@harjms, @Bry I spent a couple hours tonight testing a variety of configurations out.
I pulled switch 3 and switch 2 out of the equation. I factory reset the LZW31 and rewired it for a non-neutral setup. Everything worked fine with the factory reset LZW31. I was able to turn the light, off, on, and dim. I thought this was odd as I never set parameter 21 to reflect a non-neutral setup.
Next I wired in switch 2, NOT having changed parameter 21 or 22. The LZW31 worked fine but switch 2 has no affect. I set parameter 22 to 2 using the switch (13 clicks, 1 up). Switch 2 now worked to dim and turn off the light. If I set the dimmer all the way up to 99 via the AUX switch, it no longer works to dim or off. If I go the LZW31 and dim the light or turn it off, the AUX switch works again.
Knowing that something was working as expected I wired back in switch 3. Same result, switch 2 and now 3 worked to dim the light, turn off, turn on. Only issue is if I use switch 2 or switch 3 to go to full brightness they stop working.
At this point I paired the LZW31 to hubitat and confirmed parameter 21 = 1 and 22 = 2.
I’m not sure if its a bug in firmware 1.48 but parameter 21 is not having the desired impact.
I still have the issue if I go to full brightness the AUX switches stop working. Is this a limitation of the wattage? I’m using 6 x 60w bulbs, 360w incandescent total. If my lights goes above 70 the AUX switches become unresponsive. For now I’ve set my max brightness to 65 via parameter 6 to keep them below the threshold.
Any idea whats going on at this point? Do you think lower wattage bulbs (30w) would make a difference? Any idea what’s up with parameter 21?
Appreciate the help.
