Abstract
A sub-meter device for use in a home energy management (HEM) network. The sub-meter device measure power characteristics related to usage of an appliance (or other device) within a HEM network and provides such data to a home energy controller or the like. The sub-meter device can include one or more sensors, such as a current transformer, Rogowski coil, shunt resistor, or hall effect sensor, for collecting data relating to at least one of real power consumption, reactive power consumption, line frequency, line voltage, power factor, leading/lagging voltage-current comparison, and apparent power, etc.
