Self-host a Tesla Fleet Telemetry server and push a fleet_telemetry_config so vehicles stream data over WebSocket instead of being polled

Steps
Deploy the open-source teslamotors/fleet-telemetry server on infrastructure with a public internet-facing endpoint and a valid TLS certificate
Register the server's connection details (host, port) as the telemetry target in your Fleet API developer application
Send a fleet_telemetry_config request to the vehicle_data endpoint specifying which signals to stream and the minimum interval for each
Confirm the vehicle establishes a persistent WebSocket connection to your server and starts pushing records that changed since the configured interval
Monitor the server's connectivity event stream to track vehicle online/offline state as a proxy for reachability instead of polling vehicle_data
Handle ack/error/rate-limit responses from the telemetry server and re-issue configuration if a vehicle falls back to disconnected
Known gotchas
This is not Tesla pushing data to your API over SSE from Tesla's servers — your own server must be publicly reachable and vehicles connect outward to it, so firewall/NAT setup is on you
A vehicle can be configured to stream to a maximum of five third-party telemetry servers at once; exceeding that requires the owner to remove another app's configuration first
Signals are sent on-change but rate-limited by the configured minimum interval, so setting an interval of 0 does not guarantee continuous streaming and can trigger throttling
