I have now installed two LZW31-SN switches with GE 46199 Add-On Switches in two different 3-way locations. They are functioning the exact same.
The Inovelli dimmer functions perfectly. I set Parameter 22 to 2 on both. The Add-On Switch “sometimes” works. If I pull the air gap on the Inovelli dimmer, the add-on switch works once, then maybe works again? Then I can’t figure out how it works again, but maybe one out of ten times it will do as I expect.
Are the LZW31-SN’s supposed to work with the GE 46199 or should I have ordered the first gen ones?
