Radiator thermostat - compact plus

Smart heating - particularly persistent and tamper-proof with the radiator thermostat - compact plus.  

Up to 7 years battery life, tamper-proof - the smart heating thermostat for the housing industry

Specially developed for the requirements of housing and building management: the Homematic IP radiator thermostat - compact plus. With a battery life of approx. 7 years, the thermostat is particularly low-maintenance and tamper-proof thanks to the optional dismantling protection and the sealing of the battery compartment. With the three adjustable heating profiles and 13 possible changes per day, up to 33 % of heating costs* can also be saved.


Comfortable temperature at all times

The thermostat controls the room temperature individually.


You can do this easily via the app, directly on the unit using the buttons or conveniently via voice control (using Amazon Alexa or Google Assistant).

Safe and low maintenance

Ideal for offices, doctors' surgeries, businesses or children's rooms: The closed housing design does not allow any unwanted manual operation or manipulation and does not protrude into the room. The battery life of 3 years also makes the radiator thermostat particularly low-maintenance.


You can set heating profiles via the Homematic IP app, a wall thermostat or by voice control. The disassembly protection included in the scope of delivery provides additional security.

With some smart home providers, you have to make a choice: Do you have everything wired, or do you go fully wireless? Some systems are also hermetically sealed and do not accept devices from other manufacturers. Here at Homematic IP, we have a different approach. We are guided by you!

The Homematic IP app

Configure all the settings for your smart home in the Homematic IP app, and use it to control, regulate and monitor your devices whenever you want – without providing any personal data!
A smart home system is particularly robust, interference-proof and reliable when the devices communicate with each other via wired connections. And data transmission is very fast with cables, too. That all comes together with Homematic IP Wired.
