[Solved] Which central roller shutter controller with switch and app do you recommend?

Hi, I'm finishing the electrical installation in my house and have a question about the roller shutter control. I've had a tradesman lay me wires according to the diagram attached (I've quickly painted over to make it clear what I mean). At each roller shutter there is a box into which the switch will come, from there up above the room 3x1.5 goes into the box. From the roller shutter a 4x1.5 goes into the same box and from the box a 7x1.5 goes out to the switchboard. I would like to control the roller shutters in each room with a switch and via an app. Can you recommend a central controller that can do this? Or what is the most sensible solution?

If you have a central control unit, I recommend a PLC solution, or a canned control unit where you are only limited by the remote control range from 1 to 15.

I have decided on the ZAMEL SRW-02M SUPLA.
