This study is a research aiming to build a system for smart energy metering and forecasting electricity bills. In this study, there are four main subsystems: Embedded System and Internet of Things circuit, Android application, backend application, and machine learning. This paper will explain about the subsystem of the circuit based on Embedded System and Internet of Things which is part of the smart energy metering and forecasting electricity bill system. This research is based on the importance of electricity usage in the present time due to the abundance of facilities, infrastructure, and devices that require electricity to turn on and power their components, thus the consumption of electrical energy used also becomes higher and uncontrolled. This is also reinforced by the lack of tools or systems that are able to monitor in detail about the use of this electrical energy and also the rapid development of technology so the demand for electrical energy also increases. Therefore, a smart energy metering and forecasting electricity bill system is built. This circuit based on Embedded System and Internet of Things uses several main components, such as: ESP32 DevKit V1 microcontroller as its main computing device, PZEM-004T-10A electric reading sensor to get detailed information related to electricity use on electronic devices, and relay module to regulate the electric current that enters the circuit. The end result of this subsystem is a detailed reading of electricity usage with several parameters, such as: voltage, current, power, energy, frequency, and power factor and measured in real-time in one second intervals to measure specific electronic devices. This is different from the existing energy metering that only detects total or overall energy from all uses of electrical devices within one month. Then, electricity usage can also be minimized by the existence of energy threshold in electronic devices connected with this circuit. If the electrical energy read on that day has reached or exceeded the threshold, the electric current is automatically cut off by the relay module and can only be used again the next day or when the ESP32 is reset. The conclusion obtained from the development of this system is the creation of a system capable of detecting or monitoring daily electricity usage and also saving electricity usage through the use of thresholds to prevent waste in the use of electrical energy.
