Wemo Automation based on current power

Was trying to do some very basic automation, like turning off the AV system based on the wattage of wemo (wife usually forgets to turn the setup properly off, that’s 120W total sucked out when on standby). Found some help but still it doesn’t seem to turn off anything. Logs didn’t have any errors either. Anyways, here’s my config:

cat automations.yaml
- action:
  - data:
      entity_id: switch.av_front
    service: switch.turn_off
  - data:
      entity_id: switch.av_back
    service: switch.turn_off
  alias: Turn off idle AV
  condition: []
  id: '1507015859391'
  trigger:
  - below: '80'
    entity_id: switch.av_front
    platform: numeric_state
    value_template: '{% if states.switch.av_front %}{{ states.switch.av_front.attributes.current_power_w
      }}{% else %}Off{% endif %}'
