Automation triggered on zone entry/leave assistance

Configuration
1

Im attempting to make an automation that’s notifies the alert group when users enter or leave a certain zone. Im having issues with multiple trigger alerts though due to gps jumping around. How would I go about adding code to my current yaml below to put like a 30 second delay on the trigger.

alias: Alert - Arrival & departure ECC
description: ''
trigger:
  - platform: zone
    entity_id:
      - person.name1
      - person.name2
    zone: zone.ECC
    event: enter
  - platform: zone
    entity_id:
      - person.name1
      - person.name2
    zone: zone.ECC
    event: leave
condition: []
action:
  - service: notify.all_devices
    data:
      message: |
        {% if trigger.event == "leave" %}
          {{ trigger.from_state.attributes.friendly_name }} has left {{ trigger.zone.attributes.friendly_name }}
        {% else %}
          {{ trigger.from_state.attributes.friendly_name }} Arrived at the {{ trigger.zone.attributes.friendly_name }}
        {% endif %}
mode: single

I’d do it with the state of the person, not the zone.

If you use the trigger with each person, you can easily use the for attribute (not sure how to call it, technically it’s not an attribute).

alias: Alert - Arrival & departure ECC
description: ''
trigger:
  - platform: state
    entity_id:
      - person.name1
      - person.name2
    to:
    for: '00:00:30'
condition: []
[...]

You could then use the trigger variable to set the according message.

Don’t forget you can set the accuracy requirements to prevent inaccurate GPS data from screwing things up.

How would I go about this?

Check the gps_accuracy of the person.
