This project is to detect which cars are in my garage as well as if the garbage bins are present. I use a simple object detection model along with an IP Camera in my garage. I publish the state as bianry sensors for use in HomeAssistant. The images used for training are here: https://app.roboflow.com/egge-public/garage/overview

The script uses a rolling average to determine if the object is present or absent, and also skips updating if it detects a person, as they may be obscuring something. I also trained it to recongize my toolbucket. This is a sort of sanity / calibration check. If it finds nothing in the scene, it's likely a system problem, so it shouldn't update the state of the objects.

You need to create a config file, example:

[file]
path=/mnt/capture

[camera]
user=admin
password=*****
host=garage-cam.home

[mqtt]
host=mqtt
port=1883

In HomeAssistant I have a dashboard showing my garage (along with a camera view)

Here is one of my automations, which closes my garage door after I leave:

alias: Garage Close Civic departs
description: "Close left garage door after departure "
trigger:
  - platform: state
    entity_id:
      - person.brian
    to: not_home
    from: home
condition:
  - condition: state
    entity_id: binary_sensor.honda_civic
    state: "off"
  - condition: state
    entity_id: cover.garage_door_left
    state: open
action:
  - service: cover.close_cover
    target:
      entity_id:
        - cover.garage_door_left
    data: {}
  - wait_for_trigger:
      - platform: state
        entity_id:
          - cover.garage_door_left
        to: closed
    timeout: "60"
  - service: notify.mobile_app_brians_iphone_x
    data:
      message: Garage door left is {{ states('cover.garage_door_left') }}
      data:
        entity_id: camera.garage_cam
        url: /lovelace-mobile/garage/
mode: single

The arriving home automations are a bit more complicated, because I might be driving either car. If both cars are away, I'm driving the Civic. If the Civic is present, I'm driving the CRV.
