Temperature and humidity sensor – indoor

Prevent your rooms from becoming too humid and keep an eye on the temperature: with the Homematic IP temperature and humidity sensor - indoor.

Interior spaces protected against excessivehumidity

The air is often too damp in rooms where there is a washing machine, dryer or laundry racks. This increases the risk of mould forming. The Homematic IP temperature and humidity sensor lets you always keep an eye on humidity levels. In conjunction with radiator thermostats or underfloor heating actuators, you control the room temperature. If the humidity is too high, you will receive a ventilation recommendation in the app. That lets you minimise mould the smart way. 


Comfort temperature at any time

Control the room temperature according to your needs - even when you're out and about.


You can do this easily via the app, in conjunction with one or more Homeatic IP radiator thermostats and underfloor heating actuators.

Design mit Pfeil

Great flexibility from a modular design

Use the sensor to suit your individual needs thanks to the flexibly combinable design. 

  • Integration into existing switch series with Size 55 frames of the most popular manufacturers 
  • Adhesive or screw mounting in the supplied interchangeable frame with the supplied mounting material 
  • Mounting on a free flush-mounted box with the mounting plate optimised for this purpose 
  • Integration into the Homematic IP desk 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) .

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. You can also use the sensor in conjunction with Homematic IP radiator thermostats, underfloor heating actuators and switch actuators for electric radiators.

Homematic IP means modern, flexible and secure technology from the European market leader*. Let the advantages of our system win you over, and start living smarter straight away. 

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.
