Feature Request: ignore entities time based

[moehringn]

It would be awesome to also have the option to ignore entities time based.
E.g. I have ahoyDTU which gives me solar panel channels over MQTT. But 4 entities from that MQTT integration will be unavailable at night because there's obviously nothing to receive.
It would be great to be able to have some sensor/integration about sunrise and sunset (probably some weather forecast integration will do that) and based on that, a certain list of entities is then ignored between a certain time frame.
Would something dynamic like this be even possible?

Also highly intereseted on that ability

Try this out and see if it does what you want.
You must have the Sun integration installed.
You must also create the group group.night_ignored_unavailable_entities.

template:
  - sensor:
      - name: "Unavailable Entities"
        unique_id: unavailable_entities
        icon: "{{ iif(states(this.entity_id)|int(-1) > 0,'mdi:alert-circle','mdi:check-circle') }}"
        state_class: measurement
        unit_of_measurement: entities
        state: >
          {% set entities = state_attr(this.entity_id,'entity_id') %}
          {{ entities|count if entities != none else none }}
        attributes:
          entity_id: >
            {% set ignore_seconds = 60 %}
            {% set ignore_ts = (now().timestamp() - ignore_seconds)|as_datetime %}
            {% set is_night = states('sun.sun') == 'below_horizon' %}
            {% set ignored = state_attr('group.ignored_unavailable_entities','entity_id') %}
            {% set ignore_night = state_attr('group.night_ignored_unavailable_entities','entity_id') %}
            {% set entities = states|rejectattr('domain','eq','group')
                |rejectattr('last_changed','ge',ignore_ts) %}
            {% set entities = entities|rejectattr('entity_id','in',ignored)
                if ignored != none else entities %}
            {% set entities =  entities|rejectattr('entity_id','in',ignore_night)
                if is_night and ignore_night != none else entities %}
            {{ entities|map(attribute='entity_id')|reject('has_value')|list|sort }}

group:
  ignored_unavailable_entities:
    entities:
      - sensor.my_ignored_sensor

  night_ignored_unavailable_entities:
    entities:
      - sensor.skin_type_1_safe_exposure_time
      - sensor.skin_type_2_safe_exposure_time
      - sensor.skin_type_3_safe_exposure_time
      - sensor.skin_type_4_safe_exposure_time
      - sensor.skin_type_5_safe_exposure_time
      - sensor.skin_type_6_safe_exposure_time

@jazzyisj thank you very much. I have tested your modification with some entities the last days and it works perfect. Thank you very much.
