Smart Home with Energy Saving Using Demand Side Management Through Particle Swarm Optimization and Home Assistant

Smart home is part of Internet of Things which makes human life easier. However, obstacles arise because each smart home brand has a different control application, so to use a different brand, the respective application must be installed. Another problem is the limited electric power for each house, so it is necessary to arrange so that all electrical equipment only turns on when needed by setting priorities and interests. The contribution of this research is the incorporation of Demand Side Management with PSO to save energy and the Home Assistant Framework to connect smart devices from various brands such as Millenix, Sonoff, Bardi, Ezviz, with additional algorithms to prevent trip down. The test results show that the application made can be used for all new smart device brands added and is able to turn off smart devices according to the results of the PSO algorithm by including the decisions of the users. In addition, after the PSO algorithm was tested and implemented, a 14% percentage reduction in electrical energy use (kWh) was obtained.
