Custom state names for template switch (Open/Closed instead of On/Off)

Configuration
1

I have a template switch to combine an actor and a door sensor, and I’d like to show “Open” or “Closed” instead of “On” and “Off”. Is this possible within the template? I cannot do it via frontend because I use the entity in Android Auto.

Here’s the current code:

switch:
  - platform: template
    switches:
      garagentor:
        friendly_name: "Garagentor"
        value_template: "{{ is_state('binary_sensor.offnungskontakt_garagentor_offnung', 'on') }}"
        turn_on:
          action: switch.toggle
          target:
            entity_id: switch.fingerbot_garagentor_schalter
        turn_off:
          action: switch.toggle
          target:
            entity_id: switch.fingerbot_garagentor_schalter
        icon_template: >-
          {% if is_state('binary_sensor.offnungskontakt_garagentor_offnung', 'on') %}
            mdi:garage-open
          {% else %}
            mdi:garage
          {% endif %}
