## Description

S3XY CAN Hunt helps you investigate and identify unknown CAN bus signals on your Tesla. The core idea is simple: take a snapshot of the current CAN bus state, perform an action in your car, then compare what changed to pinpoint which signals are tied to that action.<br><br>How it works:<br>1. Connect to your Tesla via the S3XY OBD WiFi gateway<br>2. Take a snapshot of all current CAN bus values<br>3. Do something in the car — turn on the AC, open a window, press the brake<br>4. Compare against the snapshot to see which values changed, incremented, or toggled<br>5. Narrow down and label the signals you discover<br><br>This investigative approach lets you systematically uncover what each signal does, even without any documentation.<br><br>Features:<br>- Snapshot &amp; Compare: Freeze the CAN bus state and diff it against live data to isolate signals tied to specific actions<br>- Real-time Monitoring: Watch raw and decoded signal values update live as you interact with the car<br>- Signal Search: Filter discovered signals by CAN ID, name, or value range<br>- Data Export: Save your findings for further analysis or to share with the community<br><br>The app communicates over your local WiFi network using UDP on port 1338, working directly with raw CAN bus frames from the S3XY OBD gateway (ESP32-based OBD-II device).<br><br>Requirements:<br>- S3XY OBD WiFi gateway connected to your Tesla&#39;s OBD-II port<br>- Android device on the same WiFi network<br><br>Privacy:<br>- No data collection, tracking, or ads<br>- No internet access required beyond local network<br>- All vehicle data stays on your device
