Authentification Error

[FlavorFx]

Alexander, I installed your node red node for home connect. After installation I setup the auth node, enter client ID, secret and URL and started the authentication. I agreed to let HC access to my data and received this failure.

Missing code or state parameter in https://<ip-address>:8123/auth/external/callback code=xxxxxxxxxxx&grant_type=authorization_code

Did I miss something?

[alexkn]

I don't know where this "/auth/external/callback" in your callback URL came from.
It should look like this:
http://<ip-address>:<port>/homeconnect/auth/callback

[FlavorFx]

Thanks for your reply. Ok I changed the URL and i got an authorization code. But there is not Oauth2 Node.

This is my installation:

What's wrong?

[alexkn]

The auth node is only a config node, it is not visible in the flow diagram.
After authorization you have to save and deploy.
If it is still not connecting, check the logs.

[FlavorFx]

Ok, I understand. This is my call back URL:

http://hassio.XYZ.myfritz.net:8123/homeconnect/auth/callback?code=eyJ4Ly_XYZ_In0%3D&grant_type=authorization_code

And this is my log:

The log does not give me an indication. To you?

[alexkn]

Sorry, I can not really help you.
I don't know if there are problems when running Node-RED with Home Assistant / hassio.

Home Assistant also has it's own Home Connect integration.
https://www.home-assistant.io/integrations/home_connect/
It looks like you mixed up the configuration.
