I have HA object nordpool_kwh_lv_eur_4_10_0.
It’s difficult to remember initial setup configurations, I believe the region is LV and the currency is EUR.
Is there a easy way to see configs for the integration?

I found the same error in my logs, for 24 hours. During that time no price information was updated either. After that, it restored itself. I'm guessing some HTTP request sometimes fails, resulting in that None. I'll investigate some more and see if I can track it down further.
