Keba Binding

This binding integrates the Keba KeContact EV Charging Stations.

Supported Things

Currently the Keba KeContact P20 stations are supported by this binding.

Binding Configuration

The binding uses the default UDP port number to connect to the Keba Charging Station. So, no special configuration of the binding itself is required.

Thing Configuration

The Keba KeContact P20 requires the ip address as a configuration value in order for the binding to know where to access it. Optionally, a refresh interval (in seconds) can be defined that steers the polling of the actual state of the charging station In the thing file, this looks e.g. like

Thing keba:kecontactp20:1 [ ipAddress="192.168.0.64", refreshInterval=30 ]

the refreshInterval can optinally be used in combination with autoupdate="false" in the .items file so that the Items are updated with the latest actual value sent by the charging station

Channels

All devices support the following channels (non exhaustive):

| Channel Type ID | Item Type | Description | |-----------------|------------------------|--------------|----------------- |------------- | | state | Number | This channel indicates the current operational state of the wallbox | | maxpresetcurrent | Number | This channel supports adjusting the maximim current the charging station should deliver to the EV | | power | Number | This channel indicates the active power delivered by the charging station | | I1/2/3 | Number | This channel indicates the current for the given phase | | U1/2/3 | Number | This channel indicates the voltage for the given phase |
