## 📡 MQTT Configuration
|
||

- **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)
|
