1. An apparatus comprising:

  • at least one analog section having a current transformer having a transformer core configured to mount around an alternating current (AC) power line making it a primary winding of the current transformer, the analog section harvesting energy from a secondary winding wound around the transformer core, and storing harvested energy for use by components of the apparatus, the analog section providing an analog signal responsive to AC in the power line and a pulse having a frequency responsive to the alternating current in the AC power line;

    a microcontroller coupled to the at least one analog section to receive energy for the operation of at least the microcontroller, and to receive the analog signal and the pulses;

    a memory coupled to the microcontroller; and

    a transmitter coupled to the microcontroller to transmit, under the control of the microcontroller, information responsive to at least one of the analog signal and the pulses as an indication of the power consumption of a load connected to the power line.
