Device not connecting to app after power outage

Hi there, we have an original Google Nest Thermometer that has worked well for more than a couple years.


We had a power outage last night and while the device did have a fully charged battery, it was dead this morning.
Power was restored later in the afternoon and the Nest came back on when the Furnace did (four wires to furnace provide power).


We noticed soon after that Nest was not connected to WiFi. So I gave it a simple reset. It did not reconnect to WiFi.
I could not get into the Network menu to try to re-enter the PSK (nothing would happen when I would "ring" over to Network and push the button... 

So we gave it a COMPLETE reset and removed the device from Google Home. 

 

It came back just fine after its complete reset, and now connects to the WiFi again.. but Google Home cannot discover it. 

I have tried from my iPhone and from my Android phone, from my wife's Pixel, a Samsung tablet, and our iPad. All of these devices have our Google Home on it and all other devices (several nest speakers, smart lights, nest mini, etc) all work just fine. 

So we've tried to add the device (nothing can "discover" the thermostat, and i've noticed before that new devices appear in the home screen of Google Home in a bubble on top, something like "set up Nest thermostat" etc - that does not happen here... ) - we have tried to ADD the device by typing in the code (some devices get to the "select your serial number screen, some don't even get that far, all fail), we have tried by scanning the QR code (on all devices, we can scan the QR code) and the app just dumps you to the Google Home "home screen" once the QR code is scanned.

 

It's like there's a "ghost" (not visible) device that is somehow "still in Google Home" somewhere that I cannot see, cannot delete, and is preventing us from re-discovering the device.

I've tried everything I can think of and can't get past this. Google Home is up to date on all the devices. The thermostat is connected to WiFi and has an IP in the same subnet, same wireless network, and it can go out and check for new firmware via the "Update" setting (it's at the most recent firmware).


It seems to work as a stand-alone HVAC control but is now completely unlinked from the app and the only way to control it is via the front panel. 

Any help? should we just dumpster it and get a new one?
Thanks-

I've done a complete factory reset twice now, same story - can't connect this device to the Google Home app at all. 😕
