So I am lucky that almost all my switch locations have a neutral wire, however I have one location that is not.
This location has two light fixtures, with a single bulb each. Each fixture and the switch has a single 3 wire romex. My multimeter shows the white wire is hot at the switch location.
The end goal is to have an illumin color bulb in each light fixture. As such, there is a bypass installed in parallel in one of the light fixtures (one fixture has no bypass).
This all worked well for about a week. However, I woke up one morning to the red dimmer continually boot looping (cycle through the colors on LED notification strip, then go dark and then repeat).
Wondering if the bypass had gone bad, I replaced the illumin bulbs with standard incandescent. However the switch continued to boot loop, and now the incadescents would flash with each loop. I contacted support, and they suggested that I also try halogen incandescents. The behavior was the same, and support fell silent.
After waiting a bit I decided to try another red dimmer from another location. This one behaved slightly different. It would stay power on (with both incadescents and smart bulbs) as long as the level was not set to 100. If you dimmed up to full power with either, the switch would loose power and reboot, then come back on at a lower level.
I then took both red dimmers and created a test setup with a neutral wire. Both dimmers seem to function properly in this setup. Currently the switch location has no switch and is just hardwired on.
Any ideas of what could be going on here? Suggestions on what to do next?
