How do I match on new_state object properties in automation trigger

Configuration

Home assistant logs the following event:

  }
}

I want trigger to fire only when new state is rotate_right. I’ve tried

trigger:
  - platform: event
    event_type: state_changed
    event_data: 
      entity_id: sensor.cube_action
      new_state:
        cube_action: rotate_right

and

trigger:
  - platform: event
    event_type: state_changed
    event_data: 
      entity_id: sensor.cube_action
      new_state: { 'cube_action': 'rotate_right' }

But it doesn’t work (automation never triggers). If I remove new_state filter everything works but it matches other action events. new_state seems to be some kind of object, how to match on its properties correctly?

Perhaps, you could use state trigger with condition on the attribute.

That worked! Final code:

trigger:
  - platform: state
    entity_id: sensor.cube_action
condition:
  condition: template
  value_template: "{{ trigger.to_state.attributes.action in ['rotate_left', 'rotate_right'] }}"

You’re welcome
