I don't believe this is a wiring issue, I'm an electrician. I installed these dimmers on a job yesterday. I've never come across an issue like this. The dimmer with the issue controls 3 WAC lotus 4" wafer leds and 2 WAC 4" pop in leds. The 2nd dimmer controls vanity sconces and the 3rd is a 3way with a companion dimmer that controls 2 WAC lotus 4" wafer leds & 1 WAC 4" pop in led without any issues. It seems like the 1st dimmer only turns on when I hit the 3rd dimmer. I did swap dimmer 1 & 2 to see if the dimmer was bad and had the same result. I could not figure out how to post the video here. Any help will be greatly appreciated. https://www.youtube.com/watch?v=skfp...ature=youtu.be
