Since the proliferation of the Internet, the development of IoT applications has now become an update for researchers. These technologies include the advancement of the internet and the use of technology to increase the usability of applications. This project provides a smart system for home energy management based on IoT, allowing remote access and control of home appliances/electronics. IoT integration switch box will play an important role in energy and water management. With the adoption of smart home devices, the Internet of Things is rapidly becoming widespread, creating a strong demand. Most smart home appliances, including smart TVs, refrigerators, smart dishwashers, air conditioners and heaters, are connected to the internet and help improve people's quality of life. The ability of smart homes to manage connections and control devices has come a long way in recent years. The system planned in this project can instantly monitor the energy used in our home and collect information including the working time and effort of each project. This project introduces a smart home energy management system that can be used to access and control all home devices from anywhere. It also controls water and electricity for smart homes. All devices connect to the main box and collect data from the Internet of Things. An application was created to monitor, track and manage energy consumption. Therefore, our main goal is to prevent energy waste caused by human negligence and provide smart energy management for home use.
