Recent advances in the Internet of Things (IoT) and cloud computing have led to the development of various smart home applications and services. In addition, with the increase in the number of home appliances, the daily electricity consumption is also increasing, which increases the need for smart energy meters and monitoring systems. The proposed smart energy meter system measures current and voltage, calculates energy consumption and other information. The system is realized using ESP32s board (combination of microcontroller and Wi-Fi module), which connects to the internet and uploads data to the cloud. ThingSpeak is used as a cloud web server, which allows any user to remotely view individual consumption figures. This paper presents the design and implementation of a household smart energy meter that can collect and store energy consumption data of household appliances and major loads. The system measures three-phase currents and voltages, calculates power consumption, transmits the data to the cloud and displays it on an OLED screen.
