Daniel Reitz enhanced the evcc-io/evcc repository by improving the configurability of the Solarprognose Tariff API. He removed the default mosmix algorithm from the tariff definition, allowing the algorithm parameter in the API request URI to be optional. This change enables users to specify an algorithm or rely on the API’s default, increasing flexibility while maintaining backward compatibility for existing clients. Daniel’s work focused on configuration using yaml, ensuring minimal risk by isolating the impact to API parameter handling. The update streamlines integration with Solarprognose.de and reduces setup friction, reflecting a targeted and well-scoped engineering contribution within the project.
