Temperature and humidity under control

Especially on winter days, you want to have a pleasantly warm temperature in the bathroom but also low humidity. You can regulate both with the Homematic IP temperature and humidity sensor. This not only allows you to keep an eye on the humidity, but also to control your radiator thermostats or underfloor heating actuators even more efficiently. And if needed, you get a ventilation recommendation - it's all in the app!

Comfort temperature at any time

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

Do that easily with the app in conjunction with one or more Homematic IP radiator thermostats and underfloor heating actuators.

Great flexibility thanks to a modular design

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

Integration into existing switch series with a Size 55 frame 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.
