What color is the top right conductor? It looks white to me but It might be because you took the pic with the lights off and a flashlight shining on it. Single switch box, right?
While documentation says it’s not needed, I’m wondering if a bypass might help. Can you get at the wiring box for the pots? Also, possibly updated firmware to get the switch to properly detect the 3-way.
The wire on the top right is white. It is connected to the common terminal on the 3-way switch and yes it is a single gauge box. Getting the the wiring box for the pot light will require remove of some drywall and not sure I am ready for that yet.
Are the pots a retrofit where there is a socket for an incandescent bulb but using a LED via an adapter that screws into the socket? If so, try temporarily swapping out with incandescent lights.
Yes, they are using a retrofit kit. I not sure I have any incandescent bulbs (need to search the spare Bulb Box), I have some CFL bulb I can try. Will post back results once done, may be a day or two.
Looking at the method to update firmware, it does not look like i have the required z-wave USB device for the programming.
Well your suggestion is a big help. I have found some incandescent bulbs and while swamping the LED out with them, I notices that I can remove the pot light figure and gain access. What I found was a hidden junction box.
Not the best view and will need to take more photos to get better angles. (It is a small whole and too much going on to see well)
But what I can see is the pot lights go to this junction box. There is four other wire bundles in the box.
three are the white 3 wire romex cable and one is a black 4 wire romex cable.
The white wire from the pot light is going to the largest group of white cables, the black from the pot light is connect to a white cable on one of the 3 wire romex. the red from the black 4 wire romex is connected to a black wire. So my original wiring diagram is wrong and at this time i have no clue what two romex cables are going to my switches any more and going to need some better photo and maybe get a line tracer out to figure out this mess.
