HASS start event never triggered

This is my automation that should be triggered on HASS starting, but it seems that it is never fired … why?

- id: 'ha_start'
  alias: HA start
  trigger:
  - platform: homeassistant
    event: start
  action:
    service: timer.start
    entity_id: timer.ha_start

Scratch that, its the old way, see below.

This is what I have (and working both for start and shutdown):

  alias: 'HASS.Startup'
  trigger:
    platform: homeassistant
    event: start
 
  action:
    service: notify.EventGhost
    data:
      message: 'hass.start'

I am gonna guess that there is something amiss in your “action”.

Mine it’s a very strange behaviour… I’ve nothing also in the logbook, seems that HASS it’s never restarted.
