It has worked fine until now. When I check the sensor, it does not have any values. It seems like it cant get any information from the nordpool internet source.

What currency are you using and price zone? Please use the issue template, it’s there for a reason.

I get the same error. Sensor config:

- platform: nordpool
  VAT: True
  currency: "NOK"
  region: "Oslo"
  precision: 3 
  price_type: kWh

Failed at about 19.00 CET on several platforms (2 x rpi4 + 1 x nuc i5).

Seems like a nordpool issue. The site also just list the prices in EUR.

[TomTorger]

Yup, found the bug reported in the underlying package:
kipe/nordpool#21

I see the same issue. Is it related to the Nordpool Currency (EUR) issue ?. For some people it seems to work, for others it still fails after several restarts. When it works there is a Warning in the log that the Integrations takes too long time to setup. "Please contact the developer of the integration"

[Hellowlol]

@oivindklausen I dont know. My sensor work just fine, the problem is that the data from nordpool dont return the correct currency (some times?). So instead of returning the incorrect currency a exception is raised. About the setup is slow depends on how quick the nordpool api responds.

[Hellowlol]

@oivindklausen Can you share you nordpool settings?

[oivindklausen]

The integration is only setup from the GUI. These are the current States Attributes (When the integration is working). I think the unit was øre/kWh when it was not working. However, I have not touched these settings and the Integration has been rock solid until the now. After several restarts (Yesterday and Today) both my installations now seems to work. (Home Assistant OS 5.13, core-2021.4.4, supervisor-2021.04.0). This issue has also been discussed in the Norwegain Facebook group.
