HTML5 push notification vibration on Android


I have the following yaml automation for a HTML5 push notification.

  alias: Test notify
  description: ''
  - entity_id: input_boolean.automation_test
    from: 'on'
    platform: state
    to: 'off'
  condition: []
  - service: notify.html5_push_notifications
      message: hello world!
      - Philip mobil
        tag: tag-test
        vibrate: 300,100,400
        - action: open
          title: test action title

Im trying to get it to vibrate, but no luck. Ive tried putting the numbers for ms to vibrate in “”, [], {} and ‘’, but no luck. Anyone have any experience with this?

Also, it does not wake up my phone or make any noise, so Im clearly doing something wrong. Any help would be greatly appreciated.

Ever figure this out?

No, still searching for a solution, so if anyone knows…

I’m having same issue with vibrate, If I remove vibrate it’ll come through.

I’m having similar issues, notifications come through but vibration doesn’t work. Is this just unsupported or a bug?
