After banging my head against the wall, I figured I’d post here and see if anyone can help. I’ve triple checked wiring, but maybe I missed something.
I have two lighting circuits (one 4-way, one 5-way) with dumb switches that won’t perform as expected and are exhibiting similar behavior. Line and load in separate boxes. Basically, both smart switches (LZW30 and LZW31) are definitely wired to hot + neutral and are definitely powered the whole time. I’m running Home Assistant and used the modified open zwave files, so both switches appear properly in HA.
If the smart switches are on, the remaining 2/3 switches work as expected (you can toggle them on and off and control the lights). However, if you toggle off using the dumb switch, the smart switch remains in an on state, but the lights go off. Similarly, if you toggle off with the smart switch, the dumb switches won’t work.
It’s as if the smart switch is acting as a SPST switch and ignoring the traveler. This does not strike me as a wiring issue, but a switch config issue, but I can’t find any setting that works? Setting switch type on the LZW31 to “3-way toggle” does not fix it (and the LZW30 apparently doesn’t have that setting? So maybe I have some funky wiring setup that isn’t obvious to me? (my first home, though I’m generally electrically/electronically capable).
