Welcome to chffrplus

chffrplus is an open source dashcam.

This is the shipping reference software for the comma EON Dashcam DevKit. It keeps many of the niceities of openpilot, like high quality sensors, great camera, and good autostart and stop. Though unlike openpilot, it cannot control your car. chffrplus can interface with your car through a panda, but just like our dashcam app chffr, it is read only.

It integrates with the rest of the comma ecosystem, so you can view your drives on the chffr app for Android or iOS, and reverse engineer your car with cabana.


Right now chffrplus supports the EON Dashcam DevKit for hardware to run on.

Install chffrplus on a EON device by entering during NEOS setup.
