MQTT Based Smart Metering

In the concept of smart grid, the smart meter is one of the most important components. Controlling the consumption of electric power is a main aspect of smart grid technology. With the implementation of smart meters, service providers and consumers will get timely updates of the energy consumption, and this will help both the service provider and consumer control their energy consumption. This will also help in reducing irregularities during meter reading and bill generation. Consumers will have an idea of their upcoming bills as they can see their consumption details any time. It will also eliminate the need for a person to physically collect meter readings from home to home as all the readings will be available automatically on the website. In our proposed model, sensors are connected to electricity meter and to the ESP32 microcontroller. ESP32 publishes this data hourly or more frequently. This data is then subscribed by Raspberry Pi which acts as an MQTT broker here. All these consumption details along with billing details then can be seen on a website by the service provider as well as the consumer. An alert email regarding energy consumption is also sent to the consumer whenever needed.
