Thanks Larry and Stu - I will try and see if I can get access to the last can, but these are not remodel lights so didn't see anything obvious when i looked up in there for a way to pull them down without damaging drywall. Is it safe to say that if have disconnected one of the blacks to what I believe to be the last can and it is the only light that goes out, I've found the right one? Another Path: Turns out I have another line and neutral buried back in my box 2 that is on the same breaker. It seems to be a splice of some sort. Could I technically change my setup to a single pole switch by combining Red/Black in Box 2 (capping off the white traveler), wire up Box 1 as Single Pole and power up the Insteon switch in Box 2 using the space Black/White I have in there? Then link the two switches together to be in the same group? I did a simple test using the mechanical switches and it worked as single pole out of box 1 no problem. Any issues doing it this way?

Not sure if this diagram(s) below help, but this is what I believe I have going on. Essentially 14/2 between lights in a continuous cascade, until the last one where the black joins the original 14/3 that goes back down to the last other switch in the circuit. I myself have never wired a 3-way this way, but this seems to work no problem with a regular mechanical switch. Haven't tried a non-smart dimmer, but I assume it would work. Thanks again for the thinking on this.

It's actually 6 can lights in ceiling where I can't get access to the wiring to see how they are wired. Can only go from wiring diagram he provided and assume it's exactly that way. Sounds like I may by out of luck? I hope note. Really would like to use these as intended.

Thanks All for the fast replies -- I'm not certain if my electrician used 14/2 between the lights, but he provide the diagram as to what he did. What I have coming into Box 1 is 14/2 with Black/White (Black is Line / White Neutral), leaving going to the lights is 14/3 (wired as per the diagram). Box 2 just has 14/3 coming into it and connected to a manaul switch like the digram (this one as the white neutral inverted). Hope the helps. I can send pictures of both boxes if that give a better visual as what I have going on. thx!

Hello everyone -- Hope this string is not too stale and the right place to ask, but hoping to find some assistance with getting a pair of 2477d's working on a 3 way. To cut to the chase, my electrician wired two 3-way switches with lights in the middle of the circuit. Diagram attached. For the life of me, I cannot get it to work. When I get close trying a variety of configurations I think are right, they turn on, but I get erratic switch behavior and flickering between turning ON/OFF or dimming. Super frustrating. I have this switches elsewhere in my home, but not 3 way wired like this. Any help or guidance is appreciated. 3waydiag.tiff
