# Keba Binding
This binding integrates the Keba KeContact EV Charging Stations (opens new window).
# Supported Things
The Keba KeContact P20 and P30 stations which are providing the UDP interface (P20 LSA+ socket, P30 c-series and x-series or BMW wallbox) are supported by this binding, the thing type id is kecontact.
# Thing Configuration
The Keba KeContact P20/30 requires the IP address as the configuration parameter ipAddress.
Optionally, a refresh interval (in seconds) can be defined as parameter refreshInterval that defines the polling of values from the charging station.
# Channels
All devices support the following channels:

# Troubleshooting
# Enable Verbose Logging
Enable DEBUG or TRACE (even more verbose) logging for the logger named:
org.openhab.binding.keba
If everything is working fine, you see the cyclic reception of report 1, 2 & 3 from the station. The frequency is according to the refreshInterval configuration.
# UDP Ports used
Send port = UDP 7090
The Keba station is the server
Receive port = UDP 7090
This binding is providing the server
UDP port 7090 needs to be available/free on the openHAB server.
In order to enable the UDP port 7090 on the Keba station with full functionality, DIP switch 1.3 must be ON.
With DIP switch 1.3 OFF only ident-data can be read (i and report 1) but not the other reports as well as the commands needed for the write access.
After setting the DIP switch, you need to power OFF and ON the station. SW-reset via WebGUI seems not to be sufficient in order to apply the new configuration.
The right configuration can be validated as follows:
- WebGUI DSW Settings:
DIP 1.3 | ON | UDP interface (SmartHome)
- UDP response of
report 1:DIP-Sw10x20Bit is set (enable at leastDEBUGlog-level for the binding)
