1KOMMA5°
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.
1KOMMA5° publishes 28 API contracts indexed on the APIs.io network, including Admin - Audit Logs API, Admin - Branches API, Admin - Concepts API, and 25 more. Tagged areas include Company, Energy, Solar, Renewable Energy, and Smart Home.
The 1KOMMA5° catalog on APIs.io includes 1 Spectral governance ruleset.
1KOMMA5°’s developer surface includes support, engineering blog, authentication, and 29 more developer resources.

Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| IoT and Smart Home | covered | 17.2 (thin) | - | - |
| ENERGY STAR Certified Products (appliances, electronics, data-center equipment, EV chargers, smart thermostats) | covered | 17.2 (thin) | - | - |
| Home Assistant Custom Integrations (HACS) | covered | 17.2 (thin) | - | - |
| LF Energy Projects and Members (grid, DER, EV charging open source) | covered | 17.2 (thin) | - | - |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
