Basic Notifications
The iOS notify platform accepts the standard title, message and target parameters. The iOS notify platform supports targets as services. Assuming that you did not set a name when configuring the platform you should find all your registered and notification-enabled iOS devices available as notify targets as services with names prefixed “notify.ios_” and then the device name you entered at setup.
Notes:
- 
    
titleonly displays on Apple Watch and iOS 10 devices. - 
    
targetcan be used to specific a single device using its PushID, found inios.conf. The preferred way of providing a target is through a target specific notify service. 
  
  A push notification showing all of the basic options title and message as well as subtitle and actions.
Enhancing basic notifications
Badge
You can set the icon badge in the payload:
automation:
  - alias: Notify iOS app
    trigger:
      ...
    action:
      service: notify.ios_<your_device_id_here>
      data:
        message: "Something happened at home!"
        data:
          push:
            badge: 5
Subtitle
iOS 10 supports a subtitle in addition to the title:
automation
  - alias: Notify iOS app
    trigger:
      ...
    action:
      service: notify.ios_<your_device_id_here>
      data:
        message: "Something happened at home!"
        data:
          subtitle: "Subtitle goes here"
Sending notifications to multiple phones
To send notifications to multiple phones, create a notification group:
notify:
  - name: NOTIFIER_NAME
    platform: group
    services:
      - service: ios_iphone_one
      - service: ios_iphone_two
Now, you can send notifications to everyone in the group using:
  automation:
    - alias: Notify iOS app
      trigger:
        ...
      action:
        service: notify.NOTIFIER_NAME
        data:
          message: "Something happened at home!"
          data:
            push:
              badge: 5
