MQTT-Based Smart Home Control Dashboard using Raspberry Pi and ESP32

This project is a smart home automation dashboard developed using Raspberry Pi 5, ESP32, MQTT protocol, and Flask.
It provides a touchscreen-friendly control interface for managing multiple electrical appliances such as lights and fans through a 4-channel relay module.

The Raspberry Pi acts as the central control unit and MQTT broker, hosting a web-based dashboard that can be displayed on a 7-inch screen.
The ESP32 wirelessly communicates with the Raspberry Pi over Wi-Fi using the MQTT publish-subscribe protocol and controls the connected relays in real time.
