Telemetry On Legacy Vehicles

Vehicle firmware version 2025.20 adds Fleet Telemetry support for Model S and Model X vehicles with Intel Atom car computers.

These vehicles do not require a Virtual Key; instead, a user with access to the vehicle must enable "Allow Third-Party App Data Streaming" in the Safety screen of the vehicle.

Once you have enabled Allow Third-Party App Data Streaming you can simply Subscribe to Telemetry in Settings->Tesla Account on TeslaFi.  Fleet keys are not required and you can simply select the Subscribe button.

If you are still seeing that Allow Third-Pary App Data is not enabled on TeslaFi please try restarting your vehicle and check again.

After subscribing to Telemetry it can take some time for data to start streaming.  If you are not seeing data within 15 minutes a restart of the car may help as well.
