Configuration FLOW is not clear

[arpel]

Hi !
Just tried to configure after seeing the depreciation message on residential_altherma integration.

I logged in to the developper site and went to the "Getting Started" page with the Spring credentials.
I just copy/paste them into the config flow of the integration within HA (yet "Name" was invented at the time).

It simply fails with "Error" while redirecting to the developper site, and the message is :
https://id.daikin.eu/b2c-oidc/eu/en/error.html?mode=error&message=The%2Bredirect%2BURI%2Bin%2Bthe%2Brequest%3A%2Bhttps%3A%2F%2F[my hostname]%2Fauth%2Fexternal%2Fcallback%2Bdid%2Bnot%2Bmatch%2Ba%2Bregistered%2Bredirect%2BURI.&code=invalid_request&skipConsent=false

Could you help ?

Thanks !

The problem is very likely that you have my hostname as custom redirect uri in your HA setup which Daikin doesn't support yet, see #45 for a similar issue, that contains some links that maybe can help.

Ok, thanks for the confirmation and the hint : it just felt I missed something.

To make it work (which it is finally) I had to add an empty my: to the configuration.yaml and add a local dns entry for homeassistant.local (not by default as running "Core" only).

Thanks !

Finally, linked to #62 , it seems that this "my hostname" needs to be kept empty after initial configuration for the token refresh to work.

In my case that's an issue as having "my hostname" empty seems to break the mbapi2020 (Mercedes Me) custom integration.
