[Feature]: Inverted slider for cover card

Is your feature request related to a problem?

I want to use the mushroom cover cards to control my KNX shutters in my house. In generell everything works. The problem is, that for the position slider, i need an inverted value, because in KNX 0% is fully open and for Home Assistant is 100% fully opened. Before i used the mushroom cover cards, i build the cards myself and for the slider is used a seperate entity with the following code:

cover:
  platform: template
  covers:
    cover_og_buero_inverted: ##Büro
      friendly_name: Buero Rolladen inverted
      position_template: >
        {{100 - (state_attr(‘cover.og_buero_rolladen’,‘current_position’)|int)}}
      set_cover_position:
        service: cover.set_cover_position
          data_template:
            entity_id: cover.og_buero_rolladen
            position: >
              {{100 - position}}

But in the mushroom cover card its not possible to use an seperate entity only for the slider. Up/down/hold works perfectly with the buttons.

Can you format your code using this https://docs.github.com/en/get-started/writing-on-github/working-with-advanced-formatting/creating-and-highlighting-code-blocks ? Indentation is very important in yaml 😅

That shouldn’t be required for KNX. The integration does the translation of the percentage. A closed cover shows 100% in KNX and 0% in Home Assistant. That’s the default and I can confirm this in my installation. Are you sure you don’t mix up anything?

Home Assistant definition:

knx:
  cover:
    - name: buro_jalousie_fenster
      move_long_address: 3/1/81
      move_short_address: 3/2/81
      position_address: 3/3/81
      angle_address: 3/4/81
      position_state_address: 3/6/81
      angle_state_address: 3/7/81
      travelling_time_down: 44
      travelling_time_up: 45

Home Assistant Status for closed (current_position: 0): KNX Status for closed (100%):

So this shouldn’t be the case if setup by default.

I had a similar problem, but only because an exception for the vertical blinds (german: "Markise). For me it’s natural that the button down would “open” it and the button up would close it (similar to the physical orientation). So the Buttons worked as expected. But the status felt wrong for me, because Open is for me when it’s out (create shade). and closed when it’s rolled up (no shade).

So i created my own card with inverted state in the GUI. It was not out of the box, but works well now for me. You need card-mod and stack-in-card. With them I created basically a template card, which shows the inverted icon and state. And below the default mushroom cover card with the buttons.

type: custom:stack-in-card
cards:
  - type: custom:mushroom-template-card
    card_mod:
      style: |
        ha-card {
          padding-bottom: 0 !important;
        }
    primary: Markise
    secondary: |-
      {% set pos = state_attr(entity, 'current_position') %}
      {{
        'Geschlossen' if pos == 100 else
        'Schliesst' if states(entity) == 'opening' else
        'Öffnet' if states(entity) == 'closing' else
        'Offen'
      }}{{ (' - ' +  (100-pos) | string + '%') if pos > 0 and pos < 100 }}
    icon: |-
      {{
        'mdi:blinds-open' if state_attr(entity, 'current_position') == 100 else
        'mdi:arrow-down-box' if states(entity) == 'closing' else
        'mdi:arrow-up-box' if states(entity) == 'opening' else
        'mdi:blinds'
      }}
