I have made an observation that I hope I can get some assistance with. I have a handful of GE Zigbee dimmers and GE Z-Wave dimmers. I setup a Simple Lighting routine to 'Turn On & Set Level' of the GE Zigbee dimmer but the lights never turn on. Running the same routine with a Z-Wave dimmer works exactly as expected
Simple Lighting Routine:
Virtual Switch: Studying
GE Zigbee Dimmer: Living Room Lights
Routine: Turn On & Set Level Living Room Lights when Studying turns on
I'm having this issue as well, with my Zigbee GE dimmers, and with my Sylvania Zigbee light bulbs. My GE Z wave dimmers allow turn on and set level without issue. The bulbs fail to light virtually every time I try to set a value of less than 100, and interestingly often report as being on and operating. The GE Zigbee switches only seem to have issues intermittently. In my case, the GE dimmers seem to want to route through my bulbs, making it appear the bulbs might be the issue. I'll have a lot of downtime in a couple of weeks and plan to connect my ST hub to the HE one and put the bulbs on the ST hub to see if that resolves the issue.
I have over 40 Sylvania color bulbs and 2 of the GE zigbee dimmers. I had initially added turn on in the rules for the bulbs, because after I made the rules the bulbs didn’t come on. I later noticed that if I waited a while before trying the automation, it would work without the “on” command. I have subsequently removed the “on” command from the dimmer rules without issue. My GE dimmers route through the hub usually, although I have seen one route through one of my peanut or Samsung plugs. They were having the same issue described here, so I put them in RM.
Looks like we got some traction here! The latest Hubitat Live on YouTube mentioned a fix for Zigbee dimmers with the 2.1.4 update. Just updated and I am please to say that my GE Zigbee Dimmers are turning on with dimmer adjustments (Turn On & Set Level).
