yes I get the same error, have tried multiple earlier versions of haos and other viersions of nordpool but nothing seems to work. any ideas woulld be greatly appreciated

[JeppeDegnbol]

figured it out its a change recently that asks for integration that is not there, was able to change config_flow to fix.

[VeliKoskinen]

Easiest is just to install v. 2.2.0 and do the configuration with that

[alesecurity]

@JeppeDegnbol I got it working with 2.2.0 also, just a simple downgrade did the trick as @VeliKoskinen pointed out.

[Trihawk-8]

I ran into the same issue on a recent Home Assistant version.

I tracked the problem to config_flow.py and submitted a pull request that fixes the 500 error by discovering the Nord Pool sensor entities directly from the Home Assistant state registry.
