Smart Saver: A Consumer-Oriented Web Service for Energy Disaggregation

Energy disaggregation, which aims to break down the total energy consumption of household into that of individual appliances, plays an important role in energy conservation and has caught more and more attention. Realizing that current energy disaggregation approaches are hard to perform for the ordinary consumers and free and open applications/services are not generally available, we provide a consumer-oriented web service, Smart Saver, which is not only open and free to the consumers but also user-friendly and easy-to-use for energy disaggregation. Based on a simple power model, a sparse switching event recovery model is established as the core of Smart Saver. By feeding the basic power information of appliances into Smart Saver, the users will be provided with 1) online energy disaggregation and appliance monitoring if they have smart meters communicating with our service, or 2) offline energy disaggregation if they upload their aggregated power data.
