SmartMeter.KOM: A Low-Cost Wireless Sensor for Distributed Power Metering
Most current smart metering solutions aim at increasing user awareness for their household's electrical energy consumption. Although some smart meters make use of wireless data transfers between their sensor and display units, their integration into existing wireless sensor networks is hampered by proprietary communication interfaces and their lack of re-programmability. Furthermore, the sole availability of aggregate consumption values renders current meters insufficient for novel application scenarios like smart home automation, for which information at device-level granularity and high resolution is vital. The authors address these shortcomings of existing solutions by presenting SmartMeter.KOM, their wireless sensor node capable of determining the current consumption of individual electrical appliances at high resolution.
