My Nest devices were removed from Google Home, and they cannot be added back

[tcsellars]

Approximately 5 weeks ago, I noticed my Nest devices were gone from my Google Home App. I logged into Nest, and seen that my devices were gone there too. Nest was asking to do a Home Setup, but it would not connect with my home setup in Google Home. It would either just errantly go back to the previous screen, or throw an error stating that I can't connect to the Nest Service right now. It appears that something in Nest or Google Home has been corrupted with my home setup. If I setup a new home in Nest, I can add my Nest devices to that, but then I'll have two homes in Google Home. I could delete my home in Google Home and start over, but it would be a serious pain in the butt to re-add my 30 devices. Has anyone seen this problem and managed to remedy it?

Thanks

Since inadvertently using a different Google Account could yield the same results, are you absolutely sure that you are logging into the Google Home app and the Google Nest app with the same Google Account and accessing the same Google Nest "home/structure" you were previously using?

Has anything changed with your Wi-Fi network?

If you are using the same Google Account and the same Wi-Fi network, you could try contacting Support to see if they can check the status of your Google Nest "home/structure" on your Google Account to determine whether something is wrong:

1. Go to https://support.google.com/googlenest/gethelp.
2. Select a category/product family, and type in a brief description of the issue, then click "Next".
3. Click "Other", then click "Next step".
4. Under "Resources", just click "Next step". (Clicking one of the listed links will bring up a Help page page.)
5. Under "Contact options", choose to get a phone call or chat with the team, depending on availability in your country.
