I am also looking for roller shutter controller, did you manage to get this work?
I was thinking of how do you prevent that both up and down commands are sent to the roller shutter by accidentally pressing both halves of the switch
Voltage seems OK, and I guess the rated power should be sufficient (I am not sure what is the requirements of my motor).
But there is no protection from accidentaly pressing both buttons up and down at the same time which might cause short circuit.
Do you know if anybody produces or plans to develop dedicated roller shutter controller?
