Sync errors is normal if you are using the NON cloud version of the Google component, seems the draft version in the simulator is limited in time…
So you need to enable the testing again on the console site
I think you need to do this process every month or something, don’t know the correct time
well, then my problems began
eventually i was able to unlink after a few tries, then delete all the rooms, then i was able to delete the home also
but be carefull, first unshare it on the other phone
because if you remove a home while its shared, then your shared user still sees your home, and unable to delete it, since its is missing on your account, verry strange, but this is a known issue, already have a ticket open for this with google
so my wife is stuck with 2 homes, one of her and one of me, that doesnt excist anymore
What a pain in the xxx, now I redid all from scratch, in the GH app, after clicking link to my test app, it redirects correcxtly to HASS homepage to enter user(password, I do and … I get
“couldn’t update settings check your connection”
I cancelled all my old project, so now I have just one “hassio” project-id.
In the GH app, I do have 2 old “(test) my test app” , they do not go away (projects are deleted in Google console) and the newly (and only one) created for which I gave a different name, now is
“(test) home assistant”
of course I updated my project-id in google_assistant HASS configuration. I ran out of ideas …
yes, they are deleted, but still in a deleting cache in google, it takes about 30 days, until they are really deleted and invisible fro your home app
so if you still have ghost devices of the old app, even its linked and corrupt , you need to wait about 30 days
