Notify when open zwave is ready

Hi,

how can I get a notification when open zwave is ready.
voor the build in zwave from hassio I already have the script
but for open zwave I cant find the correct code.

.

- id: open zwave ready
  alias: open zwave ready
  trigger:
  - event_type: ???????????????????
    platform: event
  action:
  - data:
      message: open zWave ready
      title: open zWave ready
    service: notify.xxxxxxxxxxxxx
  initial_state: true
