Any ideas on how to trigger notification when hub unreachable?

When a hub becomes unreachable is there anyway to generate a notification about this? I don’t see anything in the app. I have them connected to Home Assistant and Hubitat but I don’t see any way there (yet) to let me know if a hub is in the unreachable state?

I did notice that when it is in this state, and I send an open/close command from Hubitat, that the device doesn’t update. So I could put a wrapper around the device to make sure it is doing what I asked? But I would have to do that with each device?

I wonder if you automate a reboot of the bond if not reacheable? I image that would get the bond back “online” so to speak.
