as domestic electrical energy consumption keeps increasing, consumers become more aware of energy usage and efficiency because of economic and environmental reasons. The energy meter described in this paper is aimed at household smart metering for better energy management. The meter system uses a single microcontroller to acquire mains voltage and current waveforms and calculate power parameters: RMS voltage and current, instant power, power factor and energy. These parameters are stored locally on memory card for long period standalone recording, or transmitted in real time using an IoT Long Range radio for instant readings or short period monitoring. Measurement data of electrical power usage of a typical family household and energy consumption is presented where domestic appliance patterns are identified over an operating period. These patterns enable the estimation of energy usage distribution among appliances.
