Home-Fi: Smart Home Automation System

A modern home automation solution combining Flutter's beautiful UI with ESP32's powerful capabilities and Adafruit IO's reliable cloud infrastructure.

✨ Features

• 🏠 Control multiple home appliances remotely
• 💡 RGB light control with color picker
• 📊 Real-time device status monitoring
• 🌡️ Temperature and humidity sensing
• 🔐 Secure communication with Adafruit IO
• 📱 Beautiful, responsive Flutter UI
• ⚡ Low-latency ESP32 control

🎯 System Architecture

Mobile App (Flutter) <-> Adafruit IO Cloud <-> ESP32 Device <-> Home Appliances

• Flutter App: Handles user interface and cloud communication
• Adafruit IO: Manages device state and real-time data
• ESP32: Controls physical devices and sensors

🚀 Getting Started

Prerequisites

• Flutter SDK (2.0 or higher)
• Arduino IDE
• ESP32 Development Board
• Adafruit IO Account
• Basic electronic components (relays, RGB LED, sensors)

Installation

1. Clone the repository

   git clone https://github.com/yourusername/home-fi.git
   cd home-fi

2. Set up Flutter app

   flutter pub get

3. Configure Adafruit IO

   • Create an Adafruit IO account
   • Set up required feeds (switches, RGB values, sensor data)
   • Copy your AIO Key

4. ESP32 Setup

   • Install required libraries in Arduino IDE
   • Update credentials in ESP32 code

   #define IO_USERNAME  "your_username"
   #define IO_KEY       "your_aio_key"

5. Run the app

   flutter run

📱 User Interface

🛠️ Hardware Setup

Components Required

• ESP32 Development Board
• Relay Module (for appliance control)
• RGB LED Strip
• DHT11/DHT22 Sensor (optional)
• Power Supply
• Connecting Wires

📡 Communication Protocol

The system uses MQTT protocol for communication:

• Topics: Organized by device type (switches/rgb/sensors)
• Message Format: JSON payloads for complex data
• Update Frequency: Real-time for switches, 1s for sensor data
