Suggested Improvement to Reboot "Offline" Hubs that are inaccessible

as a workaround recommend you put a wifi switch behind the st hub and remove the batteries

You are not the only one.

me too. Hub has been offline now for 24 hours. I have not reset it yet, hoping it would come online by itself. Also, we had a storm last few days and my switches turn on immediately after I turn them off. As in all my switches!

Nothing short off remove the battery and unplug the power from the hub will revive it.
