What's wrong in my syntax?

I have to say… Yaml isn’t the most straight forward markup I’ve come across…
What am I doing wrong here?

- trigger:
    platform: state
    entity_id: binary_sensor.motion
    to: 'on'
    condition:
      platform: numeric_state
      entity_id: 'sensor.fibaro_system_fgms001zw5_motion_sensor_luminance_2'
      below: 300
      above: 200
    action:
      service: light.turn_on
      entity_id: group.bathroom
      data:
        brightness: 240
        color_name: white
- trigger:
    platform: state
    entity_id: binary_sensor.motion
    to: 'on'
    condition:
      platform: numeric_state
      entity_id: 'sensor.fibaro_system_fgms001zw5_motion_sensor_luminance_2'
      below: 200
      above: 100
    action:
      service: light.turn_on
      entity_id: group.bathroom
      data:
        brightness: 180
        color_name: yellow

Hi,
trigger, condition and action are the 3 “headers” of the automation, so all of them should be in the same level (indentation).
you should create a “main” header called -alias: “reference name”
so something like

- alias: 'disparar full'
  trigger:
    - platform: state
      entity_id: sensor.multisensor_6_motion
      from: 'still'
      to: 'motion'
    - platform: state
      entity_id: sensor.multisensor_6_motion
      from: 'motion'
      to: 'tamper'
    - platform: state
      entity_id: sensor.multisensor_6_motion
      from: 'still'
      to: 'tamper'
    - platform: state
      entity_id: sensor.door
      from: 'closed'
      to: 'open'
  condition: 
    - condition: state
      entity_id: alarm_control_panel.full
      state: 'armed_away'
  action:
    - service: notify.alarme2
      data_template:
        title: Alarm event details
        message: Sensor {{ trigger.to_state.attributes.friendly_name }} triggered - {{ trigger.to_state.state }}.
    - service: alarm_control_panel.alarm_trigger
      entity_id: alarm_control_panel.full
    - service: notify.alarme2
      data:
        title: Full Alarm Event!
        message: Alarm Triggered.
        data: 
          priority: 2
          retry: 30
          expire: 3600

have a look on Automating Home Assistant - Home Assistant and check some examples on Examples - Home Assistant

that is how i did mine.
