Automatic and Smart homes (ASHs) is one of the most important part of smart grid (SG) terminal. Demand-Side Energy Management System (DSEMS) aims to provide direct energy feedback whilst (or shortly after) consumption occurs, so as to persuade users to achieve energy saving and efficiency. However, existing solutions are challenged by the lack of fully considering the actual situation of fiber to the house (FTTH) based communication of state power construction and related study on users' behaviors and preferences in China. A novel mode for design and development of demand side energy management ASHs system in SGT is described in this paper. The design of ASHs system is closely linked with FTTH power construction in China, which not only can improve the intelligence of electricity, but also achieve interaction between enterprises and electricity user-way, and is conducive to the distribution network safe, reliable and economic operation. This system is suitable for educational purposes in terms of understanding the what-if and how of DSEMS based on FTTH.
