I also just tried the workaround described here: [TIP] Gen 2 Dimmer Shutting Off - Possible Solution
It didn’t fix anything. I left my lights on in the dim scene, and they lost power after about 80 minutes.
At steady state, when all the Hue bulbs are off, power is reported as 11w. When all lights are on dim (my “movie” scene), power consumption is reported as 18.5w. After the dimmer cuts power, it reports 4.1w power utilization until I reset things. I don’t know where that 4.1w is going because none of the lights are responsive. As soon as I flip the dimmer off/on again, power returns to normal. The part I don’t understand is why the dimmer is fine when the Hue bulbs are “off” indefinitely, but as soon as I turn them “on” to a dim setting, it acts up. If it was only the low wattage bring a problem, you’d think it’d cut power even when the Hue bulbs are off. Let me know if there’s anything else you’d like me to try.
