🏠 Firebase Based Smart Home Automation System

Real-Time Control Using ESP32 + Web Dashboard + Android App

By Yarana IoT Guru – Mr. Abhishek Maurya

🔥 Introduction

Aaj ke digital era me Smart Home Automation sirf luxury nahi raha — ye necessity ban chuka hai.

Is project me maine ek complete real-time Smart Home Automation System develop kiya hai jo:

• ESP32 based hai
• Firebase Realtime Database use karta hai
• Web Dashboard se control hota hai
• Android App se bhi real-time sync hota hai
• Wall Switch + Cloud dono se kaam karta hai
• Timer Automation support karta hai (IST timezone based)

Ye pura system bi-directional real-time synchronization pe kaam karta hai.

⚙️ System Architecture

Wall Switch →
→ ESP32 → Firebase Realtime DB ← Web Dashboard
Android App →

---

Working Flow:

1. Agar wall switch press hota hai
   → ESP32 relay state change karega
   → Firebase update karega
   → Web + App me instant reflect hoga
2. Agar Web se ON/OFF karoge
   → Firebase update hoga
   → ESP32 relay change karega
   → App me bhi update show hoga
3. Agar App se control karoge
   → Firebase update
   → ESP32 relay change
   → Web me reflect

🧠 Core Technologies Used

• ESP32 WiFi Microcontroller
• Firebase Realtime Database
• Firebase Authentication
• Web Dashboard (HTML + CSS + JS)
• Android App (Realtime Sync Based)
• Moment.js (Timezone Handling IST)

---

🔌 Hardware Used

• ESP32
• 4 Channel Relay Module
• Wall Switches
• WiFi Router

---

💡 Key Features of This Smart Home System

1️⃣ Real-Time Relay Control

• 4 Relays Supported
• Cloud + Local Switch Sync
• Instant feedback
• Firebase Streaming used (No delay polling)

---

2️⃣ Safe Boot Protection

System boot hote hi:

• All relays OFF state me
• Wall switch mode active
• Safe power startup

Isse power cut ke baad unsafe switching nahi hoti.

---

3️⃣ Bi-Directional Synchronization

Action Source	ESP32	Firebase	Web	App
Wall Switch	✅	✅	✅	✅
Web	✅	✅	✅	✅
Android App	✅	✅	✅	✅

Sab kuch 100% sync me.

---

4️⃣ Smart Timer System (IST Timezone)

Is system ka ek advanced feature hai:

• Relay select karo
• ON / OFF action choose karo
• Start time set karo
• Optional end time set karo
• Active days select karo (Mon-Sun)

System har 30 seconds me check karta hai aur relay ko automatic control karta hai.

Example:

• Monday se Friday
• 7:00 PM → ON
• 11:00 PM → OFF

Fully automatic.

---

5️⃣ Health Check & Auto Reconnect

ESP32:

• Firebase stream monitor karta hai
• 10 sec health check karta hai
• Disconnect hone pe auto reconnect karta hai

Highly stable architecture.

---

6️⃣ Dynamic Firebase Configuration (Web Side)

Web dashboard me:

• API Key change kar sakte ho
• Database URL change kar sakte ho
• Local storage me save hota hai
• Reload ke baad auto reconnect

Iska matlab ek hi dashboard multiple projects ke liye use kar sakte ho.

---

📱 Android App Integration

Maine isi system ka Android version bhi develop kiya hai jisme:

• Same relays show hote hain
• Real-time status update
• Timer management
• Instant feedback
• Cloud synchronized

Android app bhi same Firebase database use karta hai.

---

🌐 Web Dashboard Features

✔ Modern UI
✔ Relay ON/OFF cards
✔ Live status indicator
✔ Timer add/edit/delete
✔ Next upcoming timer display
✔ IST time display
✔ Responsive design

---

🔐 Firebase Database Structure

relays
relay1 : true/false
relay2 : true/false
relay3 : true/false
relay4 : true/false

timers
timerID
relay
action
startTime
endTime
days[]
active

Simple and scalable structure.

---

🚀 Why This System Is Powerful?

✅ No local server required
✅ No MQTT broker required
✅ Pure cloud based
✅ Real-time stream
✅ Scalable architecture
✅ Easy to expand
✅ Timer based automation
✅ Dual control (Switch + Cloud)

---
