Trying to get a group to turn off/on even when 1 is not responsive

Configuration
1

I’m trying to make a simple button automation using a flic bluetooth button.

It works perfectly if both lights are powered. But if i manually have 1 switch turned off the automation does nothing.

Here is my group:

bed: 
  name: Bedroom
  entities:
    - light.Bedroom
    - light.Computer

And here is my automation:

automation:
  - alias: switch lights in bedroom
    trigger:
      platform: event
      event_type: flic_click
      event_data:
        button_name: flic_xxxxxxxxxxx
        click_type: single
    action:
      service_template: >
        {% if is_state('group.bed', 'off') %}
          homeassistant.turn_on
        {% else %}
          homeassistant.turn_off
        {% endif %}
      entity_id: group.bed
