Nissan LEAF OBD BLE
Plug-inRead LEAF battery data in Home Assistant
Read LEAF battery and vehicle data in Home Assistant, a home automation server, through a Bluetooth OBD-II diagnostic adapter. The integration shows charge, battery capacity, a calculated state-of-health estimate and other readings without a Nissan account.
Use a LeLink2-compatible Bluetooth Low Energy (BLE) adapter and a nearby Home Assistant Bluetooth receiver or proxy. The manual installation keeps the source notices and omits optional brand artwork. Select the correct chassis and battery profile: readings from older LEAFs are not fully verified, and saved values can stay visible while the car is off or away.
- Check the battery beyond the dashboard bars
- Control the car from your own apps
- Battery capacity and Hx readings
- Quick-charge and AC-charge counters
- Last-known readings after a server restart
