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:

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:

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.
