I am using frigate to monitor my cameras. When a car is found at the gate by frigate (drive cam), I send the image to platerocognizer and then process the image to open the gate. If someone is leaving the (gate cam) opens the gate to let them out.

alias: A car is at the gate
description: >-
  If a car has been seen by the drive camera send the image to platerocogniser. 
  If it was the gate camera then someone is leaving, open the gate
triggers:
  - topic: frigate/events
    value_template: "{{ value_json.type }}"
    trigger: mqtt
conditions:
  - condition: template
    alias: A vehicle has been spotted
    value_template: "{{ trigger.payload_json['after']['label'] == 'car' }}"
actions:
  - if:
      - condition: template
        alias: A car is leaving
        value_template: "{{ trigger.payload_json['after']['camera'] == 'gate' }}"
      - alias: The gate is closed
        type: is_not_open
