I’ve wired my LZW30 in 4 way box load/lead and it looks just like the wiring diagram provided by Inovelli. Yet it won’t work.
So I swapped the switch in another working 3 way circuit (I’ve got 4 working perfectly), and it works perfectly. So it doesn’t look like a switch problem.
I reinstalled my old toggle 3 way switch into the 4 way circuit, and it worked perfectly.
I took the known working switch taken out of the above circuit and installed it into the 4 way. Didn’t work.
To reiterate, my setup looks just like the diagram for the 4 way in a box with line and power in the same box.
The only way to make the switch work in the circuit is to switch the black line wire and the white line wire. Then the switch will work if I have the other 2 switches off. If I flip one of the dumb switches, power is removed from the smart switch as “incorrectly” wired (white for black, black for white).
Please, any help would be appreciated.
