This project is a mobile app Smart Home System implemented using the ESP32 microcontroller and Arduino. It allows users to remotely monitor and control appliances in a home via Wi-Fi.

• Control appliances (e.g., lights, fan, AC) using mobile
• Monitor temperature, humidity, and motion
• User authentication with persistent login
• Real-time updates using Server-Sent Events (SSE)
• Local and cloud-based control

The ESP32 communicates with the backend using:

• HTTP (REST API): for commands and status updates
• Server-Sent Events (SSE): for real-time updates to the frontend
• Wi-Fi: primary communication medium

• ESP32
• Relay Module
• DHT11 or DHT22 (Temperature & Humidity Sensor)
• PIR Motion Sensor

• Arduino IDE (ESP32 core)
• Node.js/Express backend
• Firebase Auth (with @react-native-firebase/auth)
• AsyncStorage for token persistence in Expo React Native

Implemented using Firebase Auth:

• Email/password login
• Persistent login via AsyncStorage
