I’m in the US. My wife and I are moving into a new-build community in Feb. next year and they are using these wall controls for the rooms with lights and a fan.
I’m having a little trouble finding a home assistant compatible replacement. The 1-gang width probably limits my options severely. I’m open to converting these to 2-gang, so I’m open to 2-gang devices as well.
Zigbee is is my preference, then WiFi (local only), and I’m not interested in z-wave.
That’s totally fair. In my case I was also limited because the location originally had just lights (so only hot+neutral+ground) but if you want to control lights+fan separately you need at least 3 wires+ground (common neutral, shared ground, hot for fan, hot for light).
In your case, maybe something like the Treatlife DS03 might do the job? I’ve never used it myself but it does have separate wires for load and fan-load, there’s a Tasmota template, and still did a fairly decent write-up
