I go to a half-way house: Smart bulbs, dumb switches, but a zigbee button next to the switch.
1 click toggles on/off in the last state.
Press+Hold for warm-white evening.
Double-click for daytime.
And now, a sticker on the 230v switch that says “don’t switch off!”







I have the ecowitt wh51, directly with rtl_433.
It’s the 866 version.
I had to set rtl_433 to also monitor 866, but other than that, it’s been very solid for…Blimey, years now.
