A Better Routeplanner supports many methods for retrieving live data from your car.
This listing shows the relative capabilities of each.
Displaying all available telemetry fields would be overwhelming, so we've simplified this down to the main functionality we offer in A Better Routeplanner:
Driving Data - State of Charge and position while driving.
Charging Data - State of Charge while charging
Calibration - Calibration to your exact car is possible with this data, because detailed car data is available.
Remote Data - You can get data while away from the car.
