Because of the recent Somfy issue, I had to unlink Homey from Google Home (my cover devices would not sync anymore with Google Home).
Before doing so, everythings was working fine.
When trying to relink Homey to Google Home, I get an error “Parameter cannot be modified. Check your connection”.
This error appear a few seconds after selecting my Homey account.
If I check security settings in my google account, the link appear. However in Google Home, the “service” doesn’t appear in the list of services.
And no device appear.
If asking to sync devices, nothing. Google Home is not even aware is it linked to Homey.
I tried unlink/relink with my reolink account (cameras), and it works perfectly.
I also tried with a different phone, a diffenret google account, same error.
I even deleted the whole house from google home to redo everything.
It seems like the link is blocked on “homey” side.
Any got advices/ideas ? I opened a ticket to Athom support about it.
