Save energy and get more security.
While you're out, it suddenly starts pouring with rain and you wonder if all the windows - especially the skylights - are closed. Should you rush home just in case? Not if you've installed the Homematic IP window / door contact. This allows you to easily check in the app whether all windows are closed when you're out and about. And by the way, you can also integrate this all-rounder into your Homematic IP security or heating function.
