Vacuum returned to dock

The Vacuum returned to dock trigger fires when your vacuum docks at its charging station. Use it to automate notifications or actions when cleaning has finished.

This is a good fit when you want to send a completion message, reset a cleaning status helper, or start another task only after the robot is safely back on the charger.

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. From the search box, search for and select Vacuum: Vacuum returned to dock.
5. Under Targets, choose a single vacuum, an area, floor, or multiple vacuums.
6. Under Trigger when, pick Each, First, or All to control how the trigger fires when more than one vacuum is targeted.
7. Under For at least, enter how long the vacuum must stay docked before the trigger fires.
8. Select Save.

Options in the UI

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 vacuum.docked. A basic example looks like this:

trigger: vacuum.docked
target:
  entity_id:
    - vacuum.upstairs
    - vacuum.downstairs
options:
  behavior: last

This example fires after both vacuums have docked.

Options in YAML

YAML sometimes provides additional options for more complex use cases that are not available through the UI.

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 vacuum entity behind that target.

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

Behavior with multiple targets

When you target more than one entity (or select an area, floor, or label that contains several), the Trigger when option controls how the trigger responds:

• Each (default): the trigger fires every time any one of the targeted entities transitions. For example, if you monitor three motion sensors in the living room and someone walks past sensor 1, the automation fires. When they walk past sensor 2 a moment later, it fires again. Every individual event counts.
• First: the trigger fires only on the first transition in the targeted group, then waits until all targeted entities have reset before it fires again. For example, if you monitor the same three motion sensors, the automation fires when the first one picks up movement (someone entered the room). The other two firing afterward are ignored, so you get one notification per “someone walked in” event instead of three.
• All: the trigger fires only after the last targeted entity in the group has fired, meaning all of them are now in the expected state. For example, if you monitor the lights in the living room, bedroom, and hallway, the automation fires only once all three have turned off. This is useful for scenarios like “start the robot vacuum only after every light on the floor is off,” so you know the room is truly empty.

Good to know

• This trigger fires only on a real transition to docked.
• If a vacuum comes back online from unavailable or unknown, that does not count as docking.

Automation: send a notification when cleaning is finished

When the vacuum docks, the cleaning run is usually complete. This automation sends a quick message so you know the robot is done and back on the charger.

• Trigger: Vacuum returned to dock
• Target: Downstairs vacuum
• Action: Notify mobile app

alias: "Vacuum finished cleaning"
triggers:
  - trigger: vacuum.docked
    target:
      entity_id: vacuum.downstairs
actions:
  - action: notify.mobile_app_phone
    data:
      title: "Vacuum finished"
      message: "The downstairs vacuum returned to its dock."
