Sengled zigbee bulb not accessible in ST

[Barry_Chertov]

If have 2 sengled zigbee bulbs (element color plus) that were working fine for months and just stopped being accessible in ST a couple of days ago. Bulbs still turned on but are not controllable by ST. I’ve tried deleting the devices and re-adding (the QR code on the device was unable to be verified). I’ve tried resetting the bulbs (on/off 10 times) and rebooting my ST hub. No help.

Anybody else having problems or have ideas?

Lots of people having some trouble over the last day or two, it looks like hubs got out of sync with the cloud. The fix seems to be just to reboot the hub, but not from the IDE, you have to physically unplug it. Anyway, see the following:

May 19, 2021 Outage?

Just had all devices stop responding to Alexa, Google, and the app except for lighting groups. Statuses are showing incorrectly as well. Thought I’d ask around to see if I’m alone on this? Nothing on the SmartThings status page as of yet. I always like to check here before rebooting, etc. My hub takes longer than it should to recover after each reboot, so I’m taking it easy on it. Edit: I am in the US Edit 2: Kasa is fine from SmartThings. All Zigbee and Z-Wave dead Edit 3: Smart Lighting to trigger a Zigbee bulb off a Z-Wave door sensor still works. So looks like I’ve got another cloud outage of sorts

Thanks for the rely, JD! Turns out the devices just started working. I did reboot the hub but still wasn’t able to control them even though the IDE showed them as On. However, hours later they started working!
