 In general, due to the minimum value of 5% for signalling the EV duty cycle, the charger cannot limit the current to below 6A. If the available power calculation demands a limit less than 6A, handling depends on the charge mode. In **PV** mode, the charger will be disabled until available PV power supports charging with at least 6A. In **Min + PV** mode, charging will continue at minimum current of 6A and charge current will be raised as PV power becomes available again.
 
-### PV generator setup
+### Meter setup
 
 For both PV modes, EVCC needs to assess how much residual PV power is available at the grid connection point and how much power the charger actually uses. Various methods are implemented to obtain this information, with different degrees of accuracy.

-EVCC can be used to remote control an openWB charger using openWB's MQTT interface. Here is an example for how to use the `default` charger for controlling the first loadpoint, using the special `openw` plugin:
-
-````yaml

+#### KEBA preparation
+
+KEBA chargers require UDP function to be enabled with DIP switch 1.3 = `ON`, see KEBA installation manual.
+
+If using Docker, make sure that the Docker container can receive UDP messages on port 7090 used by KEBA by using [host networking](https://docs.docker.com/network/host/) in Docker:
+
+```sh
+docker run --network=host -p 7070:7070 andig/evcc ...
