I have a house where I have dumb light switches (eu). I would like something like a relay, that support dimming, that I can place behind the dumb switches. Preferably zigbee. What’s is the best option for this? And is it even possible to add a dimmable relay behind a dumb on off switch? I would think so but I’m no expert.
you might want to look into the Shelly Dimmer 2. It’s a zigbee-compatible smart relay that can be installed behind your existing switches to add dimming functionality. It’s a popular choice for retrofitting smart lighting in homes with existing switches.
That’s Wi-Fi based.
