# evcc Binding

This binding integrates evcc - electric vehicle charging control (opens new window), a project that provides a control center for electric vehicle charging.

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.

# Channels

# General channels

Those channels exist only once. Please note that some of them are only available when evcc is properly configured.

Channel Type Read/Write Description
general#batteryPower Number:Power R Current power from battery.
general#batterySoC Number:Dimensionless R Current State of Charge of battery.
general#batteryPrioritySoC Number:Dimensionless R State of State of Charge for which the battery has priority over charging the ev when charging mode is "pv".
general#gridPower Number:Power R Current power from grid (negative means feed-in)
general#homePower Number:Power R Current power taken by home.
general#pvPower Number:Power R Current power from photovoltaik.

# Loadpoint channels

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