## Supported Things
The Keba KeContact P20 and P30 stations are supported by this binding, the thing type id is `kecontact`.
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.

## 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 least `DEBUG` log-level for the binding)
