How It Works

When Firehose Mode is active, the system randomly samples a portion of your drives rather than uploading everything. It queues approximately 10 segments at a time for transmission, whether sunnypilot is actively engaged or not. Both engaged and disengaged driving data contributes to simulator training.

No special driving behavior is needed. Normal driving patterns work fine.

Status Display

The panel shows whether Firehose Mode is currently active or inactive:

• Active (green): The device is connected to an unmetered network and uploading data.
• Inactive (red): Connect to an unmetered Wi-Fi network to begin uploading.

If available, the panel also displays the number of segments you have contributed to the training dataset.

Optional: Mobile Upload

Devices with hotspot access or unlimited data plans can upload data while driving, removing the need for weekly Wi-Fi sessions.
