  Smart energy management based on the Internet of Things (IoT) aims to achieve
optimal energy utilization through real-time energy monitoring and analyses of
power consumption patterns in IoT networks (e.g., residential homes and
offices) supported by wireless technologies. This is of great significance for
the sustainable development of energy. Energy disaggregation is an important
technology to realize smart energy management, as it can determine the power
consumption of each appliance from the total load (e.g., aggregated data).
Also, it gives us clear insights into users' daily power-consumption-related
behaviours, which can enhance their awareness of power-saving and lead them to
a more sustainable lifestyle. This paper reviews the state-of-the-art
algorithms for energy disaggregation and public datasets of power consumption.
Also, potential use cases for smart energy management based on IoT networks are
presented along with a discussion of open issues for future study.
