// 1 = skip WiFi entirely and just print readings to the Serial Monitor, fast.
// 0 = normal operation: read, and POST to the base station.
//
// START AT 1. Prove the probe reads through the ESP8266 before you add WiFi to

// trick to bringing hardware up.

// ─── WiFi ───────────────────────────────────────────────────────────────────
// The hotspot from Module 4 (the Android base station). Ignored in bench mode.

// ─── Where to send readings ─────────────────────────────────────────────────
// LEAVE POST_URL EMPTY and the node finds the base station by itself.
//
// The phone running the hotspot IS this node's gateway, by definition — so the
// node already knows its address the moment it connects, and builds the URL from
// POST_PORT and POST_PATH below. You never have to look up an IP.
//
// This is not just convenience. Android RANDOMISES the hotspot subnet: ours came
// up on 10.215.63.55, not the 192.168.43.1 every guide quotes, and it can shuffle
// again on any hotspot restart or reboot. A hardcoded IP goes stale silently —
// every node in the field stops reporting and the only symptom is nothing at all.
//
// Set POST_URL only to override: a real server on the LAN, a different host, etc.
//   #define POST_URL "http://192.168.1.50:1880/water"
#define POST_URL       ""
#define POST_PORT      1880
#define POST_PATH      "/water"

// Test the endpoint before you blame the firmware — from any device on the hotspot:
//   curl -X POST http://<phone-ip>:1880/water \
//        -H 'Content-Type: application/json' -d '{"node":"test","ok":true,"depth_mm":500}'
// The node prints the phone's address on serial as `gateway :` when it connects.

// Name for this node. If you ever run two tanks, give them different names.
#define NODE_ID        "water-tank-1"

// How often to read and send, in seconds. Ignored in bench mode, which polls
// every 2s so you get a fast feedback loop while wiring.

// ─── Sensor calibration ─────────────────────────────────────────────────────
// THE DRY READING. Power the probe up sitting in air (not in the tank) and read
// the raw value — see Step 4 of the Module 2 page on the site. It will NOT
// be zero. Ours read 26. Put YOUR number here.
//
// This is per-probe and it drifts over months. Re-measure if readings look off.
#define DRY_OFFSET_COUNTS  26

// ─── Your tank ──────────────────────────────────────────────────────────────
// Water depth above the probe when the tank is FULL, in mm. Measure this once.
// Set to 0 if you don't know it yet — the node will report depth in mm and
// simply omit the percentage.
