Outdoor Plug Notifications of power change

I would like to get notifications when a device powered on by the outdoor plug stops consuming electricity. I have a fan running in a pool pump house which must run all the time to vent chemical gasses. I need a way to know if the fan fails. or the circuit looses power. I would suggest the following notifications:

  • Socket on and device current changed to 0 (Consuming device has failed / turned off)
  • Socket on and device current changed from 0 (Consuming device has turned on)
    Perhaps these can be consolidated into some sort of range instead of just 0, but I am mostly concerned about 0.
  • Outdoor Plug Power up (Used to denote return from power outage)
