About

1KOMMA5GRAD is a Home Assistant integration for 1KOMMA5° Heartbeat energy systems, using the vendor's cloud. It adds binary sensors, calendars, numbers, selects, sensors, switches and time entities, including energy sensors that suit the Energy Dashboard. It also exposes the battery and heat pump decisions planned by Heartbeat AI as sensors and calendar events, which can be used in automations for loads Heartbeat does not control. Setup happens in the UI with the Heartbeat account username and password, and the refresh interval for live data can be changed in the options. Diagnostics sent to the developer are disabled by default. It works only with the newer Heartbeat API, which is not available in all regions, and it is not supported by 1KOMMA5GRAD.

Send diagnostics (errors, logs, performance traces)Sends diagnostics from this integration to the developer via Sentry. Disabled by default. This includes errors and warnings with stack traces, log messages of this integration, and performance traces of data refreshes and API requests (URLs without query parameters, status codes and timings; a sample of requests on releases, all on pre-releases). If the 1KOMMA5GRAD API returns an error or an unexpected response, the structure of the response (field names and types, never your values) is included so API changes can be detected. Everything is tagged with the integration version and your Heartbeat system ID. No credentials, name, email address or host information is sent.
