I pull in market prices via entso-e and have those used in my energy configuration. When I look at the graph the hourly rates correspond with my energy suppliers information. But somehow since probably two beta versions of home assistant the cost calculation goes very wonky.
I’m guessing you’re asking about Tariff 2, but you’ve apparently just shared me the details for Tariff 1, for which everything looks normal as far as I can tell.
The CSV would give more details but it’s restricted, I can’t see it.
It will tell you which cost entities have been created for each tariff, would suggest look at what is the id of the cost entity, and you can plot it side by side with the consumption in a history graph and get a closer look at how it is behaving.
ok think I am getting there, thanks to your help! I think it has to do with transition from night to day rate. Since not applicable for me anymore, I will see if I can remove this from the P1 integration.
