Bang & Olufsen

The Bang & Olufsen integration enables control of some of the features of certain Bang & Olufsen devices through Home Assistant.

Compatible devices

Devices that have been tested and should work without any trouble are:

and any other Mozart based products. This means all Connected Speakers that have been launched after 2020.

Configuration

To add the Bang & Olufsen device to your Home Assistant instance, use this My button:

Bang & Olufsen can be auto-discovered by Home Assistant. If an instance was found, it will be shown as Discovered. You can then set it up right away.

Manual configuration steps

If it wasn’t discovered automatically, don’t worry! You can set up a manual integration entry:

Browse to your Home Assistant instance.
Go to Settings > Devices & Services.
In the bottom right corner, select the Add Integration button.
From the list, select Bang & Olufsen.
Follow the instructions on screen to complete the setup.

IP Address

The IP address of your device. Can be found by navigating to the device on the Bang & Olufsen app and selecting Settings → About → IP address.

Device model

The model name of your Bang & Olufsen device. This is used to determine some capabilities of the device. If the device is not in the list yet, choose a product similar to yours.

Data updates

The Bang & Olufsen integration uses the Mozart 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.

Supported features

Currently, a single device with a media_player entity is created for each added physical device. For advanced automations, events are fired in Home Assistant.

Media player

A number of features are available through the media player entity:

See current metadata, progress, volume, etc.
Control next/previous, play/pause, shuffle/repeat settings, volume, sound mode, audio and video sources, and more.
Play various media through play_media actions.
Control multiroom audio through Beolink:
- Control with Home Assistant media_player grouping.
- Monitor current Beolink state through media player properties.
- For more advanced usage, custom Beolink services have been defined:
  - Connect or expand to ASE products not available in Home Assistant.
  - Expand sessions to all discovered devices.
  - Connect to, expand to or unexpand devices.
  - Set all connected Beolink devices to standby.

Limitations

Currently, some features of the Mozart platform such as:

Creating timers and alarms
Retrieving detailed alarm and timer information

And more advanced app-centric features such as:

Creating presets
Creating listening positions
Creating sound modes
Creating stereo pairs
Adjusting specific sound settings
Pairing remotes

These features are not available through the API. Some may become available at a later point, but until then the Bang & Olufsen App can be used to configure these settings and features.

Automations

WebSocket notifications received from the device are fired as events in Home Assistant. These can be received by listening to bang_olufsen_websocket_event event types, where device_id or serial_number can be used to differentiate devices.

Getting Deezer URIs

To find Deezer playlist, album URIs, and user IDs for Deezer flows, the Deezer website has to be accessed. When navigating to an album, the URL will look something like: https://www.deezer.com/en/album/ALBUM_ID, and this needs to be converted to: album:ALBUM_ID and the same applies to playlists, which have the format: playlist:PLAYLIST_ID.

Additionally a Deezer user ID can be found at https://www.deezer.com/en/profile/USER_ID by selecting the active user in a web browser.

Getting Tidal URIs

Tidal playlists, album URIs and track IDs are available via the Tidal website. When navigating to an album, the URL will look something like https://listen.tidal.com/album/ALBUM_ID/, and this needs to be converted to album:ALBUM_ID. The same applies to playlists, which have the format playlist:PLAYLIST_ID. Individual tracks can be found by sharing the track and selecting the Copy track link method, which should yield a link of the format https://tidal.com/browse/track/TRACK_ID?u, this can be played by extracting the track id TRACK_ID.

Beolink

Discovered devices and devices in an active Beolink experience are available in the properties of the media_player entity. A device is represented by its friendly name and JID, used for connecting devices.

beolink:
  self: The current device
  leader: Beolink leader (if available)
  listeners: Beolink listeners (if available)
  peers: Beolink peers (if available)
