Changer l'icone d'un volet pour voir son état

Oui, mais si on regarde le code sur quel je me base,

Ma version est :
Home Assistant 2023.6.2 Supervisor 2023.09.2 Operating System 10.2 Interface utilisateur : 20230608.0 - latest

Voici ici pourquoi j’ai besoin de fonction cover.

En gros tout simplement, parce qu’avec mes boutons switch, c’est boutons sont inversés, c’est-à-dire que lorsque le volet est ouvert, le bouton a dit de fermer

switch:
  - platform: template
    switches:
      tousvolets:
        friendly_name: "Tous les volets"
        value_template: "{{ is_state('switch.volet_hangar_md', 'on') }}"
        turn_on:
          - service: switch.turn_on
            target:
