Product details

Flexible heating - and save energy at the same time. If you want to heat according to your individual preferences and save energy at the same time, the radiator thermostat - flex from Homematic IP is a particularly clever and well thought-out solution. It can even be operated without your own smart home system. With three individually adjustable heating profiles and 13 possible changes per day, you can save up to 33% on heating costs. The large, high-contrast e-paper display makes it easy to read the temperature and can be adapted to the installation orientation. The display can be further customised by selecting from the detailed and reduced displays.

Installation: The radiator thermostat - flex is easily installed on the radiator without interfering with the heating system. The scope of delivery includes a high-quality metal union nut for secure installation on all standard radiator valves with an M30 thread and two AA batteries, which provide power for up to 3 years.

Setting: After installation, you can use the free Homematic IP app to set individual temperature profiles - with up to 13 changes per day in three adjustable heating profiles. For example, you can enjoy a pre-heated bathroom in the morning, save valuable heating energy when you are away and enjoy the desired room temperature in the living room at the end of the day.

Control: Control the Homematic IP Radiator Thermostat - flex directly on the device using the buttons, conveniently via the app, whether at home or on the move, or simply by voice control via Amazon Alexa or Google Assistant. With a Homematic IP Access Point, you lay the foundation for your smart home: your radiator thermostat - flex is integrated into it and you can add many other devices in a smart way.

Smart highlight: The Homematic IP Radiator Thermostat - flex reacts really smart in combination with window open detection.
