Opened, tilted or closed? It's detected!

On a warm summer evening you're sitting outside on the terrace and enjoying the sunset - until at 9:30 pm the shutters of the terrace door descend as usual. Now you have to quickly jump into the house before the route through the door is closed off. You can eliminate this stressful situation. The Homematic IP window handle sensor detects the position of the window handle and thus whether your window is tilted, open or closed. In combination with a shutter actuator, you also make the shutters on the patio door smart. So the shutters only go down when the door is closed.
