Email must contan @.

[molesza]

When trying to add the integration i get an error saying " Email must contain @." I do have an @ sign in my email. Am I doing something dumb here?

This error is currently thrown for all invalid_username errors. It is quite possible that it has nothing to do with the @ sign. Unfortunately, I have not yet been able to reproduce the error in my case.
Probably a daft question, but have you checked several times that the username is the correct one?

I had the same problem but was able to login using another integration: ha-toyota-na. I suppose this is due to the fact that I'm in Canada and that this integration is made for european services.
