Template Motion Sensor from Power

I am trying to create a template binary sensor to use as a motion sensor from an external motion flood light that I monitor its power consumption. Currently I have:

platform: template
      friendly_name: "East Motion Light Status"
      device_class: power
      value_template: "{{ states('sensor.lc03b4_power')|float > 2.0 }}"

It returns unavailable. The light shows as drawing 30 watts when triggered. Any help would be appreciated. Thanks.
