Hello, I’m using vertical stack with several glances cards to display various entities, switches and sensors on my home assistant main screen.

cards:
  - entities:
      - entity: person.he
        name: He
      - entity: person.she
        name: She
      - entity: binary_sensor.door
        name: Garage
      - entity: switch.fibaro_system_fgs223_double_relay_switch_2
        hold_action:
          action: more-info
        name: Garage
        show_icon: true
        show_name: true
        tap_action:
          action: toggle
        type: button
    show_name: true
    type: glance
  - entities:
      - entity: sensor.fibaro_system_fgbs222_smart_implant_temperature_2
        name: Extérieur
      - entity: sensor.fibaro_system_fgk101_door_opening_sensor_temperature
        name: Piscine
      - entity: sensor.fibaro_system_fgbs222_smart_implant_temperature_3
        name: Garage
    show_name: true
    type: glance
  - cards:
      - entity: switch.fibaro_system_fgs222_double_relay_switch_2x1_5kw_switch_2
        hold_action:
          action: more-info
        icon: 'mdi:arrow-up-bold-box-outline'
        name: Ouvrir les volets
        show_icon: true
        show_name: true
        tap_action:
          action: toggle
        type: button
      - entity: switch.fibaro_system_fgs222_double_relay_switch_2x1_5kw_switch
        hold_action:
          action: more-info
        icon: 'mdi:arrow-down-bold-box'
        name: Fermer les volets
        show_icon: true
        show_name: true
        tap_action:
          action: toggle
        type: button
    type: horizontal-stack
type: vertical-stack

It gives me the nice panel below :
2020-06-03 20_46_26-Aperçu - Home Assistant

But now, I would like to change the text below the top right button. It switches on and off the light in my garage, but the translation in french is not relevant. It states “Inactif” for Off and “On” for On. I would like to change the text displayed to “Eteint” while off and “Allumé” while on.
I tried to use a binary sensor instead, but then I can’t click on the icon to toggle the light. So I need to keep the switch instance, but I can’t find a way to customize it so that it says Eteint or Allumé.

Is is possible to change this state text ?

Thanks

Is it a switch controlling a light?

That’s what it looks like from the icon.

Do light entities have the correct state translations you require?

If so, convert your switch entity to a light entity using this:

Thanks, it works, and yes, the switch is a Fibaro FGS-223 connected on the garage’s lights.

It works, but now the states are shown as “Eteinte” for off (perfect), and “Actif” for on ; the on status should be “Allumée” in french for perfect correspondence.

You can assist with the correct translation:
