# evcc Binding
This binding integrates [evcc - electric vehicle charging control](https://evcc.io), a project that provides a control center for electric vehicle charging.
The binding requires evcc [version 0.117.0](https://github.com/evcc-io/evcc/releases/tag/0.117.0) or newer and is tested with this version.
You can easily install and upgrade evcc on openHABian using `sudo openhabian-config`.
evcc controls your wallbox(es) with multiple charging modes and allows you to charge your ev with your photovoltaik's excess current.
To provide an intelligent charging control, evcc supports over 30 wallboxes and over 20 energy meters/home energy management systems from many manufacturers as well as electric vehicles from over 20 car manufacturers.
Furthermore, evcc calculates your money savings.
This binding enables openHAB to retrieve status data from your evcc installation and to control the charging process.
For more advanced features like calculated savings, you have to visit the web UI of evcc.
## Supported Things

### Loadpoint channels
Those channels exist per configured loadpoint.
Please note that you have to replace _N_ with your loadpoint number.
