Trigger automation
Use this action to run the actions of an automation right away, without waiting for its triggersA trigger is a set of values or conditions of a platform that are defined to cause an automation to run. [Learn more]. This is useful for testing an automation, or for reusing one automation from another.
By default the conditions of the automation are skipped, so its actions always run. Turn off Skip conditions if you want the conditions to be checked first.
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 run an automation 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 the automation you want to run.
- From the actions shown for that target, select Trigger automation.
- Optional: turn off Skip conditions if you want the conditions of the automation to be checked.
- 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 automation.trigger. A basic example looks like this:
action: automation.trigger
target:
entity_id: automation.evening_routine
This runs the actions of automation.evening_routine, whatever its conditions say.
To check the conditions first, set skip_condition to false:
action: automation.trigger
target:
entity_id: automation.evening_routine
data:
skip_condition: false

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 automation entity behind that target.
-
Entity: one specific automation entity, such as
automation.living_room. - Device: every automation entity that belongs to a device.
- Area: every automation entity in a room or area.
- Floor: every automation entity on a floor.
- Label: every automation 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 automation runs even when it’s turned off.
- Templates in the automation that use trigger data have nothing to read, because there is no trigger. Keep that in mind if the actions rely on the trigger variable.
- To run the same steps from several places, a script is often a better fit than triggering an automation. See Turn on script.

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.
