Overview

The Pi IoT Gateway project facilitates communication between IoT devices using a Raspberry Pi as an MQTT broker and ESP32 clients. This setup allows for efficient data collection, processing, and visualization in IoT applications.

Project Structure

This repository contains two main components:

Raspberry Pi Broker

• Folder: /dashboard
• Description: Contains the code and configuration files for setting up the Raspberry Pi as an MQTT broker and a dashboard using Python Flask and Mosquitto.

ESP32 MQTT Client

• Folder: /esp-mqtt-client
• Description: Contains the code for the ESP32 clients that connect to the Raspberry Pi broker, allowing for data publishing.

Getting Started
