About Telemetry Methods
Tessie uses different methods to connect to your vehicle, depending on your model.
Polling
For legacy (MCU1) Tesla Model S/X and Tesla Business vehicles
How it works: Tessie <> Tesla <> Your Tesla
Tessie regularly requests vehicle data from Tesla to collect analytics. Tesla attempts to contact the vehicle, retrieve the requested data and send it back to Tessie.
Direct Telemetry
For all other vehicles
How it works: Tessie <> Your Tesla
Tessie configures your vehicle to stream telemetry data directly to Tessie using an end-to-end encrypted channel.
