            friendly_name: 'Lights of count'
            unique_id: lights_of_count
            value_template: > 
              {%- set search_state = 'on' %}
              {%- set search_areas = ['Master Bedroom','Living Room','Kitchen','Kids Room','Bathroom','Dining Room','Garage'] %}
              {%- set ns = namespace(lights=[]) %}
              {%- for light in states.light 
  selectattr('state','eq', search_state)
          | rejectattr('object_id', 'search', 'segment')%}
            {%- for area in search_areas %}
              {% if area_name(light.entity_id) == area %}
                {%- set ns.lights = ns.lights + [ light.entity_id ] %}
              {% endif%}
              {%- endfor %}
              {%- endfor %}
              {{ ns.lights| list | length }}

Hey friend I think this is the header card, So whats exactly not working, like you get error messages or unknown/unavailable states from the sensor. Could you give me more context on what you have done?

Make sure you pay attention to the steps and restart Home assistant after creating the sensor, the lights group and adding the lights to the Area's you've created.

yes it was the header card I have trouble with the yaml when I pasted the code im getting this error in the bottom of the last line

can not read a block mapping entry; a multiline key may not be an implicit key YAML
