SmartNest

A cross-platform mobile application for smart home automation, built with React Native and Expo. SmartNest enables users to monitor and control IoT devices remotely with secure authentication and an intuitive interface.

Features

• Device Control: Remotely manage and monitor connected IoT devices
• Firebase Integration: Real-time database synchronization and user authentication
• Secure Authentication: Email/password authentication with biometric security options
• Cross-Platform: Runs on iOS, Android, and web browsers
• Modern UI: Clean, responsive interface with native navigation
• Settings Management: Customizable app preferences and security settings

Tech Stack

• Framework: React Native with Expo (~54.0.30)
• Routing: Expo Router (~6.0.21)
• Backend: Firebase (Auth + Realtime Database/Firestore)
• Language: TypeScript
• Animations: React Native Reanimated (~4.1.1)
• Storage: AsyncStorage for local data persistence
• Security: Expo Local Authentication for biometric login

Prerequisites

• Node.js (v14 or higher)
• npm or yarn
• Expo CLI
• iOS Simulator (for macOS) or Android Emulator
• Firebase account with a configured project

Installation

1. Clone the repository

git clone https://github.com/darshan-regmi/SmartNest.git
cd SmartNest

1. Install dependencies

npm install

1. Configure Firebase

   • Create a Firebase project at Firebase Console
   • Enable Authentication (Email/Password provider)
   • Create a Firestore/Realtime Database
   • Add your Firebase config to the project (in lib/firebase.ts or similar)

2. Start the development server

npm start

Authentication Flow

SmartNest implements secure user authentication with:

• Email/password registration and login
• Firebase Authentication backend
• Optional biometric authentication (fingerprint/Face ID)
• Persistent login sessions with AsyncStorage

Configuration

Firebase Setup

Create a lib/firebase.ts file with your Firebase configuration:

import { initializeApp } from 'firebase/app';
import { getAuth } from 'firebase/auth';
import { getFirestore } from 'firebase/firestore';

const firebaseConfig = {
  apiKey: "YOUR_API_KEY",
  authDomain: "YOUR_AUTH_DOMAIN",
  projectId: "YOUR_PROJECT_ID",
  storageBucket: "YOUR_STORAGE_BUCKET",
  messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
  appId: "YOUR_APP_ID"
};

const app = initializeApp(firebaseConfig);
export const auth = getAuth(app);
export const db = getFirestore(app);

Building for Production

Android

eas build --platform android

iOS

eas build --platform ios

Web

npm run web:build

Hardware Integration

SmartNest is designed to work with ESP8266/ESP32 microcontrollers and Arduino-based IoT devices. Configure your hardware to communicate with Firebase for real-time device control.
