Every once in a while I see this warning below with the Nortek HUSBZB Zigbee. But I don’t notice any bad behavior around this time. Should I be worried about this? Anything to do about it? The Zigbee network is extremely small here: just one device and the controller. The device is a Third Reality switch.

This happens less than once a day.
