When installing the windows, roller shutters with electric motors were used. Here you should pay attention to the correct wiring.
Connect the shutters
All roller shutter motors should fed with a 5-core cable to the central control cabinet in the main distribution room and then connected to a KNX shutter actuators.
A nice side effect is that you can easily implement a central opening and closing mechanism in this way.
Furthermore, the controllable shutters are also used for automatic shading or darkening. For this, openHAB rules evaluate various sensors and control the shutters based on them.

- The shutters are lowered at sunset. But this only happens with the windows closed. This prevents you from being locked out when you are still on the terrace in the evening.
