Turn down group volume
Use this action to turn down the volume of a HEOS group by a step, while keeping the relative balance between the group members. You can call it on any player that is joined to the group.
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 turn down the group volume from an automation or a script:
- Go to Settings > Automations & scenes.
- Open an existing automation or script, or select Create automation > Create new automation.
- 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.
- In the Then do section, select Add action.
- Select what you want to control. Under By target (see Targets), select a HEOS media player that is joined to the group.
- From the actions shown for that target, select Turn down group volume.
- Select Save.

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 heos.group_volume_down. A basic example looks like this:
action: heos.group_volume_down
target:
entity_id: media_player.kitchen
This turns down the volume of the group that media_player.kitchen belongs to.
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
- The step keeps the relative volume of each member, so the group stays in balance.
- To set an exact level instead of stepping, use Set group volume.
