Late last night had random zigbee bulbs not responding

In my master bedroom 2 of 4 would not respond. Rebooted hub and that helped one for a couple of cycles and then it would not respond again. Power cycled hub and then all was fine. Is there a consensus of how low memory can get before you should reboot? I was at about 190k free.

This is a C8 that I put into service a few weeks ago. My C7 never had an issue with my Zigbee mesh. The only thing that has changed is some new Z-wave leak detectors and a new router but I put it back on the same channels that it was on before. I did move the Zigbee channel from 20 to 25 when I setup the C8.

C8 at 190K is usually fairly stable. How long had your hub been up at that point?

[tivomaniac]

Can’t say for sure but I’d guess a week?

Okay probably not the issue then. Any power glitches that may have briefly disrupted the hub or one of your zigbee devices?

Night before last power was out for about 1 minute but the hub is on UPS and the lights worked fine in the morning after that. Guess I'll just see if it reoccurs.
