Log and Analyse Wifi or Bluetooth OBD2 Data with Python and Javascript.

A dashboard for monitoring vehicle information to identify problems, calculate consumption, view/clear fault codes, etc

---

How to use

You need a obd2 adapter like ELM-327, I used a Wifi one.

You need Docker or install the python requirements in your env or venv

Docker Install:

• Install docker if not already installed: Docker Install

Run Docker:

• Run: docker compose up

Local run:

• cd app
• FLASK_ENV=development flask run

Open http://localhost:5000 in your browser

How it works

• Using flask as frontend and api
• Using python-obd to comunicate with adapter
• Connects a wifi device in default '192.168.0.10:35000' address
• If bluetooth, configure properly, see Python-OBD Docs

How to code

• HTML, CSS and JavaScript files are in app/templates

• Static files in app/static

• Flask routes in app/app.py

• OBD2 Connection in app/connection.py

• You can run in background to keep terminal free with docker-compose up -d
  See logs with docker-compose logs. And to keep showing: docker-compose logs -f

• Stop and Remove all Containers about: docker-compose down

What's next

• Create dashboard for different views
• Calculate differential ratio from velocity to estimate actual gear
• Change docker to bind bluetooth device
• Use Web Sockets / ASync
• Record log in time-series format
