WHY THE HECK can't we freely configure a Cover to interpret its percentage value as "percentage open" or "percentage closed"?

For me it is a nightmare, too! My cover (Velux) returns 1 (not zero) in case the cover is closed!

Then make a template cover to account for that in the meantime. And long term, write up an issue against that integration.

@sparkydave

So on a serious note, can this not be sorted out by using a template to invert the logic of the 0 and 100% ranges? I know it’s not as nice as simply having an option to choose, but perhaps as an interim solution until (if) we do get the option to invert?

You can. You just need to define it properly.

cover:
  - platform: template
    covers:
      garage_door:
        device_class: garage
        friendly_name: "Garage Door"
        value_template: "{{ state_attr('cover.xxx', 'position') | int == 100 }}"
        open_cover:
          service: cover.open_cover
          entity_id: cover.xxx
        close_cover:
          service: cover.close_cover
          entity_id: cover.xxx
        stop_cover:
          service: cover.stop_cover
        position_template: "{{ 100 - state_attr('cover.xxx', 'position') | int }}"
        set_cover_position:
          service: cover.set_cover_position
          data_template:
            entity_id: cover.xxx
            position: "{{ 100 - position }}"

All my blinds are Venetian blinds.

0% is closed
100% is closed
50% is open

Seems overly complicated???
