In this way, it's really comfortable to control the lamps without trying to find the switches at night :)

I made it with two industrial joysticks bought from a local hardware shop. The signal is going to the electrical rack in my storage room. I'm using two smart relays - Shelly Pro 4PM made by a Bulgarian company. They are enough to control the lights in the whole apartment. I have used several impulse relays by Schneider in the past. They are with better quality but outsourcing the smart logic inside the relay makes the setup easier. Now I have only two FTP cables between the electrical rack and the network rack. They are mounted to the patch panel. Everything is controlled by Home Assistant which is installed on a Raspberry Pi 4 but this is not the topic. The joysticks are not smart. They are used instead of buttons.

This is the electrical DIN rack with the relays

And this is the network rack. They are patched directly on the sockets at right.
