About

ThermIQ MQTT Integration controls and logs Thermia heat pumps through the ThermIQ-MQTT interface. It connects locally over MQTT and uses the ThermIQ-MQTT and ThermIQ-Room2 hardware interface to monitor and control a Thermia or Danfoss heat pump. It adds binary sensors, numbers, selects, sensors and switches to Home Assistant. Settings cover the MQTT node name, the language, hexadecimal register format in MQTT, an MQTT debug mode, and a request to migrate old data in the recorder database. The repository also ships a dashboard card with an animated widget, where pipe colour follows temperature. It is set up in the UI and needs the Marketplace, which is HACS on 2026.10 and older.

From the README

The animated widget: pipe colour tracks temperature all the way round the machine. A screenshot from a live installation, with the pump idle — when it runs, the flows animate and the compressor turns. This integration allows you to use the ThermIQ-MQTT and ThermIQ-Room2 hardware interface to control and monitor your Thermia or Danfoss heatpump from Home Assistant. It is actively supported both here and at Thermiq.net
