Event received

The Event received trigger runs an automation when a physical event entity — such as a doorbell, a remote control button, or a motion sensor — detects a specific type of event. Use it when you want to react to a particular event type, like a doorbell ring or a double press, rather than any state change on the entity.

Labs

Requires the Purpose-specific triggers and conditions Labs preview feature. Enable it at Settings > System > Labs.

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 this trigger 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), select the area, floor, device, label, or entity you want to monitor.
  5. From the triggers shown for that target, select Event received.
  6. Under Event type, select one or more event types you want to match.
  7. Select Save.

Options in the UI

Event type

The event types to trigger on. Select one or more types. The available types depend on the target entity. Required.

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, refer to this trigger as event.received. A basic example looks like this:

TriggerA trigger is a set of values or conditions of a platform that are defined to cause an automation to run. [Learn more]
trigger: event.received
target:
  entity_id: event.front_door_doorbell
options:
  event_type:
    - ring

This fires every time event.front_door_doorbell receives a ring event.

Options in YAML

YAML uses an options mapping for trigger-specific settings.

event_type string Required

One or more event types to match. The available event types depend on the target entity. Use a list for multiple types.

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 event entity behind that target.

  • Entity: one specific event entity, such as event.living_room.
  • Device: every event entity that belongs to a device.
  • Area: every event entity in a room or area.
  • Floor: every event entity on a floor.
  • Label: every event 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 only when the entity receives one of the specified event types. Changes to unavailable or unknown do not fire the trigger.
  • The available event types depend on the entity. For example, a doorbell might support ring, while a remote control might support short_release and long_release.
  • You can select multiple event types in a single trigger to react to any of them.
  • To trigger on any event type from an entity, use the State trigger instead.

Tip

You don’t need to edit YAML to use these examples. Copy a YAML snippet from this page, open the automation editor in Home Assistant, and press Ctrl+V (or Cmd+V on Mac). Home Assistant automatically converts the pasted YAML into the visual editor format, whether it’s a full automation, a single trigger, a condition, or an action.
