Notification from proximity entity

Configuration
1

Hi,
I have an automation that takes data from the proximity sensor and I would like to associate its distance to the notification of the single entity. I can’t find the trigger to insert in the notification. I tried with {{ states(‘trigger.to_entity_id’) }} but it didn’t work.

I report the complete automation:

alias: notify distance
description: ""
triggers:
  - trigger: numeric_state
    entity_id:
      - sensor.casa_composite_aaa_distanza
      - sensor.casa_composite_bbb_distanza
      - sensor.casa_composite_ccc_distanza
    for:
      hours: 0
      minutes: 0
      seconds: 15
    above: 950
  - trigger: numeric_state
    entity_id:
      - sensor.casa_composite_aaa_distanza
      - sensor.casa_composite_bbb_distanza
      - sensor.casa_composite_ccc_distanza
    for:
      hours: 0
      minutes: 0
      seconds: 15
    below: 950
conditions: []
actions:
  - data:
      message: |
        Ore {{ states('sensor.time') }} di {{ states('sensor.weekday') }} {{
        states('sensor.data_ita_custom') }}    
      title: |
        {% if trigger.event == "above" %}
          {{ trigger.to_state.name }} dista {{ ?????? }} da casa
        {% else %}
          {{ trigger.to_state.name }} sta rientrando a casa e dista {{ ??????? }}
        {% endif %}    
    action: notify.miotg

Thanks in advance
