Media player volume changed

The Media player volume changed trigger fires when a media player’s volume changes and the new value matches the threshold rule you set. Use it when you want to react to a new volume level, not just to playback starting or stopping.

Use Media player volume changed to adjust lights when volume gets high, send a notification when volume drops too low, or react to any change for logging and other routines.

Using this trigger from the user interface

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

To use Media player volume changed in an automation:

1. Go to Settings > Automations & scenes.
2. Open an existing automation, or select Create automation > Create new automation.
3. In the When section, select Add trigger.
4. Select what you want to monitor. Under By target (see Targets), pick the media player you want to watch. You can also select an area, a floor, a device, or a label.
5. From the triggers shown for that target, select Media player volume changed.
6. Under Threshold, set what kind of volume change should fire the trigger:
   • Select Any change to fire on any volume change.
   • Select Above or Below to fire when the new volume is above or below a threshold.
   • Select In range or Outside range to fire when the new volume lands inside or outside a range.
   • For each option, you can enter a fixed percentage from 0 to 100, or use an input_number, number, or sensor entity with % as the unit.
7. Select Save.

Using this trigger 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, this trigger is referred to as media_player.volume_changed. A basic example looks like this:

trigger: media_player.volume_changed
target:
  entity_id: media_player.living_room_receiver
options:
  threshold:
    type: above
    value:
      number: 60

This fires when the receiver volume changes to a value above 60%.

To use a helperA helper is a virtual entity you create inside Home Assistant. It is not backed by a physical device. Helpers store values, track state, or do calculations that your automations and dashboards need. [Learn more] you created separately as a dynamic threshold:

trigger: media_player.volume_changed
target:
  entity_id: media_player.living_room_receiver
options:
  threshold:
    type: above
    value:
      entity: input_number.media_volume_limit

Targets of the trigger

This trigger requires a target. The target is the object that Home Assistant will watch. You can select 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 as a target, and Home Assistant will watch 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 trigger. For example, you can add a specific entity and an area as targets in the same trigger to monitor both of them at once.

Good to know

• This trigger fires when the new volume matches the threshold rule. If you only want to react when volume crosses a level, use Media player volume crossed threshold.
• Threshold helper entities must use % as the unit. If you want to adjust the limit from the UI, create a helperA helper is a virtual entity you create inside Home Assistant. It is not backed by a physical device. Helpers store values, track state, or do calculations that your automations and dashboards need. [Learn more] separately first.
• Media players that are unavailable or unknown do not provide usable volume values until they report a supported state again.
