Wall thermostat with humidity sensor - 2

Provides your personal comfort temperature

You get home on a cold and wet winter day longing for warmth and comfort. With Homematic IP , you enter inside your own four walls and always have the indoor climate that you need. Placed freely in the room, the wall thermostat optimally measures temperature and humidity and passes on all commands to the radiator thermostats. That means your home is always at the right temperature – not too warm and not too cold. Saving you up to 33 %* of valuable heating energy.

Comfort temperature at any time

Control the room temperature according to your needs - whether you're at home or out and about.

You can do this easily via the app, directly on the device using the dial in 0.5 ° steps or conveniently via voice control (using Amazon Alexa or Google Assistant.

Retrofitting made easy

You can freely place the wall thermostat in the room to measure the room temperature from the right location.

Installation is very simple: without wiring, through battery operation and radio communication.

Flexible control possibilities

With the Homematic IP Access Point and the free app, you lay the foundation for your smart home: your radiator thermostat is integrated into it and you can smartly supplement many devices in your home.

The easy way to save heating costs and CO₂ emissions

You can easily set the individual temperature curves in the Homematic IP app.

With up to three adjustable heating profiles and 13 changes per day, you always heat only when you want to. The open window detection ensures that the temperature is lowered during ventilation.

Great flexibility thanks to a modular design

The combinable design allows the wall thermostat to be used very individually.

Adhesive or screw mounting in the supplied interchangeable frame with the supplied mounting material
Integration into existing switch series with a Size 55 frame of the most popular manufacturers
Mounting on a free flush-mounted box with the mounting plate optimised for this purpose
Integration into the Homematic IP desktop stand (HmIP-DS55) for a longer battery life
As an alternative to battery operation, the wall thermostat can also be supplied with 230 V via the Homematic IP power supply unit for brand switches (HmIP-BPS).
