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!
