Additional context

[magiva]

this happens when network connectivity drops, my asus mesh node loses connection to the base router for a moment, all other devices recover but zha and zig2mqtt does not

[magiva]

the zha bug ticket is here if you want that for reference, like i say, the only thing not to recover is zigbee intergration with zha and this zg2mqtt addon
