EVCC

Chargers, vehicles, solar, grid and dynamic prices from evcc, with its charge modes.

In a dashboard file: a connection with "driver": "evcc", its settings in config, and what a data source of it reads in that data source’s params (Connections and data sources).

Example

A dashboard with a connection of this driver, named evcc, and a tile that reads it. Any number of tiles can read the same connection. In the editor, the values of params are picked from what the connection lists; ids in the example are made up.
