This tutorial demonstrates how to build a remote home energy monitoring system using an ESP32 microcontroller, websockets, and C++. Learn to create a solution that provides accurate, low-latency power consumption data from your smart meter, bypassing the limited information typically provided by energy suppliers. Follow along as the system is constructed to interact with a smart meter, transmit data to a custom websocket server, and display real-time information in a web browser. The complete source code is available on GitHub, making it possible to replicate this project for monitoring your own home's energy usage with precision.
