Just a note to say that I will look forward to using your component, at the moment I integrate my Keba P30 through some awkward Node-Red scripting !

Nice to hear this!

You could test my implementation by copying the content of the "keba" folder from "homeassistant/component/keba" (e.g. from my forked repo) to "[your Home Assistant config folder]/custom_components/keba". Then you need to add at least the following lines to your config file:

keba:
  host: 192.168.178.2
  rfid: XXXXXXXX

The integration automatically creates all relevant sensors and switches. that can be easily found with the prefix "keba_".

If you provide me with feedback or ideas for improvement, I can work on it. It might also speed up the PR acceptance, if another user successfully tested the code.

Update: The integration is running stable in my environment (BMW Wallbox) and was successfully tested on a KEBA P30x by Erik73 in the forum.

Can be merged when last comment is addressed and build passes.

@dannerph do you intend to add support for broadcasted messages? According to the UDP Programming Manual, that would allows us to update sensors immediately instead of requesting the data at the polling interval.
