Help automating a switch to trigger a scene!

Complete newbie here. Trying to get automations to work with a xiaomi wall switch to trigger a philips hue scene

Have codes setup here, but clicking trigger to test the scene don’t seem to do anything. I’d assume my trigger codes are wrong. Have also tried to switch the codes around where when scene is triggered, wall switch turns on. But no luck on that one either. So far I’ve only been successful in executing automations when its connected to a boolean trigger. Help is appreciated.

- action:
  - data:
      entityid: script.bedroom_reading
      service: script.turn_on
      alias: Reading auto test
  condition: []
     id: '1509307819703'
  trigger:
  - event_data:
      entity_id: switch.wall_switch_left
      state: 'on'
    event_type: button_pressed
    platform: event

I use a template that follows this sort of format for this very use:

- alias: INSERT_ALIAS
  trigger:
    platform: event
    event_type: INSERT_TYPE
    event_data:
      entity_id: INSERT_TRIGGER_ENTITY
      click_type: INSERT_TYPE
  action:
  - service: INSERT_SERVICE
    data:
      entity_id: INSERT_TARGET_ENTITY

So a real life example where I use a Xiaomi two gang wireless wall switch to turn off a Hue bulb.

- alias: Bedtime
  trigger:
    platform: event
    event_type: click
    event_data:
      entity_id: binary_sensor.wall_switch_right_XXXXXXXXXXXXe
      click_type: single
  action:
  - service: light.turn_off
    data:
      entity_id: light.Bedroom_Light

Let me know if this helps or you get stuck!
