The Homematic IP radiator thermostat basic is part of the Homematic IP smart home system and actively helps save energy. This smart controller replaces conventional radiator thermostats, allowing for energy savings of up to 30%. The thermostat is mounted on the radiator without any intervention in the heating system and without tools. It is powered by two AA batteries, which can provide energy for approximately 2 years. The radiator thermostat is ready to use immediately thanks to a pre-set heating profile, which can be manually adjusted at any time if needed. Individual temperature profiles with up to 13 changes per day are possible, ensuring that Homematic IP only heats specific rooms when there is actual demand.

Setup can be done flexibly on the device itself, via the Homematic IP app, or through a browser-based interface. Alternatively, the smart thermostat can also be operated without a central unit: the stand-alone operation allows for the direct pairing of up to eight window and door contacts with magnets to automatically lower the room temperature when ventilating. Through the app, the radiator thermostat can be integrated into a comprehensive smart home system. The cloud solution allows for temperature adjustments at any time from any location. For those who prefer to keep data local within their home network, setup through the central unit is also available.

The wall thermostat enables a time-controlled regulation of room temperature in conjunction with Homematic IP underfloor heating actuators or Homematic IP radiator thermostats.
