# Go-eCharger Binding
This Binding controls and reads data from the Go-eCharger (opens new window). It is a mobile wallbox for charging EVs and has an open REST API for reading data and configuration.
# Supported Things
This binding supports Go-eCharger HOME+ with 7.4kW or 22kW.
# Thing Configuration
The thing has two configuration parameters:
| Parameter | Description | Required |
|---|---|---|
| ip | The IP-address of your Go-eCharger | yes |
| refreshInterval | Interval to read data, default 5 (in seconds) | no |
# Channels
Currently available channels are

# Setting charge current of Go-eCharger based on photovoltaik output
You can easily define rules to charge with PV power alone. Here is a simple sample how such a rule could look like:
rule "Set max amps for PV charging"
when
Item availablePVCurrent received update
then
logInfo("Amps available: ", receivedCommand.state)
MaxAmpere.sendCommand(receivedCommand.state)
end
You can also define more advanced rules if you have multiple cars that charge with a different amount of phases.
For example if your car charges on one phase only, you can set maxAmps to output of PV power, if your car charges on two phases you can set maxAmps to pv output / 2, and for 3 phases pv output / 3.
In general the calculation would be ´maxAmps = pvOutput / phases`.
