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.
Or flash it. Or even use it with the stock firmwhere but firewall off from the Internet so you can only control it with something like the web interface or home assistant.
