All my Zigbee devices are now disconnected (22 Oct 2022)

[tipton]

I still don’t fully understand what is going on with these Smartthings changes. My zwave devices are all still working fine, but this week all my Zigbee devices are all offline.

I"ve tried all the normal things of unplugging the hub and plugging back in after awhile, removing batteries from my zigbee devices etc and nothing seems to work.

do all these devices need to be deleted and re-added? i’m mostly concerned about all my Ikea blinds

Interesting/odd behavior after Thread firmware update on v3 hub

Some background: I have a v3 hub with a mix of Z-Wave and ZigBee devices. The ZigBee are mostly Sengled and OSRAM/Sylvania bulbs, and a generic motion sensor as well. My hub did the recent firmware update that enabled the Thread system. I was reading in another forum a comment about this that said we could check in the app that Thread was present and see info about it on our hubs. In my app, on my hub, I saw no such info even though my hub was showing the correct firmware. So, I rebooted the hub, and then in the app I could see the Thread info as reported. However, from then on my ZigBee devices (the bulbs) started behaving weird. The motion sensor went offline and I could not get it back on. My ZigBee bulbs were randomly turning on and I couldn’t turn them off from the app nor via…

Otherwise, you may need to contact support.
