Hi, I recently purchased 4 Red Series dimmers and successfully installed 3 of the 4 (2 used in different 3-way scenarios and 1 used in a neutral-less 2-way scenario). Those are working just fine.
However, for the 4th one, I am having issues getting it to work. When I first turn on power to the dimmer, the LED immediately cycles from Red to Green to Blue to off. Then the light(s) slowly ramps on to full power as expected. The LED then shows blue, as it would when the lights are on, but none of the buttons work no matter how long I hold them or how many times I press them. The dimmer is otherwise unresponsive.
At first I was installing in a known working 3-way scenario that was using dumb switches. If I cycle the dumb-switch, the lights turn off and on. So after confirming all the wiring was correct, I decided to remove the second/remote dumb switch and install as a 2-way only. Same behavior.
So then I got out my test board, which is basically just an electrical box screwed onto a board with wiring to a light socket also screwed onto the board. Then it has an extension cord with one end cut off and the other end with the male socket to plug into an electrical outlet. I usually use this to pair devices that may be too far away from my hub.
After testing in here, I noticed the exact same behavior. If I pull the air gap, the light turns off and so does the LED (as expected). When I push the air gap back in, it starts the cycle again with the Red, Green and then Blue.
For giggles, I also tried adding an Aeotec bypass to rule out it being an LED bulb, but that shouldn’t have an impact since neutral is being used as far as I know.
I’m stumped here. Does anyone have any idea what could be causing this and/or how to fix it?
