Energy Usage & Monitoring with Voice Controlled Home Appliances

Abstract

In the era of increasing electric rates and unattended consumption, people are facing electricity bills that are often higher than expected. Which is why we have come up with the idea of having a smart energy meter which will be plugged in your house which will show live usage after set intervals giving an idea of current usage from the consumer. Also, to be sure about all the devices whether they're on or off when we are away, we have decided to interface it with IOT enabling consumers to control their devices from everywhere in the world. We will be using Nodemcu, Relay, PZ004T and Cloud services to achieve our goal. For Smart energy meter, the Node mcu (ESP8266) It can connect to a Wi-Fi network and interact with the Internet. Relay module designed to be controlled with low voltages e.g., -3.3 V and It is connected to the ESP8266.In meter PZEM-004t Is sensor which measuring AC (RMS) voltage, current and power (single phase). energy meter which is already installed at our houses are not replaced, but a small modification on the already installed meters can change the existing meters into smart meters.
