In wall light switch node - Custom PCB
-
In Germany and also in Belgium a lot of house installations have been built with pulse relays and 0-10V dimmers in a central switch box and only 12V controls to the switches. Makes for a bit more work when building the home (conduit from the fusebox to all seperate switch boxes) but changes during the lifetime are a breeze.

@DavidZH - I have to be honest here. I would love it if we did this in the UK. I wouldn't be scratching my head about how to fit a double relay board behind a light switch. I really do wish we had low voltage at human accessible point through-out the house, rather than switch 240V inside of a light switch.
Out of interest, is this 12V in your switches DC or AC?
Also, this is the relay board that i have just published. Development work to be done a little further though. https://www.openhardware.io/view/345/Homini-AC-Powered-Relay-2-Module

As far as I know the power to the switches is AC. Only a simple transformer, and Bob your uncle. They do also work on DC, as they only use a short pulse to change state.
Here in NL only a handful have an installation like that. I am most certainly not opposed to it, but most houses over here do not have room for a huge switch box needed for such an installation. And another plus is that those relays can stay and you only have to add your domotica controls to the panel. Only difficult thing is the feedback to the controller of the state. You'd have to add auxilary contacts, or measure the live wire.I do not have a system like this but was just explaining what Artipi has.
And I think there are some other things in the UK electrical system that need te be dead and buried in a hurry. Like the 32A ring circuit.... 😣

@DavidZH - I really hate our electrical system here, but that is coming from an electronics guy, not a electrician. I like the idea of low voltage in the switches, however its AC. I would prefer to see DC, but the voltage drops might be something that they're attempting to avoid by sending AC instead. Yes, i agree about those damn rings and we also don't have the room here in the UK like you mentioned about the NL.
