokens/` and opens its own connection. Startup connects profiles one after another and, within a profile, at most `mcp.discovery_concurrency` servers at once (default 4, `0` = unlimited), so a fleet of profiles with many stdio servers no longer spawns every helper process in the same instant. Trust policy stays per profile: a `trust: untrusted` profile sharing a `trust: full` profile's connection is still asked before every write-capable call, and `supports_parallel_tool_calls` applies only to the profile that set it. Terminal settings (`terminal.backend`, `terminal.cwd`, `terminal.docker_volumes`, `terminal.docker_shared_container_key`, SSH targets, …) are likewise resolved per profile on every routed turn: a profile that omits a terminal key gets the documented default, never the launch profile's value, and a profile whose `config.yaml`/`.env` cannot be parsed has terminal execution refused rather than run under another profile's sandbox policy. The media-delivery credential guard (the denylist behind `MEDIA:` attachments — `.env`, `auth.json`, `config.yaml`, `state.db`, session transcripts, OAuth token stores) covers every profile under `profiles/`, so no profile's turn can attach another profile's secrets or chat history to a reply. Authorization is per profile too: `GATEWAY_ALLOW_ALL_USERS`, `GATEWAY_ALLOWED_USERS` and every platform allowlist or allow-all opt-in are read from the owning profile's `.env` — the default profile opting into open access never opens a secondary profile's bot, and a secondary that opts in only in its own `.env` is honored. The same holds for per-bot behaviour written in a profile's `config.yaml` (`require_mention`, `mention_patterns`, `allow_bots`, `reactions`, `auto_thread`, `free_response_auto_thread`, `dm_policy`, `ignored_channels`, Matrix `session_scope`, …): a secondary profile's YAML never lands in the shared process environment, so it cannot become the default profile's policy, and the default profile's YAML never governs a secondary bot. The `terminal.env_passthrough` allowlist, the Yuanbao auto-designated home channel, and the write guards protecting each profile's own `config.yaml` are resolved per profile as well. Kanban, profile-scoped skills/memory/SOUL, and model routing all behave per-profile exactly as they do with separate gateways. Outbound identity is per profile too. A turn running for profile `P` that calls the `send_message` tool (send, react, media) posts through `P`'s own bot; so do the "Gateway shutting down/restarted" and `/update` notices for `P`'s sessions, `/loop` wakeups set from `P`'s chats, and the Discord unauthorized-slash operator alert of `P`'s Discord bot (to `P`'s home channel). If `P` has no connected bot for that platform the send fails with a clear error — it never falls back to the default profile's bot. Tool and memory-provider credentials follow the same rule. Hosted OCR (`FIRECRAWL_API_KEY`), Modal / Browser Use cloud gates, the mem0 OSS OpenAI key, xAI video, and every memory-provider identity (`MEM0_USER_ID`, `SUPERMEMORY_CONTAINER_TAG`, `RETAINDB_PROJECT`, `OPENVIKING_ACCOUNT/USER`, `HINDSIGHT_BANK_ID`, `HERMES_HONCHO_HOST`) are read from the routed profile's `.env`, so a secondary profile's memories land in **its** account/bank/project (or the provider's per-profile default), never the default profile's. Custom endpoints travel with their keys — `OPENAI_BASE_URL`, `XAI_BASE_URL`, `NOUS_INFERENCE_BASE_URL`, `GATEWAY_PROXY_URL`, Firecrawl / Browserbase / RetainDB / Supermemory / Honcho / Hindsight URLs — so a profile's key is never sent to another profile's proxy or self-hosted server. `WEIXIN_HOME_CHANNEL`, `HERMES_LANGUAGE` and `display.language`, and `hooks.outbound[].secret_env` are likewise per profile, and end-of-session memory extraction for an evicted secondary session runs under that profile's scope. Per-turn runtime settings follow the routed profile as well: `agent.max_turns`, `fallback_providers`, `file_read_max_chars`, `tool_output.*`, `browser.*` timeouts, `timezone` (including the `TZ` handed to `execute_code` sandboxes), the media-delivery policy (`gateway.strict`, `media_delivery_allow_dirs`, `trust_recent_files*`) and the Nous `auth.json` used for auxiliary calls are all read from the profile serving the turn, never from the profile the gateway was launched under. The same holds for per-profile state files (`processes.json`, `checkpoints/`, sandbox snapshot stores, Feishu comment rules/pairing) and for gateway hooks: each profile's `hooks/` directory is loaded on its own and fires only for that profile's events. Shell hooks run with the routed profile's `HERMES_HOME`, without the default profile's secrets in their environment, and their stdin payload carries a `profile` field naming the profile that fired them. #### What is isolated per profile A quick reference for what a multiplexed turn resolves from **its own** profile and never shares with the default or any sibling: | Concern | Resolved from | Behaviour when the profile lacks it | |---|---|---| | Provider keys, bot tokens, `${VAR}` refs in `config.yaml` | The profile's own `.env` (its secret scope) | Unresolved / no adapter — never the default profile's value | | Authorization (`GATEWAY_ALLOW_ALL_USERS`, `GATEWAY_ALLOWED_USERS`, per-platform allowlists and allow-all opt-ins) | The owning profile's `.env` and `config.yaml` | Closed — a default-profile opt-in never opens a secondary's bot | | Slash-command gating (`allow_admin_from`, `user_allowed_commands`, `group_allow_admin_from`; see [Slash commands](../reference/slash-commands.md)) | The profile whose bot received the message — a secondary's own platform `extra` block governs its bots, not the default profile's | Fail closed: a served profile whose config the multiplexer has not loaded is gated with an **empty** admin list and no user-enabled commands, so only the always-allowed floor (`/help`, `/whoami`) runs — never the default profile's open policy | | HTTP endpoints (`/p//api/...`, `/p//webhooks/...`, platform event callbacks) | The named profile's `API_SERVER_KEY`, `profile:`-bound webhook routes, and its own adapter | `401`/`404`; delivery without an adapter is `502`/`503`, never another profile's bot | | Inbound-port platforms (`/p//webhooks/twilio`, `/p//line/webhook`, `/p//api/messages`, …) | The named profile's own adapter and its secret (Twilio auth token, LINE channel secret, Teams app, BlueBubbles password, …); replies leave through that adapter | `401`/`403` on a wrong secret, `404` when the profile has no such adapter — never the default profile's adapter | | Adapter settings (`*_REQUIRE_MENTION`, `*_REACTIONS`, `*_ALLOW_BOTS`, `*_PROXY`, Discord `allow_mentions`, Matrix `allowed_users` / `ignore_user_patterns`, webhook host/port/URL, Matrix thread/session/E2EE policy, Discord backfill/attachment caps, Buzz reply mode, A2A agent card / public URL, WhatsApp bridge policy, Yuanbao home channel) | The owning profile, in this order: explicit `.env` value → its `config.yaml` → the adapter's default | The adapter's documented default — never the default profile's setting.

(The former `gateway.multiplex_profile_allowlist` key is retired; a config migration removes it from `config.yaml`, and a profile you do not want served but that has not opted out is archived or deleted instead — `hermes profile delete `, or move the directory out of `profiles/`.) Deleted profiles leave a tombstone and are never enumerated; a profile whose directory is gone is never recreated by a served turn, the cron ticker or log routing. The served set controls `/p//` API and webhook prefixes, runtime status, profile-route eligibility, and which profiles the in-process cron scheduler ticks (the Desktop backend's ticker re-enumerates the same set on every cycle — a profile created or deleted while Desktop runs joins or leaves the ticked set without a restart — and stands down for any profile a running multiplexer or its own gateway already serves). A multiplexer started as `hermes -p gateway run` always ticks its own profile's cron store as well. The served set is **live**. A profile created while the multiplexer is running (`hermes profile create`, the dashboard, Desktop or the TUI) is served at once: the creator pings the multiplexer over its control socket, and the multiplexer also rescans `profiles/` every 30 seconds as a safety net. The new profile's adapters are built the moment its `config.yaml`/`.env` carries a bot token (creators usually create first, then add the token), `served_profiles` in the default profile's `gateway_state.json` is updated, and `hermes -p gateway status` reports it as served — no restart, and the other profiles' adapters and in-flight turns are untouched. Deleting a profile stops and unroutes its adapters the same way, and `hermes profile rename` unroutes the old name before the directory moves and hot-serves the new one (the old name is not resurrected by the adapters or the cron ticker that were still bound to it). The one-credential-one-poller rule still applies: a hot-added profile that reuses another profile's token is parked with a `duplicate_credential` error, never started as a second poller. ### Routing shared-bot chats to profiles (`profile_routes`) Multiplexing selects a profile per **credential** (each profile's own bot token) or per **URL prefix** (`/p//` for HTTP platforms). When several communities share **one** bot token — for example one Discord bot serving many guilds — you can additionally route specific users/guilds/channels/threads to different profiles with `gateway.profile_routes`: ```yaml gateway: multiplex_profiles: true profile_routes: # An entire Discord server → one profile - name: acme-server platform: discord guild_id: "1234567890" profile: acme # One channel in that server → a different profile - name: acme-support platform: discord guild_id: "1234567890" chat_id: "9876543210" profile: acme-support # A Telegram group (no guild concept — chat_id only) - name: tg-group platform: telegram chat_id: "-1001234567890" profile: tg-profile # A WhatsApp DM — write the phone number; JID and LID forms also match - name: owner-whatsapp platform: whatsapp chat_id: "15551234567" profile: owner # One Teams user across DMs, groups, and channels (exact sender id) - name: teams-owner platform: teams user_id: "00000000-0000-0000-0000-000000000000" profile: owner ``` Routes are matched by additive specificity: `user_id` = 16, `thread_id` = 8, `chat_id` = 4, and `guild_id` = 2. Thus `user_id + chat_id` (20) outranks `user_id` alone (16), which outranks every location-only route (at most 14). All declared fields must hold (AND), equal scores keep declaration order, and a route keyed on a channel also matches threads/forum posts whose parent is that channel. Messages that match no route stay on the default/active profile. The routed profile gets the full per-profile isolation described above (config, skills, memory, credentials, session namespace). Routing works on every platform adapter, not just Discord. `user_id` is the **sender** of the inbound message, compared for exact equality. It is only as trustworthy as the adapter that reports it, so treat it as an authorization input only on platforms whose ingress authenticates the sender. Sender ids are also namespaced per tenant on some platforms — a Slack user id is workspace-local — so on a gateway serving more than one workspace or server, pair `user_id` with the `guild_id` of that scope (Discord guild, Slack workspace, Matrix server) rather than relying on the id alone. Omitting `user_id` keeps the route unconstrained by sender for backward compatibility. Setting it to `null`, an empty string, or whitespace invalidates that route instead of broadening it to every sender on the platform. Sender routing selects a profile; it is not deny-by-default authorization. A sender that matches no route falls through to the default/active profile, exactly like an unrouted channel. To give one person a privileged profile and everyone else a restricted one, declare the privileged sender route first, add a platform-wide catch-all route to the restricted profile after it, and keep the platform's own ingress allowlist in place. A route applies only to messages received by the **default profile's bot** unless it names another bot with `bot_profile: `. Telegram DMs use the same `chat_id` for every bot (the user's id), so without this a `chat_id` route meant for the shared bot would also capture that user's DMs with a secondary profile's dedicated bot. Messages arriving at a secondary profile's own bot stay in that profile: ```yaml # Pin one user's DM with team_b's OWN bot to a third profile - name: teamb-owner-dm platform: telegram bot_profile: team_b chat_id: "72719239" profile: ops-for-team-b ``` Authorization for a routed message is always decided by the **receiving bot's profile** (its token and allowlist), including follow-ups sent while the agent is busy and mid-turn checks such as `/topic` or `/stop`; the routed profile itself needs no copy of the allowlist. A routed profile without a bot of its own also receives background notifications (process completions, heartbeats, async delegation results) through the shared bot after a gateway restart. On WhatsApp and WhatsApp Cloud, a `chat_id` route matches across user-identity forms: a bare phone number (`15551234567`), a JID (`15551234567@s.whatsapp.net`), and a LID (`…@lid`) all refer to the same person once the bridge has paired them (the same canonicalization session keys and adapter allowlists already use). You can put the phone number in `profile_routes` and inbound DMs still match whether WhatsApp delivers a JID or a LID. Without a LID mapping yet, the number form still matches a JID (the suffix is stripped) but cannot resolve an unknown LID — that inbound falls through to the default profile until the mapping appears. Group chats (`…@g.us`) are not sender identities and still match exactly. Telegram numeric ids are unchanged. `profile_routes` requires `gateway.multiplex_profiles: true`; with multiplexing off the routes are ignored. If an explicit route matches but its target profile is not installed (or was deleted), the gateway rejects that ingress and logs the route and target. It does not run the default profile. Traffic that matches no route keeps the historical default-profile behavior. Cron jobs owned by a routed profile deliver through the shared bot too, but only to targets an enabled route with a `chat_id`/`thread_id` maps to that profile (a `guild_id + chat_id` route qualifies its channel) — a routed profile's job targeting an unrouted chat (or a chat routed to another profile) is never sent through the shared bot. Guild-only routes do not qualify a cron target; add a `chat_id` route for the delivery channel. Routes declaring `user_id` do not qualify either: cron has no authenticated inbound sender, so they need a separate location-only route. The routed profile does not need its own `platforms.` block for this: the shared bot's authorization comes from the route, not from the satellite's config. ## Start, stop, or restart all gateways at once The CLI ships with single-profile lifecycle commands. To act across every profile, wrap them in a shell loop. Put the snippet below in `~/.local/bin/hermes-gateways` and `chmod +x` it: ```sh #!/bin/sh set -eu # Add or remove profile names here as you create / delete profiles. profiles="default coder personal-bot research" usage() { echo "Usage: hermes-gateways {start|stop|restart|status|list}" } run_for_profile() { profile="$1" action="$2" if [ "$profile" = "default" ]; then hermes gateway "$action" else hermes -p "$profile" gateway "$action" fi } action="${1:-}" case "$action" in start|stop|restart|status) for profile in $profiles; do echo "==> $action $profile" run_for_profile "$profile" "$action" done ;; list) hermes gateway list ;; *) usage exit 2 ;; esac ``` Then: ```bash hermes-gateways start # start every configured profile hermes-gateways stop # stop every configured profile hermes-gateways restart # restart all hermes-gateways status # status across all hermes-gateways list # delegates to `hermes gateway list` ``` :::tip The `default` profile is targeted with `hermes gateway ` (no `-p`), not `hermes -p default gateway `. The wrapper above handles both forms. ::: ## Manage one profile The shortcut commands every profile installs: ```bash coder gateway run # foreground (Ctrl-C to stop) coder gateway start # start the managed service coder gateway stop # stop the managed service coder gateway restart # restart coder gateway status # status coder gateway install # create the LaunchAgent / systemd unit coder gateway uninstall # remove the service file ``` These are equivalent to `hermes -p coder gateway ` — useful if a profile alias is not on `PATH` or if you target profiles dynamically from a script. ## Service files Each profile installs its own service with a unique name, so installations never clash: | Platform | Path | | -------- | ----------------------------------------------------------------- | | macOS | `~/Library/LaunchAgents/ai.hermes.gateway-.plist` | | Linux | `~/.config/systemd/user/hermes-gateway-.service` | The default profile keeps the historical names: `ai.hermes.gateway.plist` / `hermes-gateway.service`. ## Viewing logs Each profile writes to its own log files: ```bash # Default profile tail -f ~/.hermes/logs/gateway.log tail -f ~/.hermes/logs/gateway.error.log # Named profile tail -f ~/.hermes/profiles//logs/gateway.log tail -f ~/.hermes/profiles//logs/gateway.error.log ``` Stream every profile's log simultaneously: ```bash tail -f ~/.hermes/logs/gateway.log ~/.hermes/profiles/*/logs/gateway.log ``` The CLI also has a structured log viewer: ```bash hermes logs -f # follow default profile hermes -p coder logs -f # follow one profile hermes logs --help # filters, levels, JSON output ``` ## Identify what's actually running ```bash hermes profile list # profiles + model + gateway state hermes-gateways status # full status across every profile launchctl list | grep hermes # macOS — PIDs and labels systemctl --user list-units 'hermes-gateway-*' # Linux — units ``` ## Editing configuration Every profile keeps its config inside its own directory: ``` ~/.hermes/profiles// ├── .env # API keys, bot tokens (chmod 600) ├── config.yaml # model, provider, toolsets, gateway settings └── SOUL.md # personality / system prompt ``` The default profile uses `~/.hermes/` directly with the same three files. Edit them with any editor or via the CLI: ```bash hermes config set model.model anthropic/claude-sonnet-4 # default profile coder config set model.model openai/gpt-5 # named profile ``` After editing `.env` or `config.yaml`, restart the affected gateway: ```bash coder gateway restart # or, for everything: hermes-gateways restart ``` ## Keeping the host awake The gateway process can run all day, but the operating system will still try to sleep when idle. Two patterns: ### macOS — `caffeinate` `caffeinate` is built into macOS and prevents sleep while it runs. No install. ```bash caffeinate -dis # block display, idle, and system sleep caffeinate -dis -t 28800 # same, auto-exit after 8 hours caffeinate -i -w $(cat ~/.hermes/gateway.pid) & # awake while default gateway runs # Persistent: run in background and forget nohup caffeinate -dis >/dev/null 2>&1 & disown # Inspect / stop pmset -g assertions | grep -iE 'caffeinate|prevent|user is active' pkill caffeinate ``` | Flag | Effect | | ------ | ------------------------------------------------- | | `-d` | block display sleep | | `-i` | block idle system sleep (default) | | `-m` | block disk sleep | | `-s` | block system sleep (AC-powered Macs only) | | `-u` | simulate user activity (prevents screen lock) | | `-t N` | auto-exit after `N` seconds | | `-w P` | exit when PID `P` exits | :::warning Lid-close still sleeps the Mac `caffeinate` cannot override the hardware-driven lid-close sleep on MacBooks. For lid-closed operation, change your Energy Saver / Battery preferences or use a third-party tool. ::: ### Linux — `systemd-inhibit` or `loginctl` ```bash # Inhibit suspend while a command runs systemd-inhibit --what=idle:sleep --who=hermes --why="gateways running" \ sleep infinity & # Allow user services to keep running after logout (recommended) sudo loginctl enable-linger "$USER" ``` After enabling lingering, your systemd user units (including `hermes-gateway-.service`) continue running across SSH disconnects and reboots. ## Token-conflict safety Each profile must use unique bot tokens for each platform. If two profiles share a Telegram, Discord, Slack, WhatsApp, or Signal token, the second gateway refuses to start with an error naming the conflicting profile. Under [multiplexing](#alternative-one-gateway-for-all-profiles-multiplexing) the same rule parks only the duplicate profile's adapter and the shared gateway keeps running. To audit: ```bash grep -H 'TELEGRAM_BOT_TOKEN\|DISCORD_BOT_TOKEN' \ ~/.hermes/.env ~/.hermes/profiles/*/.env ``` ## Migrating from per-profile gateways If your profiles each run their own gateway today (one systemd unit or launchd agent per profile, from a release before multiplex-only), the default gateway's boot preflight keeps it standalone until they are folded (the unset default never double-binds a running fleet). `hermes update` folds them for you unless a real boundary blocks it (below); the same fold is one command, and re-running it on a half-migrated host (flag on, a unit left behind, a crash between the two) finishes the job instead of reporting "already multiplexed": ```bash hermes gateway migrate --multiplex --dry-run # print the plan and any blockers; changes nothing hermes gateway migrate --multiplex # apply (asks for confirmation on a TTY; -y skips) ``` There is no `--standalone` reverse command: a per-profile fleet is not a supported target. A blocked fleet keeps running as it is, and each profile keeps `hermes -p gateway install --force` as its path — or opts out of the host gateway with `gateway.standalone: true` (see [No new per-profile gateways](#no-new-per-profile-gateways)), which `hermes gateway migrate --multiplex` respects. ### Docker / Hermes Cloud (s6-supervised container) Inside the official image every profile has an s6 slot (`/run/service/gateway-`). The container's boot registers every *named* slot down and folds its autostart intent into the root slot, so a fresh boot already multiplexes. An **in-place** update no longer needs a container restart to converge either: `hermes gateway migrate --multiplex` (and the hook `hermes update` runs) parks any named slot that is still up (`s6-svc -d` plus a `down` file so a supervisor restart does not revive it), folds its intent into the root slot through the same rule the boot uses, and restarts the root slot. A registered-down slot is never a blocker — only a slot that is actually up is. The one thing the command still cannot do from inside is create a root slot the boot never registered; that case names itself and asks for a container restart. ### What `hermes update` does After a successful update, when the install has two or more profiles, at least one secondary profile runs its own gateway (a live process or an installed service) and `gateway.multiplex_profiles` is off, `hermes update` runs the same preflight: - **Nothing blocks it** → the migration runs automatically (the same code path as `hermes gateway migrate --multiplex --yes`) and prints what it did. This is deterministic and never prompts, so it also runs on headless/cron updates. - **Something blocks it** → a warning block lists each blocker with its exact fix and the one-liner to run later. Nothing is changed. Single-profile installs are never migrated (there is nothing to gain), and an install that is already multiplexing is left alone. `hermes update` also does nothing when no secondary profile runs its own gateway — it never flips modes on an install where nothing was running. ### Boundaries `hermes update` never crosses on its own The unattended hook only folds profiles that share **one UNIX user, one service domain and one `profiles/` tree** — the shape `hermes profile create` produces. A standalone secondary behind any of these boundaries stops the automatic path: | boundary | example | |---|---| | different service manager or scope | default on user systemd, a secondary on **system** systemd (or launchd), or the default detached with a service-managed secondary | | more than one installed unit on a profile | a user **and** a system unit for the same profile (the explicit command removes both) | | different UNIX user | a system unit with its own `User=`, or a live gateway owned by another uid; a system unit whose `User=` this host cannot resolve — on the secondary **or** on the default — counts as unknown, never as "same user" | | `HERMES_HOME` outside `/profiles/` | a unit pinning `HERMES_HOME=/opt/hermes/profiles/emma` | In that case `hermes update` prints the boundary it found plus `hermes gateway migrate --multiplex`, and changes nothing — no unit is removed and the per-profile gateways keep running (`--force` remains their path where a boundary like these blocks the fold; a profile free of them opts out with `gateway.standalone: true`). Collapsing such a fleet replaces a kernel-enforced boundary (file ownership, `User=`) with in-process isolation, which is an operator's decision. The explicit command still makes it: the same findings appear as **notices** in `hermes gateway migrate --multiplex --dry-run` so you can read them first, and `--multiplex` proceeds when you confirm. ### Opting out of the automatic migration Set `gateway.auto_multiplex_migration: false` on the **default** profile to keep the automatic fold from ever running on this install: ```bash hermes config set gateway.auto_multiplex_migration false ``` `hermes update` then leaves per-profile gateways exactly as they are, with no output and no changes, however eligible the install looks. The setting lives in config, so it survives updates — the decision is made once rather than re-litigated on every release. It is read from the effective config like every other setting, so a value pinned in the managed scope (`/etc/hermes/config.yaml`) wins over the profile's own file. It governs the **automatic** path only: `hermes gateway migrate --multiplex` is an explicit request and still migrates (and is the supported way to opt back in). Absent or `true` keeps the default behaviour described above. The explicit command is different: `hermes gateway migrate --multiplex` with two or more profiles and **no** standalone secondary gateway still applies the one remaining step — it sets `gateway.multiplex_profiles: true` and (re)starts the default gateway. You asked for multiplex; you get multiplex. :::tip Clones do not carry channels `hermes profile create --clone` leaves the source's bot tokens and allowlists behind (see [Profiles → messaging channels are never cloned](./profiles.md#messaging-channels-are-never-cloned---clone-channels-to-opt-in)), so a fleet of clones no longer trips the duplicate-credential blocker below. Older clones that still carry them are flagged by `hermes profile list`. ::: ### What the migration does 1. Stops each secondary profile's standalone gateway and uninstalls its service (systemd user/system unit or launchd agent). What was removed is recorded in `~/.hermes/gateway_migration.json` for rollback. 2. Sets `gateway.multiplex_profiles: true` in the **default** profile's `config.yaml`. 3. Restarts the default gateway — or installs and starts it on the same service manager the secondaries were using, so a systemd-managed fleet stays systemd-managed. 4. Waits for the default gateway to record `served_profiles` covering every profile, then prints a summary. ### Blockers and fixes | Blocker | Why | Fix | |---|---|---| | Two profiles configure the same platform credential (e.g. the same `TELEGRAM_BOT_TOKEN`) | Under one process a bot token can only be polled once; the multiplexer would park the duplicate and that profile's bot would go silent | Remove the token from the second profile, or keep it in `default` and route that profile's chats with [`profile_routes`](#routing-shared-bot-chats-to-profiles-profile_routes) | | A secondary profile enables a port-binding platform that has **no** `/p//` ingress on the default listener | The multiplexer skips that whole profile (see [rule 2](#2-http-inbound-platforms-are-reached-via-a-pprofile-url-prefix)) | Disable the platform in that profile (`platforms..enabled: false`), or run the profile standalone: set `gateway.standalone: true` in its own `config.yaml` and wait for the host to rescan (at most 30 seconds), or send its `rescan-profiles` control verb. Use `hermes -p gateway install --force` only where a boundary blocks the fold. | The credential check reuses the gateway's own conflict detection, so its verdict matches what the multiplexer does at startup. Which port-binding platforms have a `/p//` ingress is read from the adapters themselves (each declares `serves_profile_prefix`), so the preflight stays correct as new HTTP-inbound adapters gain the prefix. ### What changes for inbound-port profiles A secondary profile that used `api_server` or `webhook` on its own port is **not** blocked — but its URL changes. The preflight prints the exact new URL, for example: ``` Profile 'coder': api_server moves onto the default listener at http://127.0.0.1:8642/p/coder/v1/... (its key/secret is unchanged; update clients that call the old per-profile port). ``` The profile's own `API_SERVER_KEY` / webhook secret keeps authenticating the prefixed URL; nothing else about the key changes. ### Profiles created after the migration A profile created while the multiplexer runs is served without a restart (see above). `hermes profile create` confirms this when the live multiplexer picked the profile up; it prints the `hermes gateway restart` reminder only when it could not reach the multiplexer (for example, a gateway started from an older build). ### Failure handling and resuming The migration is transactional. Failures it can see coming from the plan (a system unit that would have to run as root without a recorded `User=`, a config file it cannot rewrite) are refused before any per-profile gateway is stopped. Anything that fails after the manifest is written — the flag write, a later secondary's stop or unit removal, the default's install or start — rolls back through the manifest on the spot, so no profile is left without a gateway. Should the process die anywhere in that window, the next `hermes gateway migrate --multiplex` sees the flag on, the manifest, and no live multiplexer serving the migrated profiles (an installed but stopped default unit does not count) and resumes from the manifest instead of reporting "already multiplexed". A manifest on disk always means *unfinished*: it is the resume record, not a rollback command — there is no `--standalone` reverse, and the compensator above only ever runs inside a single failed apply so that no profile is left without a gateway. Not covered automatically: s6-supervised containers — they converge on the next container start (the per-profile slots are registered down and the root gateway multiplexes; a `gateway.standalone: true` profile boots its own slot from its own run intent instead). Windows Scheduled Tasks are folded by the command. The dashboard's System page offers the same migration as a button when the preflight finds an eligible install. ## Updating the code `hermes update` pulls the latest code once and syncs new bundled skills into every profile: ```bash hermes update hermes-gateways restart ``` Running gateways are restarted by the update itself; on an install that still runs one gateway per profile, the update then runs the [migration to a single multiplexed gateway](#migrating-from-per-profile-gateways) — automatically when nothing blocks it, otherwise as a warning naming the boundary (different UNIX user, `HERMES_HOME` outside `profiles/`) and the one-liner to run yourself. User-modified skills are never overwritten. ## Troubleshooting ### "Could not find service in domain for user gui: 501" You ran `hermes gateway start` after a previous `hermes gateway stop`. The CLI's `stop` does a full `launchctl unload`, which removes the service from launchd's registry. The CLI catches this specific error on `start` and automatically re-loads the plist (`↻ launchd job was unloaded; reloading service definition`). The service starts normally. Nothing to fix. ### Stale PID after a crash If a profile's gateway shows `not running` but a process is still alive: ```bash ps -ef | grep "hermes_cli.*-p " cat ~/.hermes/profiles//gateway.pid kill -TERM # graceful kill -KILL # if that fails after a few seconds gateway start ``` ### Forcing a hard reset of one service ```bash # macOS launchctl unload ~/Library/LaunchAgents/ai.hermes.gateway-.plist launchctl load ~/Library/LaunchAgents/ai.hermes.gateway-.plist # Linux systemctl --user restart hermes-gateway-.service ``` ### Health check ```bash hermes doctor # default profile hermes -p doctor # one profile ```
