Cree Light bulb, Zigbee, did something change in the Zigbee controller in Hubitat? all mine died at the same time

[user1647]

Hi forum.

I had 8 Cree Zigbee light bulb completely go bad all of them suddenly approx. 2 weeks ago (All at the same time!!), I have been running them great up to this point, did anything happen in the hardware update on the platform? or internally? I even tried to roll back firmware (tried 2.3.4.133 even), but that did not solve the issue, Solution was I removed them and replaced them with Sengled instead. (Running current platform on system 2.3.4.139)

Just wanted to ask if anyone know why ALL died same time (what I mean is no response to hubitat commands anymore and cannot be connected or controlled at all.

Best regards
Johan

If rolling back didn't resolve the issue, that likely means the update didn't cause the problem. If you'd like us to further investigate, please send me a private message along with your hub's MAC address.
