This sounds related to the autoupdate update. I’ve seen similar behavior, but when Zigbee devices completely fall off the network and are unresponsive. I do have an ST outlet, and it is working fine, so this shouldn’t be device specific. I’ve also seen this with some dummy switches. This is likely an issue with ESH, or a feature that would need to be incorporated into the bindings.
Do you always have this behavior with this device, or does it clear up after a binding or OH restart?
