I am looking to add home assistant and some automation to my wife’s parents home.
Nearly every light switch is a 2 or 3 gang with a lot of 2-way wiring for various lights.
I am thinking of replacing their light switches with Aqara D1 smart switches but I’m not sure how exactly to wire the two way scenario of the existing switches.
For instance, in their living room, they have a 2-gang switch that controls a light in the living room and the dining room. The dining room has a 3 gang switch that controls the dining room light, an outdoor light and a kitchen light.
If I was to replace both switches, how would I wire this or is it even possible to replicate?
I was looking at Sonoff relays and other brands but the back box on the light switches are quite shallow so the bigger ones won’t fit.
Any advice greatly appreciated, before everything arrives and I attempt to start.
Initially my first thought was, hire an electrician !, but my first “action” would be create a wire-diagram of current installation. Before ! you do anything else
Any help from here would just be based upon assumptions other-vice, in best case !
This is not a specific scenario question, it’s in general, how do you wire 2-way on these smart Zigbee light switches?
Perhaps I just need to wire them like a single switch and then create an automation to change the state of the other switch depending on what happens to the switch that’s changing….
Not possible since it’s not really designed for 2 way switches.
You could just wire it like this and use zigbee binding (assuming it’s supported) or use scene/automation to trigger the other switch
