Home Connect integration error

Hello,

I am currently trying to register the application in the Developer Home.

As described, I enter “http://my.home-assistant.io/redirect/oauth” in the redirect ULR
I have also checked that the “http://my.home-assistant.io is redirected correctly.

However, when I try to save the application registration, I get the following error message in the Developer Home: ”The character / is not allowed.”

I would be grateful for any tips!

Best regards
Ralf

Sane here. All this procedure and api seems to be a little … crappy from Home-Connect side.
