Not sure if this is connected, but a new firmware has been pushed to my ST hub. And since it has every section I go to on my app gives errors, I have to keep going back and forth and the error goes away. Is there something wrong in this new firmware?
I had a similar issue were I had to re-sync all of my Samsung door and door sensors.

I had an issue with my hub going offline last evening and tonight. Yesterday came back after a reboot of the modem. Tonight I took the batteries out, unplugged power/ethernet cable for about a half hour. It came backup after that.
Is your Hub light Orange? If so:
