IOT Based Smart Real Time Energy Monitoring & Device Control Using Modbus, Node-Red, Thingspeak

Today, saving electricity is very important for homes and industries. This project helps in smart energy management using low-cost and easy tools. It uses the ESP8266 Wi-Fi module to read energy usage in real-time. The system uses MODBUS protocol to collect data from the energy meter. ESP8266 sends this data to Node-RED, which shows it in a user-friendly way. Users can see energy usage through graphs and dashboards. If the electricity usage goes too high, the system can turn off some devices automatically. This helps in saving power and reducing electricity bills. The data is also sent to ThingSpeak, a cloud platform for storing and analyzing data. Users can check their energy use anytime from their mobile or laptop. They can also download the data in Excel format for reports. The system helps to find patterns and detect any problems. It supports smart decision-making for energy saving. This project is low-cost, easy to use, and useful for both small and large setups. It promotes green energy habits and better control over electricity usage.
