BYD EV Pro

BYD EV Pro

Car App, Companion App, optional T-Box, and Home Assistant integration for BYD DiLink vehicles

BYD EV Pro is an ecosystem made of separate parts. Keep them separate during setup and troubleshooting:

  • Car App: the Flutter app installed on the BYD DiLink head unit. Repository evidence identifies it as byd_ev_pro version 2.0.4+76.
  • Companion App: the phone app that pairs to the Car App and relay. Repository evidence identifies it as ev_pro_companion version 1.0.3+40.
  • T-Box: optional firmware/hardware for telemetry publishing, Cloud command handling, BLE proximity behavior, GPS, diagnostics, and firmware update flows. Public packaging and physical installation requirements still need product confirmation.
  • Home Assistant integration: a custom integration that receives Car App webhook pushes.
