This study aims to design and implement a three-phase electrical energy monitoring system based on the Internet of Things (IoT) using the ESP32 microcontroller as the core of the system. The system is designed to read electrical parameters in real-time, including frequency, power factor, phase-to-neutral voltage, phase currents, active power, and total energy. These parameters are then transmitted to the Blynk.cloud platform for visualization through both mobile applications and a web dashboard. The method used in this research involves connecting the ESP32 device to a Schneider METSEPM2120 power meter using the Modbus RTU protocol over an RS485 network. The collected data shows that the system frequency remains within the range of 49.96 to 50.03 Hz, with an average power factor above 0.93. Voltage and current measurements for each phase are stable, with no significant imbalance detected, while active power readings ranged between 7.9 – 8.2 kWh.
