How to list all sensors with state = 'unavailable', 'none' or 'unknown'

Thanks for this post! I found it very helpful.

For anyone interested, here is how it is implemented in my setup. It’s pretty much the same, but I filtered out more types of things in my query out of necessity.

- trigger:
    - platform: time_pattern
      minutes: "*"
  sensor:
    - name: Unavailable Entities
      icon: mdi:help-circle-outline
      state: "{{ states | selectattr('state', 'in', ['unavailable', 'unknown', 'none']) | rejectattr('domain', '==', 'button')  | rejectattr('entity_id', 'search', '_device_temperature$') | rejectattr('domain', 'in', ['device_tracker', 'person']) | rejectattr('entity_id', 'search', '_charger_type$') | map(attribute='entity_id') | reject('==', 'sensor.unavailable_entities') | list | length }}"
      unit_of_measurement: entities
      state_class: measurement
      attributes:
        unavailable:            "{{ states | selectattr('state', 'in', ['unavailable']) | rejectattr('domain', '==', 'button')  | rejectattr('entity_id', 'search', '_device_temperature$') | rejectattr('domain', 'in', ['device_tracker', 'person']) | rejectattr('entity_id', 'search', '_charger_type$') | map(attribute='entity_id') | reject('==', 'sensor.unavailable_entities') | list }}"
        unknown:                    "{{ states | selectattr('state', 'in', ['unknown']) | rejectattr('domain', '==', 'button')  | rejectattr('entity_id', 'search', '_device_temperature$') | rejectattr('domain', 'in', ['device_tracker', 'person']) | rejectattr('entity_id', 'search', '_charger_type$') | map(attribute='entity_id') | reject('==', 'sensor.unavailable_entities') | list }}"
        none:                          "{{ states | selectattr('state', 'in', ['none']) | rejectattr('domain', '==', 'button')  | rejectattr('entity_id', 'search', '_device_temperature$') | rejectattr('domain', 'in', ['device_tracker', 'person']) | rejectattr('entity_id', 'search', '_charger_type$') | map(attribute='entity_id') | reject('==', 'sensor.unavailable_entities') | list }}"

@Blues what is you Frontend output? Only the counter?
