Streaming is the future of all Tesla vehicle data. The 2.9.x releases will prepare the integration for a major 3.x release that will almost entirely removes vehicle polling in 2025.
This version specifically will automatically enable streaming fields on your vehicle if you enable an entity that needs it. This means you no longer need to use the Teslemetry console to use enable or configure streaming, and ensures your vehicle is sending everything required for what you have enabled.
It also increases the polling interval to 30 minutes, because all vehicle_data responses are sent via streaming. This coordinator may be removed entirely in the future.
