spamoni covered all the details and said pretty much everything I was going say 
I just wanted to comment to make sure you knew I wasn’t ignoring your call tag to me.
The problem with the hubs not reconnecting on their own is a known issue that Wyze is aware of and working on fixing.
So hopefully Wyze gets that resolved soon so we don’t have that issue anymore. But at least for now, it usually fixes the issue by restarting the hub in the way spamoni posted above. If that doesn’t work for you for some reason, let us know and contact support so they can have a log in their system about it.
