This is a message I just sent to support. I thought I would post it here in case anyone has any ideas:
I have been having Zigbee issues for about a month now. I opened a ticket about this earlier.
The issues I am experiencing are affecting a version 2 hub.
Here is what happens.
About a month ago, 6 of my GE wink bulbs (4 regular bulbs, 2 floods) all came on for no reason in the middle of the day. And smart things would not control them.
At the same time that happened several other Zigbee devices stopped working, including:
Smart Things Motion sensor
Lowes Iris 2 Motion Sensor
Eventually, the other zigbee devices started working, but the bulbs never came back.
So, one day I reset each bulb and then added it back. The weird thing is that when I added it back, it went back where it was. For example, when I added the Deck bulb back in, and then went to things and taped the deck on and off it worked.
A few hours later, all the bulbs came back on and my other zigbee devices stopped working. I turned off the bulbs rebooted the hub, and eventually the devices started working again, but the bulbs did not.
So, today, I reset the first bulb and then searched for it. The bulb flashed as if it had been found by the hub, but the app kept spinning like it didn’t find anything. I turned on the next bulb and it immediately flashed as if it had been paired. I turned them all back on one-by-one and each one flashed and I could control them from smart things.
About 2 hours, later, they all came on and now my zigbee devices are not working again.
I have turned all the bulbs off and I just unplugged both cables from the hub and removed the batteries and then put the batteries back and plugged it back in. My motion sensors still do not work. The Smart Things motion says it detects motion, but when I look at Recently, the last update was almost 6 hours ago.
What is going on with these devices? Why are they messing up the Zigbee control?
Anyone have any ideas?
