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 1 API on the APIs.io network: Offer Tool API. Tagged areas include Company, Energy, Solar, Renewable Energy, and Smart Home.

1KOMMA5°’s developer surface includes support, engineering blog, authentication, and 23 more developer resources.

Where this information came from

This is an independent, third-party profile of 1KOMMA5°, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
