Perform an action

Performing an action can be done in various ways. For all the different possibilities, have a look at the actions page.

- alias: "Bedroom lights on"
  action: light.turn_on
  target:
    entity_id: group.bedroom
  data:
    brightness: 100

Activate a scene

Scripts may also use a shortcut syntax for activating scenesScenes capture the states you want certain entities to be. For example, a scene can specify that light A should be turned on and light B should be bright red. [Learn more] instead of calling the scene.turn_on action.

- scene: scene.morning_living_room

Variables

The variables actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] allows you to set/override variables that will be accessible by templates in actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] after it. See also script variables for how to define variables accessible in the entire script.

- alias: "Set variables"
  variables:
    entities: 
      - light.kitchen
      - light.living_room
    brightness: 100
- alias: "Control lights"
  action: light.turn_on
  target:
    entity_id: "{{ entities }}"
  data:
    brightness: "{{ brightness }}"

Variables can be templated.

- alias: "Set a templated variable"
  variables:
    blind_state_message: "The blind is {{ states('cover.blind') }}."
- alias: "Notify about the state of the blind"
  action: notify.mobile_app_iphone
  data:
    message: "{{ blind_state_message }}"

Scope of variables

Variables have local scope. This means that if a variable is changed in a nested sequence block, that change will not be visible in an outer sequence block.

Inside the if sequence the variables actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] will only alter the people variable for that sequence.

sequence:
  # Set the people variable to a default value
  - variables:
      people: 0
  # Try to increment people if Paulus is home
  - if:
      - condition: state
        entity_id: device_tracker.paulus
        state: "home"
    then:
      # At this scope and this point of the sequence, people == 0
      - variables:
          people: "{{ people + 1 }}"
      # At this scope, people will now be 1 ...
      - action: notify.notify
        data:
          message: "There are {{ people }} people home" # "There are 1 people home"
  # ... but at this scope it will still be 0
  - action: notify.notify
    data:
      message: "There are {{ people }} people home" # "There are 0 people home"

Test a condition

While executing a script you can add a condition in the main sequence to stop further execution. When a condition does not return true, the script will stop executing. For documentation on the many different conditions refer to the conditions page.

# If paulus is home, continue to execute the script below these lines
- alias: "Check if Paulus is home"
  condition: state
  entity_id: device_tracker.paulus
  state: "home"

condition can also be a list of conditions and execution will then only continue if ALL conditions return true.

- alias: "Check if Paulus ishome AND temperature is below 20"
  conditions:
    - condition: state
      entity_id: "device_tracker.paulus"
      state: "home"
    - condition: numeric_state
      entity_id: "sensor.temperature"
      below: 20

Wait for time to pass (delay)

Delays are useful for temporarily suspending your script and start it at a later moment. We support different syntaxes for a delay as shown below.

# Seconds
# Waits 5 seconds
- alias: "Wait 5s"
  delay: 5

# HH:MM
# Waits 1 hour
- delay: "01:00"

# HH:MM:SS
# Waits 1.5 minutes
- delay: "00:01:30"

# Supports milliseconds, seconds, minutes, hours, days
# Can be used in combination, at least one required
# When using milliseconds, consider that delay as *at least* X milliseconds. It won´t be exact.
# Waits 1 minute
- delay:
    minutes: 1

All forms accept templates.

# Waits however many minutes input_number.minute_delay is set to
- delay: "{{ states('input_number.minute_delay') | multiply(60) | int }}"

Wait

These actionsActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] allow a script to wait for entities in the system to be in a certain state as specified by a template, or some event to happen as expressed by one or more triggers.

Wait for a template

This actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] evaluates the template, and if true, the script will continue. If not, then it will wait until it is true.

The template is re-evaluated whenever an entity ID that it references changes state. If you use non-deterministic functions like now() in the template it will not be continuously re-evaluated, but only when an entity ID that is referenced is changed. If you need to periodically re-evaluate the template, reference a sensor from the Time and Date integration that will update minutely or daily.

# Wait until media player is stopped
- alias: "Wait until media player is stopped"
  wait_template: "{{ is_state('media_player.floor', 'stop') }}"

Wait for a trigger

This actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] can use the same triggers that are available in an automation’s trigger section. See Automation Trigger. The script will continue whenever any of the triggers fires. All previously defined trigger variables, variables and script variables are passed to the trigger.

# Wait for a custom event or light to turn on and stay on for 10 sec
- alias: "Wait for MY_EVENT or light on"
  wait_for_trigger:
    - trigger: event
      event_type: MY_EVENT
    - trigger: state
      entity_id: light.LIGHT
      to: "on"
      for: 10

Wait timeout

With both types of waits it is possible to set a timeout after which the script will continue its execution if the condition/event is not satisfied. Timeout has the same syntax as delay, and like delay, also accepts templates.

# Wait for sensor to change to 'on' up to 1 minute before continuing to execute.
- wait_template: "{{ is_state('binary_sensor.entrance', 'on') }}"
  timeout: "00:01:00"

You can also get the script to abort after the timeout by using optional continue_on_timeout: false.

# Wait for IFTTT event or abort after specified timeout.
- wait_for_trigger:
    - trigger: event
      event_type: ifttt_webhook_received
      event_data:
        action: connected_to_network
  timeout:
    minutes: "{{ timeout_minutes }}"
  continue_on_timeout: false

Without continue_on_timeout: false the script will always continue since the default for continue_on_timeout is true.

Wait variable

After each time a wait completes, either because the condition was met, the event happened, or the timeout expired, the variable wait will be created/updated to indicate the result.

This can be used to take different actions based on whether or not the condition was met, or to use more than one wait sequentially while implementing a single timeout overall.

# Take different actions depending on if condition was met.
- wait_template: "{{ is_state('binary_sensor.door', 'on') }}"
  timeout: 10
- if:
    - "{{ not wait.completed }}"
  then:
    - action: script.door_did_not_open
  else:
    - action: script.turn_on
      target:
        entity_id:
          - script.door_did_open
          - script.play_fanfare

# Wait a total of 10 seconds.
- wait_template: "{{ is_state('binary_sensor.door_1', 'on') }}"
  timeout: 10
  continue_on_timeout: false
- action: switch.turn_on
  target:
    entity_id: switch.some_light
- wait_for_trigger:
    - trigger: state
      entity_id: binary_sensor.door_2
      to: "on"
      for: 2
  timeout: "{{ wait.remaining }}"
  continue_on_timeout: false
- action: switch.turn_off
  target:
    entity_id: switch.some_light

Fire an event

This actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] allows you to fire an event. Events can be used for many things. It could trigger an automationAutomations in Home Assistant allow you to automatically respond to things that happen in and around your home. [Learn more] or indicate to another integration that something is happening. For instance, in the below example it is used to create an entry in the logbook.

- alias: "Fire LOGBOOK_ENTRY event"
  event: LOGBOOK_ENTRY
  event_data:
    name: Paulus
    message: is waking up
    entity_id: device_tracker.paulus
    domain: light

You can also use event_data to fire an event with custom data. This could be used to pass data to another script awaiting an event trigger.

The event_data accepts templates.

- event: MY_EVENT
  event_data:
    name: myEvent
    customData: "{{ myCustomVariable }}"

Raise and Consume Custom Events

The following automationAutomations in Home Assistant allow you to automatically respond to things that happen in and around your home. [Learn more] example shows how to raise a custom event called event_light_state_changed with entity_id as the event data. The actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] part could be inside a script or an automationAutomations in Home Assistant allow you to automatically respond to things that happen in and around your home. [Learn more].

- alias: "Fire Event"
  triggers:
    - trigger: state
      entity_id: switch.kitchen
      to: "on"
  actions:
    - event: event_light_state_changed
      event_data:
        state: "on"

The following automationAutomations in Home Assistant allow you to automatically respond to things that happen in and around your home. [Learn more] example shows how to capture the custom event event_light_state_changed with an Event Automation Trigger, and retrieve corresponding entity_id that was passed as the event trigger data, see Available-Trigger-Data for more details.

- alias: "Capture Event"
  triggers:
    - trigger: event
      event_type: event_light_state_changed
  actions:
    - action: notify.notify
      data:
        message: "kitchen light is turned {{ trigger.event.data.state }}"

Repeat a group of actions

This actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] allows you to repeat a sequence of other actionsActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more]. Nesting is fully supported. There are three ways to control how many times the sequence will be run.

Counted repeat

This form accepts a count value. The value may be specified by a template, in which case the template is rendered when the repeat step is reached.

script:
  flash_light:
    mode: restart
    sequence:
      - action: light.turn_on
        target:
          entity_id: "light.{{ light }}"
      - alias: "Cycle light 'count' times"
        repeat:
          count: "{{ count|int * 2 - 1 }}"
          sequence:
            - delay: 2
            - action: light.toggle
              target:
                entity_id: "light.{{ light }}"
  flash_hallway_light:
    sequence:
      - alias: "Flash hallway light 3 times"
        action: script.flash_light
        data:
          light: hallway
          count: 3

For each

This repeat form accepts a list of items to iterate over. The list of items can be a pre-defined list, or a list created by a template.

The sequence is ran for each item in the list, and current item in the iteration is available as repeat.item.

The following example will turn a list of lights:

repeat:
  for_each:
    - "living_room"
    - "kitchen"
    - "office"
  sequence:
    - action: light.turn_off
      target:
        entity_id: "light.{{ repeat.item }}"

Other types are accepted as list items, for example, each item can be a template, or even an mapping of key/value pairs.

repeat:
  for_each:
    - language: English
      message: Hello World
    - language: Dutch
      message: Hallo Wereld
  sequence:
    - action: notify.phone
      data:
        title: "Message in {{ repeat.item.language }}"
        message: "{{ repeat.item.message }}!"

While loop

This form accepts a list of conditions (see conditions page for available options) that are evaluated before each time the sequence is run. The sequence will be run as long as the condition(s) evaluate to true.

script:
  do_something:
    sequence:
      - action: script.get_ready_for_something
      - alias: "Repeat the sequence AS LONG AS the conditions are true"
        repeat:
          while:
            - condition: state
              entity_id: input_boolean.do_something
              state: "on"
            # Don't do it too many times
            - condition: template
              value_template: "{{ repeat.index <= 20 }}"
          sequence:
            - action: script.something

The while also accepts a shorthand notation of a template condition. For example:

- repeat:
    while: "{{ is_state('sensor.mode', 'Home') and repeat.index < 10 }}"
    sequence:
    - ...

Repeat until

This form accepts a list of conditions that are evaluated after each time the sequence is run. Therefore the sequence will always run at least once. The sequence will be run until the condition(s) evaluate to true.

automation:
  - triggers:
      - trigger: state
        entity_id: binary_sensor.xyz
        to: "on"
    conditions:
      - condition: state
        entity_id: binary_sensor.something
        state: "off"
    actions:
      - alias: "Repeat the sequence UNTIL the conditions are true"
        repeat:
          sequence:
            # Run command that for some reason doesn't always work
            - action: shell_command.turn_something_on
            # Give it time to complete
            - delay:
                milliseconds: 200
          until:
            # Did it work?
            - condition: state
              entity_id: binary_sensor.something
              state: "on"

until also accepts a shorthand notation of a template condition. For example:

- repeat:
    until: "{{ is_state('device_tracker.iphone', 'home') }}"
    sequence:
    - ...

Repeat loop variable

A variable named repeat is defined within the repeat actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] (i.e., it is available inside sequence, while & until.) It contains the following fields:

If-then

This actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] allow you to conditionally (if) run a sequence of actions (then) and optionally supports running other sequence when the condition didn’t pass (else).

script:
  - if:
      - alias: "If no one is home"
        condition: state
        entity_id: zone.home
        state: 0
    then:
      - alias: "Then start cleaning already!"
        action: vacuum.start
        target:
          area_id: living_room
    # The `else` is fully optional and can be omitted
    else:
      - action: notify.notify
        data:
          message: "Skipped cleaning, someone is home!"

This actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] supports nesting, however, if you find yourself using nested if-then actions in the else part, you may want to consider using choose instead.

Choose a group of actions

This actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] allows you to select a sequence of other actionsActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] from a list of sequences. Nesting is fully supported.

Each sequence is paired with a list of conditions. (See the conditions page for available options and how multiple conditions are handled.) The first sequence whose conditions are all true will be run. An optional default sequence can be included which will be run only if none of the sequences from the list are run.

An optional alias can be added to each of the sequences, excluding the default sequence.

The choose actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] can be used like an “if/then/elseif/then…/else” statement. The first conditions/sequence pair is like the “if/then”, and can be used just by itself. Or additional pairs can be added, each of which is like an “elif/then”. And lastly, a default can be added, which would be like the “else.”

# Example with "if", "elif" and "else"
automation:
  - triggers:
      - trigger: state
        entity_id: input_boolean.simulate
        to: "on"
    mode: restart
    actions:
      - choose:
          # IF morning
          - conditions:
              - condition: template
                value_template: "{{ now().hour < 9 }}"
            sequence:
              - action: script.sim_morning
          # ELIF day
          - conditions:
              - condition: template
                value_template: "{{ now().hour < 18 }}"
            sequence:
              - action: light.turn_off
                target:
                  entity_id: light.living_room
              - action: script.sim_day
        # ELSE night
        default:
          - action: light.turn_off
            target:
              entity_id: light.kitchen
          - delay:
              minutes: "{{ range(1, 11)|random }}"
          - action: light.turn_off
            target:
              entity_id: all

conditions also accepts a shorthand notation of a template condition. For example:

automation:
  - triggers:
      - trigger: state
        entity_id: input_select.home_mode
    actions:
      - choose:
          - conditions: >
              {{ trigger.to_state.state == 'Home' and
                 is_state('binary_sensor.all_clear', 'on') }}
            sequence:
              - action: script.arrive_home
                data:
                  ok: true
          - conditions: >
              {{ trigger.to_state.state == 'Home' and
                 is_state('binary_sensor.all_clear', 'off') }}
            sequence:
              - action: script.turn_on
                target:
                  entity_id: script.flash_lights
              - action: script.arrive_home
                data:
                  ok: false
          - conditions: "{{ trigger.to_state.state == 'Away' }}"
            sequence:
              - action: script.left_home

More choose can be used together. This is the case of an IF-IF.

The following example shows how a single automationAutomations in Home Assistant allow you to automatically respond to things that happen in and around your home. [Learn more] can control entities that aren’t related to each other but have in common the same trigger.

When the sun goes below the horizon, the porch and garden lights must turn on. If someone is watching the TV in the living room, there is a high chance that someone is in that room, therefore the living room lights have to turn on too. The same concept applies to the studio room.

# Example with "if" and "if"
automation:

            - conditions:
                - condition: state
                  entity_id: binary_sensor.studio_pc
                  state: "on"
              sequence:
                - action: light.turn_on
                  data:
                    brightness: 255
                    color_temp: 366
                  target:
                    entity_id: light.studio

Grouping actions

The sequence actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] allows you to group multiple actionsActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] together. Each action will be executed in order, meaning the next action will only be executed after the previous action has been completed.

Grouping actions in a sequence can be useful when you want to be able to collapse related groups in the user interface for organizational purposes.

Combined with the parallel action, it can also be used to run multiple groups of actions in a sequence in parallel.

In the example below, two separate groups of actions are executed in sequence, one for turning on devices, the other for sending notifications. Each group of actions is executed in order, this includes the actions in each group and the groups themselves. In total, four actions are executed, one after the other.

automation:
  - triggers:
      - trigger: state
        entity_id: binary_sensor.motion
        to: "on"
    actions:
      - alias: "Turn on devices"
        sequence:
          - action: light.turn_on
            target:
              entity_id: light.ceiling
          - action: siren.turn_on
            target:
              entity_id: siren.noise_maker
      - alias: "Send notifications"
        sequence:
          - action: notify.person1
            data:
              message: "The motion sensor was triggered!"
          - action: notify.person2
            data:
              message: "Oh oh, someone triggered the motion sensor..."

Parallelizing actions

By default, all sequences of actionsActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] in Home Assistant run sequentially. This means the next actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] is started after the current action has been completed.

This is not always needed, for example, if the sequence of actions doesn’t rely on each other and order doesn’t matter. For those cases, the parallel action can be used to run the actionsActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] in the sequence in parallel, meaning all the actionsActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] are started at the same time.

The following example shows sending messages out at the same time (in parallel):

automation:
  - triggers:
      - trigger: state
        entity_id: binary_sensor.motion
        to: "on"
    actions:
      - parallel:
          - action: notify.person1
            data:
              message: "These messages are sent at the same time!"
          - action: notify.person2
            data:
              message: "These messages are sent at the same time!"

It is also possible to run a group of actions sequentially inside the parallel actions. The example below demonstrates that:

script:
  example_script:
    sequence:
      - parallel:
          - sequence:
              - wait_for_trigger:
                  - trigger: state
                    entity_id: binary_sensor.motion
                    to: "on"
              - action: notify.person1
                data:
                  message: "This message awaited the motion trigger"
          - action: notify.person2
            data:
              message: "I am sent immediately and do not await the above action!"

Some of the caveats of running actionsActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] in parallel:

• There is no order guarantee. The actionsActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] will be started in parallel, but there is no guarantee that they will be completed in the same order.
• If one actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] fails or errors, the other actionsActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] will keep running until they too have finished or errored.
• Variables created/modified in one parallelized actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] are not available in another parallelized actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more]. Each step in a parallelized has its own scope.

Stopping a script sequence

It is possible to halt a script sequence at any point and return script responses using the stop actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more].

The stop actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] takes a text as input explaining the reason for halting the sequence. This text will be logged and shows up in the automationsAutomations in Home Assistant allow you to automatically respond to things that happen in and around your home. [Learn more] and script traces.

stop can be useful to halt a script halfway through a sequence when, for example, a condition is not met.

- stop: "Stop running the rest of the sequence"

To return a response from a script, use the response_variable option. This option expects the name of the variable that contains the data to return. The response data must contains a mapping of key/value pairs.

- stop: "Stop running the rest of the sequence"
  response_variable: "my_response_variable"

There is also an error option, to indicate we are stopping because of an unexpected error. It stops the sequence as well, but marks the automationAutomations in Home Assistant allow you to automatically respond to things that happen in and around your home. [Learn more] or script as failed to run.

- stop: "Well, that was unexpected!"
  error: true

Continuing on error

By default, a sequence of actionsActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] will be halted when one of the actionsActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] in that sequence encounters an error. The automationAutomations in Home Assistant allow you to automatically respond to things that happen in and around your home. [Learn more] or script will be halted, an error is logged, and the automationAutomations in Home Assistant allow you to automatically respond to things that happen in and around your home. [Learn more] or script run is marked as errored.

Sometimes these errors are expected, for example, because you know the action you perform can be problematic at times, and it doesn’t matter if it fails. You can set continue_on_error for those cases on such an actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more].

The continue_on_error is available on all actionsActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] and is set to false. You can set it to true if you’d like to continue the actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] sequence, regardless of whether that actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] encounters an error.

The example below shows the continue_on_error set on the first actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more]. If it encounters an error; it will continue to the next actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more].

- alias: "If this one fails..."
  continue_on_error: true
  action: notify.super_unreliable_service_provider
  data:
    message: "I'm going to error out..."

- alias: "This one will still run!"
  action: persistent_notification.create
  data:
    title: "Hi there!"
    message: "I'm fine..."

Please note that continue_on_error will not suppress/ignore misconfiguration or errors that Home Assistant does not handle.

Disabling an action

Every individual actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] in a sequence can be disabled, without removing it. To do so, add enabled: false to the actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more]. For example:

# Example script with a disabled action
script:
  example_script:
    sequence:
      # This action will not run, as it is disabled.
      # The message will not be sent.
      - enabled: false
        alias: "Notify that the ceiling light is being turned on"
        action: notify.notify
        data:
          message: "Turning on the ceiling light!"

      # This action will run, as it is not disabled
      - alias: "Turn on the ceiling light"
        action: light.turn_on
        target:
          entity_id: light.ceiling

Actions can also be disabled based on limited templates or blueprint inputs.

blueprint:
  input:
    input_boolean:
      name: Boolean
      selector: 
        boolean:

  actions:
    - delay: 0:35
      enabled: !input input_boolean

Respond to a conversation

The set_conversation_response script actionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called sequence. [Learn more] allows returning a custom response when an automationAutomations in Home Assistant allow you to automatically respond to things that happen in and around your home. [Learn more] is triggered by a conversation engine, for example a voice assistant. The conversation response can be templated.

# Example of a templated conversation response resulting in "Testing 123"
- variables:
    my_var: "123"
- set_conversation_response: "{{ 'Testing ' + my_var }}":

The response is handed to the conversation engine when the automationAutomations in Home Assistant allow you to automatically respond to things that happen in and around your home. [Learn more] finishes. If the set_conversation_response is executed multiple times, the most recent response will be handed to the conversation engine. To clear the response, set it to None:

# Example of a clearing a conversation response
set_conversation_response: ~

If the automationAutomations in Home Assistant allow you to automatically respond to things that happen in and around your home. [Learn more] was not triggered by a conversation engine, the response will not be used by anything.
