Simple question about trigger and numeric_state

So i have the below code but it never triggers. What am i missing? The action is working fine and the lux sensor is reporting.

alias: Living room lights off with lux
description: ''
trigger:
  - platform: numeric_state
    entity_id: sensor.philips_sml001_0745b504_illuminance
    above: '50'
condition: []
action:
  - service: light.turn_off
    target:
      entity_id: light.living_room_lights
mode: single

That trigger will only trigger when the state rises past 50. It will not trigger again until it lowers below 50 and rises above again. It does not trigger when you’re already above 50 and move further above 50.

If you want it to continuously trigger, change to a state trigger and use a numerical condition.
