wow, I didn’t know this. Is it because illuminated switches draw some current when light is off and it fools the smart switch? Can you point me to a thread?
This issue has been resolved by replacing my illuminated dumb 3-way switch by one that is not illuminated. I like to suggest to Inovelli to mention this on the wiring insert that they always include with these type switches. I know I could have found my answer in this community chat vs. making a long thread, but I didn’t know what to search on, and it was only a hunch suspecting it’s due to my illuminated dumb switch I was using with the LZW31.
