Assistance creating a sensor

Hi.

This works fine in the template editor:

{% if states('sensor.apollo_mtr_1_cca750_presence_target_count') | int > 0 %}
  Detected
{% elif is_state('binary_sensor.apollo_msr_2_c7bfe8_radar_zone_1_occupancy', 'on') %}
  Detected
{% elif is_state('binary_sensor.apollo_msr_2_c7bfe8_radar_zone_2_occupancy', 'on') %}
  Detected
{% elif is_state('binary_sensor.apollo_msr_2_c7bfe8_radar_zone_3_occupancy', 'on') %}
  Detected
{% else %}
  Not Detected
{% endif %}

But when I try to create a binary_sensory from it in configuration.yaml, I get "'binary_sensor' is undefined":

template:
  - binary_sensor:
    - name: "Lounge Presence"
      state: >-
        {% if states('sensor.apollo_mtr_1_cca750_presence_target_count') | int > 0 %}
          Detected
        {% elif is_state('binary_sensor.apollo_msr_2_c7bfe8_radar_zone_1_occupancy', 'on') %}
          Detected
        {% elif is_state('binary_sensor.apollo_msr_2_c7bfe8_radar_zone_2_occupancy', 'on') %}
          Detected
        {% elif is_state('binary_sensor.apollo_msr_2_c7bfe8_radar_zone_3_occupancy', 'on') %}
          Detected
        {% else %}
          Not Detected
        {% endif %}
      device_class: presence

I'm probably using incorrect syntax or something. Can anyone help me with this?

I think you can make a template from the helpers page, see if that works
- Thanks for the suggsetion @Matt The Horwood.
  
  It looks like a "Combine the state of several sensors" or a "Group" helper only allow you to combine sensors of the same type.
  
  I created a binary sensor from a template using the helper, but it also returns "'binary_sensor' is undefined" when I try to access its value in the template editor with {{ states(binary_sensor.lounge_presence) }}
Try it without "template:" like

binary_sensor:

name: "Lounge Presence" [...]
- Thanks for the suggestion, @NeoNachtwaechter.
  
  But doing that makes configuration.yaml invalid:
  
  Give us the plain English of what you think this is supposed to do first 😉
  
  Your error suggests a yaml formatting issue.

I found the solution. configuration.yaml needed to have the following syntax, with the defined values being true or false (instead of "Detected" or "Not Detected"):

template:
  - binary_sensor:
      - name: "Lounge Presence"
        state: >-
          {% if states('sensor.apollo_mtr_1_cca750_presence_target_count') | int > 0 %}
            true
          {% elif is_state('binary_sensor.apollo_msr_2_c7bfe8_radar_zone_1_occupancy', 'on') %}
            true
          {% elif is_state('binary_sensor.apollo_msr_2_c7bfe8_radar_zone_2_occupancy', 'on') %}
            true
          {% elif is_state('binary_sensor.apollo_msr_2_c7bfe8_radar_zone_3_occupancy', 'on') %}
            true
          {% else %}
            false
          {% endif %}
        device_class: presence
