Suggested new configuration to group by room instead of entity

  exposed_domains:
    - switch
    - light
    - group
  room_config:
    - name: 'Living Room'
      expose: true
      entities:
         - light.living_room
         - switch.living_room
    - name: 'Kitchen'
      expose: true
      entities:
        switch.kitchen:
          name: CUSTOM_NAME_FOR_GOOGLE_ASSISTANT
          aliases:
            - BRIGHT_LIGHTS
            - ENTRY_LIGHTS
