LIFX A19+ Bulb with Red Series Dimmer cannot be turned off via LIFX app (seemingly)

Did you use a LIFX+ bulb (with the built in IR) or a regular LIFX bulb? I am still seeing the issue were the bulb (LIFX+) automatically turns back on to full brightness when trying to turn off or dim to a low level.

Same here with the LIFX+. How do I check that my neutral wire is functioning correctly?

Yes I did and didn’t have any issues with that but then again I have been using our beta FW which is out that you can flash if its the dimmer switch.

I was having the exact same issue with 2 LIFX A19+ Bulbs on a Red Series Dimmer with internal relay disabled. If I turned the bulbs off from the lifx app or my OpenHAB controller they would briefly lose power and then regain power and turn back on.

I just upgraded that switch to the the beta firmware 1.41 and it looks like that has solved the issue for me.
