Actionable Notifications

Actionable notifications are a unique type of notification as they allow the user to add buttons to the notification which can then send an event to Home Assistant once clicked. This event can then be used in an automation allowing you to perform a wide variety of actions. These notifications can be sent to either iOS or Android but they do have some differences. iOS allows you to attach up to four actions while Android only allows you to attach up to three actions per notification.

Some useful examples of actionable notifications:

A notification is sent whenever motion is detected in your home while you're away or asleep. A "Sound Alarm" action button is displayed alongside the notification, that when tapped, will sound your burglar alarm.
Someone rings your front doorbell. You receive a notification with a live camera stream of the visitor outside along with action buttons to lock or unlock your front door.
Receive a notification whenever your garage door opens with action buttons to open or close the garage.

Actionable notifications allow the user to send a command back to Home Assistant.

If you are using iOS please continue to read below, if you are using Android start from the Android example here.

On iOS notifications can be grouped by category, this allows for different types of notifications from Home Assistant to be placed in a appropriate stacks on the lock screen and even custom summary text to be used on the notification stack. These categories also allow you to create actionable notifications.

Overview of how actionable notifications work on iOS

In advance of sending a notification:

Define a notification category in your Home Assistant configuration which contain 1-4 actions.
At launch iOS app requests notification categories from Home Assistant (can also be done manually in notification settings).

When sending a notification:

Send a notification with data.push.category set to a pre-defined notification category identifier.
Push notification delivered to device.
User opens notification.
Action tapped.
Identifier of action sent back to HA as the actionName property of the event ios.notification_action_fired, along with other metadata such as the device and category name.

How the iOS device and Home Assistant work together to enable actionable notifications.

Definitions

Category - A category represents a type of notification that the app might receive. Think of it as a unique group of actions.
Actions - An action consists of a button title and the information that iOS needs to notify the app when the action is selected. You create separate action objects for distinct action your app supports.

Category parameters

Name	Default	Description
`name:`	required	A friendly name for this category.
`identifier:`	required	A unique identifier for the category. Must be lowercase and have no special characters or spaces.
`actions:`	required	A list of actions. See below.

Actions parameters

Name	Default	Description
`identifier:`	required	A unique identifier for this action. Must be uppercase and have no special characters or spaces. Only needs to be unique to the category, not unique globally.
`title:`	required	The text to display on the button. Keep it short.
`activationMode:`	optional	The mode in which to run the app when the action is performed. Setting this to `foreground` will make the app open after selecting. Default value is `background`.
`authenticationRequired:`	optional	If `true`, the user must unlock the device before the action is performed.
`destructive:`	optional	When `true`, the corresponding button is displayed with a red text color to indicate the action is destructive.
`behavior:`	optional	When `textInput` the system provides a way for the user to enter a text response to be included with the notification. The entered text will be sent back to Home Assistant. Default value is `default`.
`textInputButtonTitle:`	optional*	The button label. Required if `behavior` is `textInput`.
`textInputPlaceholder:`	optional	The placeholder text to show in the text input field. Only used if `behavior` is `textInput`

Here's a fully built example configuration:

ios:
 push:
 categories:
 - name: Alarm
 identifier: 'alarm'
 actions:
 - identifier: 'SOUND_ALARM'
 title: 'Sound Alarm'
 activationMode: 'background'
 authenticationRequired: true
 destructive: true
 behavior: 'default'
 - identifier: 'SILENCE_ALARM'
 title: 'Silence Alarm'
 activationMode: 'background'
 authenticationRequired: true
 destructive: false
 behavior: 'textInput'
 textInputButtonTitle: 'Silencio!'
 textInputPlaceholder: 'Placeholder'

Rather than defining categories using YAML within configuration.yaml, you can create them directly within the Companion App. This can be done from the Notifications page of the App Configuration Menu (accessed from the sidebar menu).

Two variables are available for use in the Hidden preview placeholder and Category summary. %u will give the total number of notifications which have been sent under the same thread ID (see this document for more details). %@ will give the text specified with summary: in the push: section of the notification payload.

Building automations for notification actions

Here is an example automation to send a notification with a category in the payload:

iOS iOS Example

automation:
 - alias: Notify Mobile app
 trigger:
 ...
 action:
 service: notify.mobile_app_<your_device_id_here>
 data:
 title: "Check this out!"
 message: "Something happened at home!"
 data:
 push:
 category: "alarm" # Needs to match the top level identifier you used in the ios configuration
 action_data: # Anything passed in action_data will get echoed back to Home Assistant.
 entity_id: light.test
 my_custom_data: foo_bar

android For Android you create the action directly in the automation action. The below example will give you 2 actions in your notification. The first action will send back an event with the action alarm and the second action will open the URL or load a lovelace view. To load a lovelace view use /lovelace/view replacing view with the defined path for the view you wish to open.

automation:
 - alias: Notify Mobile app
 trigger:
 ...
 action:
 service: notify.mobile_app_<your_device_id_here>
 data:
 message: "Something happened at home!"
 data:
 actions:
 - action: "alarm" # The key you are sending for the event
 title: "Title" # The button title
 - action: "URI" # Must be set to URI if you plan to use a URI
  title: "Open Url"
 uri: "https://google.com" # URL to open when action is selected, can also be a lovelace view

When an action is selected an event named ios.notification_action_fired for iOS and mobile_app_notification_action for Android will be emitted on the Home Assistant event bus. Below is an example payload.

iOS iOS event example

{
 "sourceDeviceName": "Robbie's iPhone 7 Plus",
 "sourceDeviceID": "robbies_iphone_7_plus",
 "actionName": "SOUND_ALARM",
 "sourceDevicePushId": "ab9f02fe-6ac6-47b8-adeb-5dd87b489156",
 "textInput": "",
 "actionData": {}
}

android Android event example

{
 "event_type": "mobile_app_notification_action",
 "data": {
 "action": "KEY_ONE",
 "action_2_title": "Action 2",
 "action_3_title": "Action 3",
 "action_1_title": "Action 1",
 "action_1_key": "KEY_ONE",
 "action_2_key": "KEY_TWO",
 "action_3_key": "KEY_THREE"
 },
 "origin": "REMOTE",
 "time_fired": "2020-02-02T04:45:05.550251+00:00",
 "context": {
 "id": "abc123",
 "parent_id": null,
 "user_id": "123abc"
 }
}

Here's an example automation for the given payload:

iOS iOS Example

automation:
 - alias: Sound the alarm
 trigger:
 platform: event
 event_type: ios.notification_action_fired
 event_data:
 actionName: SOUND_ALARM
 action:
 ...

android Android Example

automation:
 - alias: Sound the alarm
 trigger:
 platform: event
 event_type: mobile_app_notification_action
 event_data:
 action: alarm
 action:
 ...

Notes iOS :

textInput will only exist if behavior was set to textInput.
actionData is a dictionary with parameters passed in the action_data dictionary of the push dictionary in the original notification.
When adding or updating push categories in configuration.yaml be sure to update push settings within the Home Assistant iOS app. This can be found within the Notifications page of the App Configuration menu (accessed from the sidebar menu). You may have to exit the Notifications page and reopen it before new categories are shown. If they are still not listed, restart the Home Assistant Companion App.

Compatibility with different devices

iOS iOS Specific

iOS 13 and later

All devices support notification expanding by performing a right to left swipe and pressing 'View' in the lock screen or pressing and holding, but on 3D Touch-enabled devices you may still need to apply some force to do it. If you're not in the lock screen, you can also pull the notification down to expand it.

Prior to iOS 13

For devices that support 3D Touch - a firm press on the notification will expand it, showing the action buttons underneath. Supported devices include the iPhone 6S, iPhone 6S Plus, iPhone 7, iPhone 7 Plus, iPhone 8, iPhone 8 Plus, iPhone X, iPhone XS and iPhone XS Max. If not in lock screen, you can also pull the notification down to expand it.
For devices that do not support "3D Touch" (such as the iPhone 6 and below, iPhone SE, iPhone XR and iPads), you perform a left to right swipe on the notification, then tap on the 'View' button. This will expand the notification and show the relevant action buttons underneath. If not in lock screen, you need to pull the notification down to expand it.
