Calendar event ended

The Calendar event ended trigger fires when a calendar event ends. You can also set up the trigger to fire before or after the end of the event.

Use it to automate actions based on the end of a calendar event.

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 Calendar event ended.
5. Under Targets (see Targets), select Add target and pick what to watch. Select the calendar entity with the event that you want to watch. You can also select a device or a label, for example.
6. Under Offset, you can enter the time from the end of the event when the trigger will fire. If you want the trigger to fire at the ending time of the event, skip this step and the next one.
7. If you entered an offset, under Offset type, select one of the following:
   • Before if you want the trigger to fire before the end of the event.
   • After if you want the trigger to fire after the end of the event.
8. 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, refer to this trigger as calendar.event_ended. A basic example looks like this:

trigger: calendar.event_ended
target:
  entity_id: calendar.personal
options:
  offset:
    minutes: 30
  offset_type: after

This fires 30 minutes after the end of an event in calendar.personal.

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 calendar entity behind that target.

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

• Note that calendars are read once every 15 minutes. When testing, make sure you do not plan events less than 15 minutes away from the current time, or your triggerA trigger is a set of values or conditions of a platform that are defined to cause an automation to run. [Learn more] might not fire.
• You can also create an automation based on the state of a calendar 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 calendar trigger should not generally use automation mode single to ensure the trigger can fire when multiple events end at the same time. For example, use queued or parallel instead.
• In YAML, you can also set up other variables for calendar triggers. See Automation Trigger Variables: Calendar to check the available trigger data.
