Philips Hue bulb as notification

Configuration
1

I have a Philips Hue Zigbee bulb I’d like to use for a notification.
In Zigbee2MQTT there are some effects:

Even when the bulb state is ‘off’ and I press ‘blink’ in the Zigbee2MQTT GUI, the bulb goes on for a short time (kind of flash) and goes out again to 0% brightness.
If the bulb in on for 25% brightness, and I activate ‘blink’ by Zigbee2MQTT GUI, the bulb blinks 1 time and goes back to 25%.
So far so good.
In automations I have to use the service ‘light_on’ in order to be able to select an effect.
When the bulb is ‘off’ (brightness 0 %) and the ‘blink’ is given by the automation, the bulb remains at 50 % brightness. For 25% on it remains 25%.
Why does this happen and how to solve this?
This is the automation made by the automation GUI of HA:

alias: New Automation
  description: ''
  trigger:
  - platform: state
    entity_id: binary_sensor.bladibladi
    to: 'off'
  condition: []
  action:
  - service: light.turn_on
    data:
      effect: blink
    target:
      entity_id: light.lamp_zithoek_raam
  mode: single

You call the service light.turn_on, so not surprising if it remains on.

The way I found to do this, is this way:

    action:
      - service: mqtt.publish
        data:
          topic: zigbee2mqtt/0x0017870102aef297/set
          payload: '{"effect":"blink"}'

Change the ID in topic to your device. It seems it also accepts the friendly name.
