In order to effectively manage power demand, optimize energy usage, and integrate distributed renewable energy production, home energy management systems, or HEMSs, are essential. The primary aim is to optimize energy efficiency while maintaining customer comfort. Numerous factors, including as energy prices, meteorological conditions, load the profiles, and customer comfort levels, influence how HEMSs function. They greatly reduce the amount of power used in both personal and business smart networks as they become more and more common. This study performs a comprehensive analysis of the body of research on HEMS, including key ideas, configurations, and the supporting technologies that support their operation. Giving a thorough review of the status of HEMS innovation and its uses today is the aim. The study also discusses popular communication methods used in demand management applications and analyzes current advancements in HEMS computing. The study that follows provides readers with a comprehensive overview of current and upcoming developments in HEMS technology and solutions. Presenting a polished and original synthesis of the current material while preserving its integrity and excluding any needless elaboration is the aim.
