## 📡 MQTT Configuration

### Backend (Railway):
- **MQTT Broker:** ❌ Disabled (Railway tidak support custom ports)
- **WebSocket MQTT:** ❌ Disabled

### External MQTT Broker (HiveMQ):
- **Host:** `broker.hivemq.com`
- **Port:** `1883` (TCP) atau `8883` (WebSocket)
- **Topics:**
  - `novil/pengering/data` - Data sensor dari ESP32
  - `novil/pengering/status` - Status messages
  - `novil/pengering/button` - Button events
  - `novil/pengering/control` - Control commands

## 🚀 Next Steps

### 1. Test dengan ESP32

**Update ESP32 Code:**
```cpp
const char* mqtt_server = "broker.hivemq.com";  // Public MQTT broker
```

**Upload ke ESP32 dan test:**
- ESP32 connect ke WiFi
- ESP32 connect ke HiveMQ
- ESP32 publish data ke `novil/pengering/data`
- Backend terima dan simpan ke database

### 2. Test dengan Flutter App

**Update Flutter Code:**
```dart
// MQTT Service
final mqttService = MqttService();
await mqttService.connectWithRetry(); // Connect ke HiveMQ

// API Service
final apiService = ApiService();
final data = await apiService.getLatestData(); // Get dari Railway
```

**Test:**
- Flutter connect ke HiveMQ (real-time data)
- Flutter call Railway API (control & history)
- Send command START/RESET
- Manual control relay

### 3. Initialize Database Tables

Jika belum ada data, initialize tables:
```powershell
Invoke-WebRequest -Uri "https://web-production-47eb.up.railway.app/api/database/init" -Method POST -UseBasicParsing
```

---

## 📝 Environment Variables (Railway)

```bash
# Database (Auto-set by Railway MySQL Plugin)
MYSQL_URL=mysql://root:...@mysql.railway.internal:3306/railway
MYSQLHOST=mysql.railway.internal
MYSQLPORT=3306
MYSQLUSER=root
MYSQLPASSWORD=...
MYSQLDATABASE=railway

# Server
NODE_ENV=production
PORT=8080  # Auto-set by Railway

# MQTT (Optional, default: disabled)
ENABLE_MQTT_BROKER=false  # Tidak perlu set, default disabled
```

---

## 🧪 Test Commands

### PowerShell:

```powershell
# Health check
Invoke-WebRequest -Uri "https://web-production-47eb.up.railway.app/" -UseBasicParsing

# Test database
Invoke-WebRequest -Uri "https://web-production-47eb.up.railway.app/api/database/test" -UseBasicParsing

# Get latest data
Invoke-WebRequest -Uri "https://web-production-47eb.up.railway.app/api/data/latest" -UseBasicParsing

# Send command START
Invoke-WebRequest -Uri "https://web-production-47eb.up.railway.app/api/control" -Method POST -Body '{"command":"START"}' -ContentType "application/json" -UseBasicParsing

# Get statistics
Invoke-WebRequest -Uri "https://web-production-47eb.up.railway.app/api/stats" -UseBasicParsing
```

### Browser:
