Unique ID error when trying to add a switch to an area within home assistant

Configuration

Hope you all can help me with the attached error showing up in my yaml config file. I have done quite a bit of reading and I’m not sure that there is a solution. Essentially, I have “wrapped” a philips hue smart outlet to make it show up as a switch entity instead of as a light. I would now like to add that entity to an area within home assistant. I am reading that entities added/ created in the config file rather than by the UI often cannot have a unique ID? Are there any work arounds/ fixes to this issues? . Thank you all for any guidance you can give. (I am a newbie with home assistant in general). Thanks again!! Below is an attempt at the copy paste of the section of my yaml I am speaking of. (It doesn’t like my attempt at adding the unique id property in.-- I am getting an error attempting to fix the issue like that)

switch:
  - platform: template
    unique_id: projector_power_switch
    switches:
      projector_power:
        value_template: "{{ is_state('light.projector_power', 'on') }}"
        turn_on:
          service: light.turn_on
          target:
            entity_id: light.projector_power
        turn_off:
          service: light.turn_off
          target:
            entity_id: light.projector_power

You have unique_id in the wrong place. You have to specify it per switch not for the platform. Try this and it should work fine:

switch:
  - platform: template
    switches:
      projector_power:
        unique_id: projector_power_switch
        value_template: "{{ is_state('light.projector_power', 'on') }}"
        turn_on:
          service: light.turn_on
          target:
            entity_id: light.projector_power
        turn_off:
          service: light.turn_off
          target:
            entity_id: light.projector_power
