I had previously installed the Commercial Electric 6" LED recessed lights with “night light” feature and just recently installed and set up LZW31 and LZW31-SN switches to replace the old toggle switches.
Bad idea, not only do they buzz, but they get out of sync, so some will be on and others will be in nightlight mode. It seems like turning off the switch doesn’t quite turn off the circuit, if I use the air-gap then it will reset them, but then they get out of sync again. They didn’t do this with the toggle switches.
Anyway, I have 14 of them in 2 circuits, so I figured I’d do some research. I actually got them at Home Depot, so I checked their website and lo-and-behold, similar complaints in the comments:
Anyway, seems like someone with the same problem with a Lutron Caseta dimmer “solved it” by adding a Lutron load capacitor (part #LUT-MLC).
Is there anything similar to the “Load capacitor” for Innovelli switches? (LZW31/LZW31-SN).
EDIT: I should point out the switches both have neutrals (and are configured so).
