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.
The control itself is done via switches, Apps or via in openHAB deposited rules.
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 following smarthome rules have been implemented so far
- The shutters are lowered when it is warmer outside than inside and at the same time it is warmer inside than the comfort temperature. In addition, a window is shaded only if it according to the sun’s position at all sun.
- 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.
- and at sunrise and simultaneous absence
All used openHAB rules are part of my deployment project and can be tried or downloaded there. Alternatively, they can also be obtained directly from my Github Repository.
