The library allows you to listen to various telemetry signals from Tesla vehicles, and provides a convenient way to handle these signals using typed listen methods. ## Capabilities - Connect to the Teslemetry Stream service - Listen to various telemetry signals from Tesla vehicles - Handle signals using typed listen methods - Write custom listeners for multiple signals ## Installation `pip install teslemetry-stream` ## Usage The TeslemetryStream class requires: - session: an aiohttp.ClientSession - access_token: an access token from the [Teslemetry console](https://teslemetry.com/console) - vin: If you only want to use a single vehicle, otherwise use `create_vehicle` - server: Override the Teslemetry server to connect to: - api.teslemetry.com (recommended and default) - na.teslemetry.com - eu.teslemetry.com The full list of possible values are provided in `TelemetryFields` and `TelemetryAlerts` To connect, either use `async with` on the instance, call `connect()`, or register an callback with `async_add_listener`, which will connect when added and disconnect when removed. Using `connect()` or `listen()` will require you to close the session manually using `close()`. ## Example The following example puts the listening loop in the background, then stopping after 20 seconds. ``` async def main(): async with aiohttp.ClientSession() as session: async with TeslemetryStream( access_token="", vin="", # for single vehicles server="na.teslemetry.com" # or "eu.teslemetry.com" session=session, ) as stream: def callback(event): print(event["data"]) remove = stream.async_add_listener(callback) print("Running") await asyncio.sleep(60) remove() ``` ## Using Typed Listen Methods The library provides typed listen methods for various telemetry signals. These methods allow you to listen to specific signals and handle their data in a type-safe manner. Here is an example of using the typed listen methods: ```python async def main(): async with aiohttp.ClientSession() as session: async with TeslemetryStream( access_token="", vin="", # for single vehicles session=session, ) as stream: vehicle = stream.get_vehicle("") def battery_level_callback(battery_level): print(f"Battery Level: {battery_level}") def vehicle_speed_callback(vehicle_speed): print(f"Vehicle Speed: {vehicle_speed}") remove_battery_level_listener = vehicle.listen_BatteryLevel(battery_level_callback) remove_vehicle_speed_listener = vehicle.listen_VehicleSpeed(vehicle_speed_callback) print("Running") await asyncio.sleep(60) remove_battery_level_listener() remove_vehicle_speed_listener() ``` ## Writing Your Own Listener with Multiple Signals You can also write your own listener that listens to multiple signals. Here is an example of writing a custom listener: ```python async def main(): async with aiohttp.ClientSession() as session: stream = TeslemetryStream( access_token="", vin="", # for single vehicles server="na.teslemetry.com" # or "eu.teslemetry.com" session=session, ) await stream.connect() vehicle = stream.get_vehicle("") def custom_listener(event): if "BatteryLevel" in event["data"]: print(f"Battery Level: {event['data']['BatteryLevel']}") if "VehicleSpeed" in event["data"]: print(f"Vehicle Speed: {event['data']['VehicleSpeed']}") remove_custom_listener = stream.async_add_listener(custom_listener, {"vin": "", "data": {"BatteryLevel": None, "VehicleSpeed": None}}) print("Running") await asyncio.sleep(60) remove_custom_listener() await stream.close() ``` ## Public Methods in TeslemetryStream Class ### `__init__(session: aiohttp.ClientSession, access_token: str, server: str | None = None, vin: str | None = None, parse_timestamp: bool = False)` Initialize the TeslemetryStream client. ### `get_vehicle(vin: str) -> TeslemetryStreamVehicle` Create a vehicle object to manage config and create listeners. ### `connected -> bool` Return if connected. ### `get_config(vin: str | None = None) -> None` Get the current stream config. ### `find_server(self) -> None` Find the server using metadata. ### `update_fields(fields: dict, vin: str) -> dict` Modify the Fleet Telemetry configuration. ### `replace_fields(fields: dict, vin: str) -> dict` Replace the Fleet Telemetry configuration. ### `config(self) -> dict` Return current configuration. ### `connect(self) -> None` Connect to the telemetry stream. ### `close(self) -> None` Close connection. ### `async_add_listener(callback: Callable, filters: dict | None = None) -> Callable[[], None]` Add listener for data updates. ### `listen(self)` Listen to the telemetry stream. ### `listen_Credits(callback: Callable[[dict[str, str | int]], None]) -> Callable[[], None]` Add listener for credit events. ### `listen_Balance(callback: Callable[[int], None]) -> Callable[[], None]` Add listener for credit balance. ## Public Methods in TeslemetryStreamVehicle Class ### `__init__(stream: TeslemetryStream, vin: str)` Initialize the TeslemetryStreamVehicle instance. ### `get_config(self) -> None` Get the current vehicle config. ### `update_fields(fields: dict) -> dict` Update Fleet Telemetry configuration for the vehicle. ### `replace_fields(fields: dict) -> dict` Replace Fleet Telemetry configuration for the vehicle. ### `config(self) -> dict` Return current configuration for the vehicle. ### `listen_State(callback: Callable[[bool], None]) -> Callable[[],None]` Listen for vehicle online state polling. The callback receives a boolean value representing whether the vehicle is online. ### `listen_VehicleData(callback: Callable[[dict], None]) -> Callable[[],None]` Listen for vehicle data polling events. The callback receives a dictionary containing the complete vehicle data. ### `listen_Cellular(callback: Callable[[bool], None]) -> Callable[[],None]` Listen for cellular connectivity events. The callback receives a boolean value indicating whether the cellular connection is established. ### `listen_Wifi(callback: Callable[[bool], None]) -> Callable[[],None]` Listen for WiFi connectivity events. The callback receives a boolean value indicating whether the WiFi connection is established. ### `listen_Alerts(callback: Callable[[list[dict]], None]) -> Callable[[],None]` Listen for vehicle alert events. The callback receives a list of dictionaries containing alert information. ### `listen_Errors(callback: Callable[[list[dict]], None]) -> Callable[[],None]` Listen for vehicle error events. The callback receives a list of dictionaries containing error information. ### `listen_*` Methods The `TeslemetryStreamVehicle` class contains a `listen_*` methods for each telemetry signal. These methods allow you to listen to specific signals and handle their data in a type-safe manner.
