Automation using proximity integration

Configuration
1

I setup this integration:

proximity:
  casa:
    zone: home
    devices:
      - device_tracker.sm_s908b
      - device_tracker.life360_fha
    tolerance: 200
    unit_of_measurement: m

And then i created this automation to announce when and which of the two device_trackers is near zone Home. Actually it works but it announce always only one of the device. I would like to understand how to distinguish which of the two device_trackers is closest to the zone inserted in the automation.

- id:A 500 metri da casa
  alias: A 500 metri da casa
  mode: single
  trigger:
  - platform: numeric_state
    entity_id:
    - proximity.casa
    below: 500
  condition:
    condition: template
    value_template: '{{ trigger.to_state.attributes.dir_of_travel  == "towards" }}'
  action:
  - service: notify.alexa_media
    data_template:
      target:
      - media_player.echo_plus
      data:
        type: tts
      message: '{{trigger.to_state.object_id[:-5] | capitalize}} è a 500 metri da
        casa e sta tornando!'

Maybe using some variables?
Can someone help me in this?

Use the nearest attribute that is created by the proximity sensor:

action:
  - service: notify.alexa_media
    data_template:
      target:
      - media_player.echo_plus
      data:
        type: tts
      message: '{{trigger.to_state.attributes.nearest }} è a 500 metri da
        casa e sta tornando!'
