I followed this and paid the $5 USD to integrate Google Nest. After many clicks and many pages it seems I have linked it all well but in dashboard I see “Unavailable” for Humidity and Temperature.
I did the following as per troubleshooting guide:
- I restarted the Nest and it didn’t help.
- I did Reload of the device in HaOS and it didn’t help.
- I changed the room for the Nest from Basement to Attic in Nest app and it didn’t help.
Things to note:
1- I can not login to https://home.nest.com/ using my @gmail.com account which is associated with my Nest. I don’t remember if I migrated the account to Nest.com or it is still with @gmail.com account. However, when I try to login using Nest app, it does login using @gmail.com account.
2- My Nest app shows three different Homes. Two have no devices in them and only has. I think I created these Homes before. I am not able to delete them in Nest app. It is asking me to go to Google Home app and in Settings delete these Home but there I can not see them to delete them. Regardless, this may not be the issue.
Where in the whole clustermess of the guide, can I find if the project I created on Google account is actually attached to my only active Nest and not to my old homes which don’t have a Nest any more?
In the logs after all the successful established connections I get these:

I also see this but probably not important:
