Add external events to Frigate Event Log via MQTT or HTTP

[tubalainen]

Describe what you are trying to accomplish and why in non technical terms
Ive got different sensors (such as PIRs etc) around my garden and would like to be able to send "external event triggers" to be logged in Frigate Events. Some of the sensors are far away from the camera but I would benefit greatly to start the "event" using an external trigger to catch even more events (mainly wild life in my case).

Describe the solution you'd like
This could be done via MQTT or via the existing HA-component/API. I would love for it to be via MQTT if possible.
It would show up just like any other triggered event with a label and the possibility to filter on the event.
The external event needs to be connected to be "per camera" to ensure that the AI doesnt double-trigger.
Ive been running Blue Iris in parallel to Frigate and have setup Blue Iris to trigger an event based on external sensors via MQTT or an HTTP trigger. Here is an example of my code for Blue Iris.

- id: cam1_3_9_person_detected_send_bi
  alias: "Frigate Cam 1 3 9 Framsidan send to BI"
  initial_state: 'on'
  trigger:
  - entity_id:
      - binary_sensor.cam1_framsidan_all_occupancy
      - binary_sensor.cam3_framsidan_all_occupancy
      - binary_sensor.cam9_uppfart_all_occupancy
      - binary_sensor.cam6_lekstugan_all_occupancy
      - binary_sensor.shelly_19_switch
      - binary_sensor.postinkast
      - binary_sensor.posttomning
      - binary_sensor.motion_sensor_ytterdorr_groventren_occupancy
    platform: state
    to: 'on'
  condition: []
  action:
    - service: shell_command.alert_bi
      data:
        url: 'https://ip:81/admin?trigger&camera=cam9_hd&user=user&pw=pass'
    - service: shell_command.alert_bi
      data:
        url: 'https://ip:81/admin?trigger&camera=cam3_hd&user=user&pw=pass'
    - service: shell_command.alert_bi
      data:
        url: 'https://ip:81/admin?trigger&camera=cam1_hd&user=user&pw=pass'
    - service: shell_command.alert_bi
      data:
        url: 'https://ip:81/admin?trigger&camera=cam8_hd&user=user&pw=pass'
    - service: shell_command.alert_bi
      data:
        url: 'https://ip:81/admin?trigger&camera=cam6_hd&user=user&pw=pass'

MAH! Just got caught by my own absence from the Frigate community. Thanks :)
