 # 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 0.123.1](https://github.com/evcc-io/evcc/releases/tag/0.123.1) or newer and is tested with this version.
+The binding is compatbile to evcc starting with [version 0.123.1](https://github.com/evcc-io/evcc/releases/tag/0.123.1) or newer. Starting with [evcc version 0.125.0](https://github.com/evcc-io/evcc/releases/tag/0.125.0) this version of the binding is mandatory as some of the evcc rest-API parameters got discontinued. This binding was tested with [version 0.125.0](https://github.com/evcc-io/evcc/releases/tag/0.125.0).
 
 You can easily install and upgrade evcc on openHABian using `sudo openhabian-config`.
