I am in the US and I have a similar question about my wiring setup and whether a LZW30 On/Off switch is compatible while keeping my dumb switches. But I’m not confident I’ve properly understood which configuration I have given the 3 switches related to my light fixture, so I’m uploading photos:
- Load & Line (Same box?)
- Dumb 2nd switch with 2 black & 2 red wires, no neutral connected (at the moment, though one is capped in the box)
- Dumb switch closest to fixture, as I understand (which also has neutral wires capped in the box):
If I’m accepting of the paddles not always matching the light state, is my Black Series On/Off switch compatible in this 4-way configuration?
I have a voltage tester, which I can use to help guide/troubleshoot but I am struggling to maintain power to the Inovelli switch when operating the other (dumb) paddles. Any help is very much appreciated!
