Alert electrical power off

Hello everyone.
I have an hub version 2, so if the electrical power of my home is off, the hub uses the backup battery and it doesn’t turn off. However how can I understand if my home’s power is off? I don’t receive any alert.
Thank you

There is no alert for hub lost power at the moment but you should get an alert for no internet connection. Unless.

I’m having the same issue with my V1 hub; power goes out no alert.
I unplugged the hub and it sat for over an hour with no alert.
There’s no alert for internet loss either, but it use to work.
I guess my smartthing has gone dumb as it doesn’t know if it’s even on or not.
