Self healing?

I have a Pi4 running 2021.3.0 with a Conbee II and the deCONZ integration.

Most of the time it’s faultless across about 50 devices. But once a week or so one device will just decide not to play any more. I do nothing and the device will just start working a few hours later.

I’m assuming that it’s healing itself to find a new route back to the coordinator.

I don’t have a problem with that unless it’s one of the bedroom lights and, obviously, trying to go to sleep with a light on isn’t realistic so I have to kill the power on the device, turn it on the next morning and wait.

Is my assumption about it self-healing realistic? And is there a way to speed this up or force it to happen?
