This morning after I updated the HA to 2022.7 my NEST integration failed.
I guessed it was the new update doing this.
So at first I tried to correct the credentials, as I thought that was the problem, that didn’t solve it.
So I tried recreating the ‘Device Access’ Project, that didn’t solve it.
Now I’ve started all over, making very sure that the ID’s for the cloud project, the device access project ID, the oauth ID etc. are absolutely correct.
But I still get the " Can’t link to [Project Name]: Please contact [Project Name] if the issue persists" message as mentioned in the docs.
I’ll leave it for now, going to Berlin in 20 mins, and won’t be back until sunday, where I’ll try and configure it in HA again.
