Thank you VERY much !

I think that

  am220ac_refresh:
    mode: single
    sequence:
      - service: mqtt.publish
        data:
          topic: "Automower/AM_220AC/Cmd/Action"
          payload: "Refresh"

should be

  am220ac_refresh:
    mode: single
    sequence:
      - service: mqtt.publish
        data:
          topic: "Automower/AM_220AC/Action"
          payload: "Refresh"

Alan's doc says:

A special topic (/Action) allows for:

• A request of all values for refresh of display (payload "Refresh")

I fixed the problem you mentioned. Additionally, I took advantage of the new MQTT capabilities (unit of measurement in number.mqtt, select.mqtt, and button.mqtt) to further simplify the setup. The updated snippet contains all these improvements.

Thank you. I'll have a look at the diff. Do you maintain this somewhere else than in a snippet ? i.e. a repository ? I think this is well done enough to be useful to all people using Alan's module and Home Assistant.

Did you get a doc/note about MQTT those topics or is this all based on reading OpenHAB settings ?

In any case, thanks a lot.

I just hosted it in a full-fledged repository at https://gitlab.com/frnchfrgg/home-assistant-automower
