Abstract

An energy monitoring device (120) includes means for sensing current in a power line and generating an analog signal representative thereof. The energy monitoring device includes means for generating a digital representation of the current (220). The energy monitoring device includes means for assuming a voltage value and calculating at least one measure of power consumption using the sensed current and the assumed voltage. A method executable by said energy monitoring device is also disclosed.
