pls also reword this matter of fact ("current limits must be setup in xyz and can must mirrored in the loadpoint config").

so please ensure to configure

Should be something like "physical charger limits must be mirrored on loadpoint config".

see https://wiki.openwb.de/doku.php?id=openwb:technische-daten:openwb_se. evcc by itself does not enforce these current limits,
so please ensure to configure the maximum current in evcc accordingly.

Additional steps for showing evcc on the display (be careful, because this will allow anybody to enable charging!):
- `apt install labwc wayfire seatd xdg-user-dirs firefox swayidle wlopm`
