In the face of our world's growing dependence on energy, there is a critical need to enhance the efficiency of how we utilize energy resources. The most important aspect of fully utilizing something is keeping track of it. Even it is really importance but it cannot be use widely due to most of those tracking devices are expensive. Moreover, some low-cost devices are able to measure only current and voltage with poor accuracy. Due to these reasons, this paper aims to propose a smart energy monitoring device based IoT system that built from the selected low costs components and embedded with less computation burden algorithm. The monitoring device could provide real-time and detailed insights into energy consumption patterns through web and mobile application. This device empowers users by offering a clear understanding of how and when energy is being used, allowing for informed decisions on optimizing usage and reducing waste. In addition, our device also provided the physical monitoring function to ensure the convenient and reliability for our users.
