Count amount of lights on

Configuration
1

Hey, so i’ve got these group with id light.luces witch has four light in it, and i want to display on my dashboard the amount of light of that group that are currently on.
Is there a way to do it from the UI?

This is how I did it:


template:
  - sensor:
      - name: number_of_lights_on
        unique_id: sensor_number_of_lights_on
        icon: mdi:lightbulb-group
        unit_of_measurement: "on"
        state: >
          {% set   lights = [
           'light.luces'
           ] %}
           {{ expand(lights) | selectattr('state','eq','on') | list | count }}

Then just use sensor.number_of_lights_on to show the total on the UI.

I am very similar, but I use a reject group to exclude light groups.

template:
  - name: "count of lights on"
    icon: mdi:lightbulb-on
    unique_id: count_lights_on
    unit_of_measurement: "on"
    state: >
      {% set reject = [
        'light.house_lights',
        'light.lux_scenes',
        'light.downstairs_lights',
        'light.upstairs_lights',
        'light.livingroom_lamps',
        'light.livingroom_lamps_half_on',
        'light.livingroom_lamps_half_off',
        'light.livingroom_blooms',
        'light.hallway',
        'light.outside',
        'light.landing',
        'light.patio'
        ]
      %}
      {{ states.light
        | rejectattr('entity_id', 'in', reject)
        | selectattr('state','equalto','on')
        | list
        | length
      }}
