I have noticed that other manufactures use a Micro module to be installed behind the juntion boxes. This type of devices brings a lot of wire and labor saving , making the instalation a lot easier .
Yes i am aware of the models you describe , and they are interesting , but as you know a tipically sleeping room with two windows/openings , needs about 10 inputs in average for switches , so one device per room could collect all inputs, this would save a lot of labor labor and wiring.
Having outputs are not so relevant because the inductive load capacity is to low to control motors found at blind shutters. Dou you agree or could point me a better solution ?
