Power -> can light to -> Switch

Switches Wiring Discussion
#1

Okay so finally figured out part of my 1990’s house wiring. With the trusty multimeter I had assumed that the 3-way that I was changing out was power -> switch -> lamp to 3rd switch. Not really, it is power light switch without neutral…

Once I figured that out I just put a switch on the black/white and confirmed it works. I was happy then I substituted in a LZW31-SN. hm odd then I swapped Load and Line then it started to light the LED bzar and if I press the Config button 2x it will turn green.

I am using the Cree 65w, that is listed on the supported bulb list, I assumed that would mean that even without a neutral in a single switch / bulb it should work. I do have a bypass that I can add to the circuit once I figure out how to pull out the can.

Ideas?

So the problem has been reduced to the dimmer and maybe the bulb. Once I changed out to a different bulb I at least having the bulb working via the SmartThings hub. The dimmer will turn the light on but after that the paddle is useless.

Any ideas???
