Beolink expand

The Beolink expand action adds one or more devices to the Beolink experience that the target device is hosting.

This is useful for extending the audio that is already playing on a device to other rooms.

Using this action from the user interface

If you prefer building automations and scripts visually, Home Assistant walks you through this action step by step. You pick what to target, tweak a few options, and save. No YAML knowledge required.

To expand a Beolink experience from an automation or a script:

1. Go to Settings > Automations & scenes.
2. Open an existing automation or script, or select Create automation > Create new automation.
3. If you’re setting up a new automation, add a trigger in the When section. Scripts don’t need a trigger. They run when something else calls them.
4. In the Then do section, select Add action.
5. Select what you want to control. Under By target (see Targets), select the Bang & Olufsen device you want to control. You can also select an area, a device, or a label.
6. From the actions shown for that target, select Beolink expand.
7. Enable All discovered, or enter the Beolink JIDs to add. Set only one of the two.
8. Select Save.

Options in the UI

Set either All discovered or Beolink JIDs, not both.

Using this action in YAML

If you work directly in YAML, or you want to know exactly what Home Assistant does under the hood, this section has the technical reference. It lists the field names you use in YAML, their types, and which ones are required.

In YAML, refer to this action as bang_olufsen.beolink_expand. A basic example looks like this:

action: bang_olufsen.beolink_expand
target:
  entity_id: media_player.beosound_balance_12345678
data:
  all_discovered: true

This expands the experience to every device the target device has discovered.

Targets of the action

This action requires a target. The target is the object of the action. You can point the action at a single entityAn entity represents a sensor, actor, or function in Home Assistant. Entities are used to monitor physical properties or to control other entities. An entity is usually part of a device or a service. [Learn more], a device, an area, a floor, or a label, and Home Assistant will run the action on every matching media_player entity behind that target.

• Entity: one specific media_player entity, such as media_player.living_room.
• Device: every media_player entity that belongs to a device.
• Area: every media_player entity in a room or area.
• Floor: every media_player entity on a floor.
• Label: every media_player entity that shares a label.

You can also select different target types in one action. For example, you can add a specific entity and an area as targets in the same action to run the action on both of them at once.

Good to know

• Calling the media_player.join action with the entity IDs of other Bang & Olufsen media players in group_members has the same effect.
