I have a switch in a wall box in which I have a 230V power supply. Under this switch I would like to hide a module which will control wirelessly two modules which will switch independently two different lighting circuits. Unfortunately I do not have the possibility of controlling directly from this box. I don't know if there is such a solution at all, although there probably is
How it is supposed to work (because I don't know if what I wrote above is clear) in the box with the switch (it can be a mono or bi-stable switch) there is supposed to be module A which will remotely switch on/off modules B and C after pressing the left or right button respectively. It cannot be a whole wireless switch because it is important that it stays what it is so that the switches look identical throughout the room. Both in the box with the switch and in the places of modules B and C there is an N and L wire of the 230V installation.
All modules will be in the same room 2-3m from each other
