I need help, i have gone through all the steps in this guide: https://www.home-assistant.io/components/google_assistant/
I link the account in my google home app on the phone and it seems to work fine ( i log in on the hassio screen appearing).
But when i tell google home to sync it tells me:
“An error occured when syncing my test app”
you went all the way and setup the homegraph and added the api to the config?
Yes, so i have repeated the process numerous times and set up several projects.
Each time i can “add” the test app in the Home app and with my iphone it seems to link the account or at least says so.
However when i ask the Google home mini to “sync my devices” it says “it looks like you dont have any devices supporting syncing”
Im clueless as of now
I find every so often I lose this ability and have to remove and re-add the app through the Google Assistant app, but only after I run the draft Test each time. Quite annoying…
It’s the price you pay for the free integration. Google disables the test app from time-to-time. I usually only need to re-enable testing and it works again without relinking.
Ahh I see, thanks for elaborating.
Had a similar problem and found this topic just before posting a question. In the end I got it solved by unlinking and linking again… Here was the text I was going to post, just for reference as it might help others find this topic.
I added some new device to my home assistant setup and wanted to do a “reload devices” on the google assistant to be able to use the google home to voice-command my setup. Previously that always worked and when I give commands to google home for the “old” devices, everything works fine.
When I enter “reload devices” in the google assistant chat I always get the response “Sorry, an error occurred while syncing mr. Pippin”. Any idea why that stopped working?
So, the solution as proposed by @DavidFW1960 and @talondnb works!
