Power outages kill all 9 of my hs100’s for a day or two. After the first outage I tried my best to reconnect them to no luck and after a day they all just magically returned back online. Well then our next outage hit and after 2 days they still did not come back so I started messing with one where I held the rest button for 5 seconds and then connected to its WiFi and that hs100 went into local only mode - after reconnecting to my home WiFi all the other hs100’s came back online except that one I messed with - now it’s stuck in local only mode and nothing I do gets it out. What’s the deal?
