description: '1KOMMA5° (1Komma5 Grad) is a Hamburg, Germany headquartered smart-energy
  company that sells, installs and operates integrated residential energy systems —
  rooftop photovoltaics, battery storage, heat pumps and EV charging — and ties them
  together with Heartbeat AI, its energy-management platform. Heartbeat aggregates
  customer hardware into one of Europe''s largest residential virtual power plants,
  optimising self-consumption and trading household flexibility against day-ahead and
  intraday electricity markets. The company operates across Germany, Australia, the
  Netherlands, Sweden, Finland, Denmark and Belgium. Its machine-readable surface is
  small and mostly internal: a live OpenAPI 3.0 for the Offer Tool API used by its
  sales and partner network, an Auth0-backed OIDC provider at auth.1komma5grad.com,
  and the undocumented Heartbeat customer API that its mobile apps and community-built
  Home Assistant integrations consume.'

  description: 'The Offer Tool API backs 1KOMMA5°''s sales configuration and quoting
    workflow — customers and sites, product and pricebook catalogues, concepts, effective-price
    simulation for the German market, offer configurations, PDF offer generation, CRM
    deal lookup, and tenant/branch/user administration with audit logging. It serves
    a live OpenAPI 3.0.0 description at /swagger-json covering 60 paths, 73 operations
    and 130 component schemas. Access is bearer-token gated (Auth0); the Swagger UI
    at /swagger is behind HTTP Basic.'

    mobile apps and the Heartbeat AI platform — sites and systems, live power snapshots
    for PV, battery, heat pump and EV charger, energy summaries, dynamic electricity
    prices from the energy trader, self-sufficiency figures and Heartbeat AI optimisation
    decisions. 1KOMMA5° publishes no developer documentation and no machine-readable
    description for it; the host was probed live (an anonymous 200 on /api/v1/supported-versions)
    and the surface is additionally documented by community-built Python clients and
    Home Assistant integrations. Authentication is OAuth 2.0 authorization code + PKCE
    against auth.1komma5grad.com.'
