S3XY-candump

Python tools to dump CAN bus data from a Tesla vehicle using Enhauto S3XY buttons / The Commander

S3XY Commander can connect to two different CAN buses on a Tesla vehicle. With Wi-Fi enabled, it can forward the raw can data over Wi-Fi using the Panda protocol.

This project has only been tested on Model 3 2022. You should change the DBC file used if you are using a different vehicle. The DBC file is only used as a list of can message IDs to subscribe to.

Candash project was great help for understanding the Panda protocol.

Instructions

1. Connect the S3XY Commander

2. Enable Wi-Fi in Commander settings in S3XY app

   Now you may test the Wi-Fi Panda data using ScanMyTesla app. But make sure to disconnect after testing - only one device can be connected to Wi-Fi at a time

3. Connect your device (for example Raspberry Pi or a laptop) to the Commander's Wi-Fi

4. Check the hardcoded settings in s3xy-candump.py

5. Run the project: python3 s3xy-candump.py

Output formats

Currently two output formats are supported and enabled by default, and they should cover importing the data to variety of tools:

• candump - Should match with log exports of candump tool of can-utils
• savvycan - Should match with SavvyCAN / GVRET format.

SavvyCAN format can be used with make_cabana_route to import the dump into Openpilot Cabana
