I have a problem with one of my Zigbee high-current power relays. Occasionally it enters a state where it reports in several times a second as shown in the video below:
Cutting the power fixes the problem, but it does come back. I think I’ve seen it in multiple different devices, but it is rare so I can’t be sure.
It appears to be causing some instability in the network, with longs delays on commands being issued to some devices; presumably ones that share the same routes.
