To use physical Modbus hat/adapter in EVCC on the same raspberry pi used by home assistant, the config.txt in the boot partition of home assistant should be edited for the device to be available. This instruction adds that information to the docs

Please spell check, German is not my first language and mostly used translator tools and common sense.

Dafür musst du externe Geräte für das evcc-Addon aktivieren.

Thanks for the suggestion

This suggestion implies that the change only makes external devices available for evcc, but actually it's for whole home assistant and its addons, i think it's fair to clarify this, when someone tries to debug/troubleshoot an issue.

Dafür musst du externe Geräte für Home Assistant aktivieren, was auch das evcc-Addon einschließt. Kommentiere dafür die Zeile uart = 1 in der config.txt auf der Home Assistant OS Boot-Partition ein.

What do you think about this? and is it grammatically correct?

@WesSec thanks for your PR 🙌

The German translation was in deed a little clunky, I've made suggestions. Can you update the English translation as well?
