Problem with Home Connect

I try to add Home Connect integrations: Home Connect - Home Assistant

After final linking step i got “Error” and in the log is error below. I dont understand what is wrong and i did not found option how to remove this uncompleted integration. How can i remove it? I don’t see it in UI and file system as well.

2023-02-09 17:15:02.251 DEBUG (MainThread) [homeassistant.helpers.config_entry_oauth2_flow] Token request failed with status=400, body={
“error”: “invalid_client”,
“error_description”: “client has limited user list - user not assigned to client”
}

For me this was the solution:

My SingleKeyID email was created with a capital. Changing the email to a second emailadress and then back to my first emailaddress but with lower case letters only resolved my problem.

Via Settings > Devices & Services > three dots menu in the upper right > Application Credentials, you can remove the credentials used and start fresh.

From what I have read, these are the tips:

  • The SingleKeyID needs to be all lowercase letters.
  • Redirect URI should be https://my.home-assistant.io/redirect/oauth as stated on Home Connect - Home Assistant
  • It might take a little time for Home Connect to set your app credentials, so go for a coffee break once saved.
  • You may need to be logged out from the Home Connect developer site.
  • Some people report that using a different browser of a private browsing window helps as well.

I don’t understand all of these tips, though.

Thanks Mirjam. SingleKeyId e-mail address was the problem: https://singlekey-id.com/
