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
I did the Treatlife DS02S switch by flashing an ESP12F module with ESPHome following the guide here, then swapped the wireless module.
Works well as a normal independent switch with local control from Home Assistant.
Yeah your solution would be the best if I didn’t have fan wiring going to the wall. I wouldn’t want to make the wall switch totally obsolete.
I looked at the Treatlife but apparently they changed the chipset and it’s no longer flashable :/
Ah, those freaking WB3S chips area huge pain in the ass we they’ve been replacing the ESP Tuya on newer models
