In today's reality, Automatic frameworks are being favored over manual frameworks. The quick increment in the number of clients of the web over the previous decade has made the Internet an integral part of life, and IoT is the most recent and rising web innovation. Electricity is one of the fundamental necessities of human beings, it is commonly used for domestic, industrial, and agricultural purposes. These days, power theft is the main issue, costing electricity boards a lot of money and creating payment issues for customers. In our country, these situations are more often. If these thefts are prevented then a lot of power can be saved. This is done using a Smart EB meter. An energy meter chip is used in SEMs to measure the amount of electric energy used, and wireless protocols are used for data transmission. This project presents an EB meter box via automatic billing system by display. electricity continues to rise, the existing grid faces challenges related to aging infrastructure, poor visibility, and mechanical switches. Additionally, greenhouse gas emissions from the electricity industry and other stressors necessitate grid modernization. The proposed smart energy meter leverages Internet of Things (IoT) technology, enabling two-way data communication over LPWAN (Low Power Wide Area Network). These are this system's salient characteristics. The meter incorporates theft and tamper detection capabilities. Users receive notifications in case of any unauthorized interference. Key Words: Internet of Things (IoT), Light-dependent resistor (LDR), ESP8266 Microcontroller (NodeMCU), Liquid-crystal display, LoRaWAN, Energy Meter.
