Similar situation, but, in trying everything I can to get my HomePod Minis to re- connect after they fell off, I removed them from home. I have reset them dozens of times, and I cannot get them to pair again... different iTunes accounts (within home/family) multiple networks, multiple iPhones, multiple iPads, various states of b e t a on the various devices, as far back as an IPhone SE on no b e t a and they never pair...

I wonder if downgrading them to non-b e t a, using a non-b e t a device to add them to home would do any different?

The only thing I haven't done, else, is delete my home, but I am apprehensive of starting that far over...

Open to suggestions... Thanks!

When trying to restore, "The resource is not available" is the message i get, device will not restore, or add to Home. Multiple attempts.

Reboot your router and try again. Contact Official Apple Support for assistance.
