+## Data updates
+
+The **Bang & Olufsen** integration uses the [Mozart API](https://bang-olufsen.github.io/mozart-open-api), which is a local REST API with a WebSocket notification channel for immediate state information for media metadata, playback progress, volume etc. The only exception to this is the repeat and shuffle controls which are polled every 30 seconds.
