# 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) 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-Sw1
0x20
Bit is set (enable at leastDEBUG
log-level for the binding)
