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”
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.
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?
