Which service should I use as Automation trigger?

[ardeus-ua]

Hello, I've been trying to use this custom component in my automation, but it's not being triggered. Here's how I tried to do this.
automations.yaml:
`

• id: ios_dahua
  alias: IOS Dahua
  trigger:
  • platform: event
    event_type: 'dahua_event'
    action:
    service: notify.ios_iphone_vyacheslav
    data:
    message: "Alarm"
    data:
    push:
    category: camera
    entity_id: camera.dahua
    `
