Door and Window Notification Do Not Repeat

1

I have an automation set that notifies me if a door or window has been opened or closed.
One of the doors can be open/closed a few times in the space of 5 minutes.
I would like the automation to wait for at least 15 minutes before it notifies me again of an open/close.
I do have another automation that does the reverse of this one (from on to off)
How do I add this to my automation.

  trigger:
    - platform: state
      entity_id:

      from: 'off'
      to: 'on'

    - service: notify.brooks5123
      data_template:
        title: Alert

          The {{ trigger.to_state.name }} was {{ 'opened' if trigger.to_state.state == 'on' else 'closed' }}

To throttle the automation(s) to every 15 minutes you can add a condition utilizing the this variable:

condition: 
    - "{{ now() - this.attributes.last_triggered | default(as_datetime(0)) >= timedelta(minutes = 15) }}"

Keep in mind that this approach applies the throttle globally to all the trigger entities, not each individual door/window. If you wanted to do that, it would likely be easiest to do by setting up an automation(s) for each sensor.

Thanks I will give it a try.
