Weather sensor – pro

All the weather data at a click.

The weather changes in a flash, the clouds close in, it gets dark - a summer storm's coming. If your awning is extended when that happens, you can only hope that it will survive the storm undamaged. With Homematic IP, you no longer have to worry about this nightmare. The weather sensor - pro reliably records all weather data such as temperature, wind, rain and humidity. Combine it with other Homematic IP devices to control your smart home even more smartly.
