I’ve got a GE Link bulb in my hallway that’s setup to turn on w/ a ST motion sensor, and I’ve been fighting with it for a couple months now. It’s connected via the ST Hub. It seems to work consistently for hours at a time, but then very inconsistently or not at all for hours/days. I’ve tried different SmartLighting schedules/bulbs/SmartApp vs. Routines over the past several weeks with no luck. The logs show that the motion sensor is working, and the bulb log shows triggering by the app/routine, but it’s just not turning on 50-75% of the time.
I have wireless devices of all types in my home, and not too many repeating Zigbee devices (besides more Link bulbs), so I can’t rule out interference/connectivity issues - especially since it’s a bulb inside a metal can ceiling fixture. But the weird thing is that it’s 100% responsive if I pull out my phone and push the On/Off button within the Things page.
