Temperature and humidity sensor – outdoor, anthracite

With the smart temperature and humidity sensor for outdoors, you always have an eye on the weather and can control various functions in your smart home.

Keep an eye on temperature and humidity

Winter, when the outside temperature is freezing, is exactly the time when you'd prefer to keep your windows closed to keep the heat inside the house. However, insufficiently frequent ventilation can cause mould to develop. With the Homematic IP temperature and humidity sensor for outdoor use, you can minimise this risk the smart way. The humidity indoors and outdoors is permanently compared in combination with a Homematic IP wall thermostat with humidity detection. You then receive a ventilation recommendation in your app when needed and only need to ventilate when it is really necessary.

In conjunction with a wall thermostat with humidity sensor (e.g. HmIP-WTH-2), the units always balance the humidity indoors and outdoors. You can get a ventilation recommendation if you want one.

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.
