Tesla CAN bus logging/display with Raspberry Pi

I posted a video about my project in which I use a Raspberry Pi to display realtime CAN bus data in the car's own web browser.


Let me know if you have any questions. -Ben

I show how to collect detailed CAN bus data from a Tesla Model S, and display it in the car's own web browser!

I used socket.io, which is a module that installs into node.js: socket.io

Basic sequence to setup the server on the Pi:
sudo ip link set can0 type can bitrate 500000 listen-only on
sudo ip link set can0 up

candump -cae can0,0:0,#FFFFFFFF

candump -cae can0,0:0,#FFFFFFFF | grep 106 | awk -Winteractive '{ print $10}' | node app.js

I will post the node.js code on my blog:

Very nice work. Thank you for posting this! I have been searching for a decent Linux CAN setup for doing analysis on my Model S. This will certainly improve over the current Android setup I have and looks like I may be able to feed in some old captures I have for better analysis.

Looking forward to the ultimate graphing/performance monitor you are working on!

Wonder what the best solution is to keep the Raspberry Pi firewalled from the internet connection? Maybe acting as a bridge or some other clever routing manipulation can accomplish this.
