@rbrunka Could you take a look at this?

I’ll try to prepare a PR for the Pstryk template, but I need help with building and testing it. It looks like only a small change is needed: updating the endpoint URL and fixing the jq logic.

Instead of using plan to switch between endpoints, we should use a single unified-metrics endpoint and distinguish between energy purchase and feed-in prices based on different properties in the response.

No need for help - I updated tariff template, tested with newest evcc binary and it works.
