How to get engine and fault events posted to the family room with Car Watch

The car posts engine reads and stored fault codes into a chat room when real events happen.

Authorization notice. Car Watch is dual-use. Only use it on software, sites and systems you own or have explicit permission to test.

Who it is forA household that shares a chat room and wants to know about a car fault without someone checking the dashboard.

The problemA stored fault code or hybrid milestone is easy to miss if nobody is looking at the car.

The outcomeRoom messages with the event, the time and a plain-language explanation from the manual, posted only on real events.

What you need first

  • Raspberry Pi 5 with 16 GB RAM, as used for the measured numbers in the README
  • A microSD card with the car's owner's manual index and the local model files
  • A GroupMind room account for the car's agent, if you want room posts
  • Access to the car's own speakers and microphone for hands-free voice
  • Python 3 on the Pi, since the repo is Python with no pip dependencies

Steps

  1. Clone the repo with git clone https://github.com/ThinkOffApp/CarWatch and set up the Pi as described in the README. (inferred, check the README)
  2. Connect the car's agent to your GroupMind room, using the name you chose, such as @gle. (inferred, check the README)
  3. Drive the car and let the engine reads run, then check the room for event posts.
  4. Confirm the post names the stored code and includes the explanation from the owner's manual.

Prompt for your agent

Using the CarWatch repo at https://github.com/ThinkOffApp/CarWatch, configure the room agent for the GroupMind room <room-name>, then report the last three event posts it made. Verify that each post has a timestamp and that no post appears without a real car event.

Caveat. The README marks this use case as proven on the author's car, so other cars and OBD setups are not covered by the claim.
