|
|
|
## 🚀 Fitur Baru
|
|
|
|
### 1. Railway Worker (24/7 Backend)
|
|
**Teknologi:**
|
|
- Node.js 18+
|
|
- Firebase Admin SDK
|
|
- BullMQ (job queue)
|
|
- Redis (in-memory DB)
|
|
- Cron (scheduled tasks)
|
|
|
|
**Kemampuan:**
|
|
- ✅ Waktu Mode - Schedule penyiraman by time
|
|
- ✅ Sensor Mode - Auto watering by threshold
|
|
- ✅ Auto History Logging - Every 10 minutes
|
|
- ✅ Auto Cleanup - Daily at 2 AM (retain 30 days)
|
|
- ✅ Health Monitoring - Every 5 minutes
|
|
- ✅ Graceful Shutdown - Clean resource cleanup
|
|
- ✅ Error Recovery - Auto-retry & safety turn-off
|
|
|
|
**Keuntungan:**
|
|
- 🌟 Berjalan 24/7 meskipun HP mati
|
|
- 🌟 Reliable (Railway auto-restart jika crash)
|
|
- 🌟 Scalable (bisa handle multiple users/devices)
|
|
- 🌟 Cost-effective ($3-5/month, free tier available)
|
|
- 🌟 Production-grade architecture
|
|
|
|
### 2. Connection Monitoring
|
|
**Features:**
|
|
- Real-time Firebase connection status
|
|
- Stream untuk listen connection changes
|
|
- Wait-for-connection utility
|
|
- Callbacks untuk custom handling
|
|
|
|
**Usage:**
|
|
```dart
|
|
final monitor = ConnectionMonitorService();
|
|
monitor.start();
|
|
|
|
if (monitor.isConnected) {
|
|
// Safe to proceed with Firebase operations
|
|
}
|
|
|
|
monitor.connectionStream.listen((connected) {
|
|
print(connected ? 'Connected' : 'Disconnected');
|
|
});
|
|
```
|
|
|
|
### 3. Automation Constants
|
|
**Features:**
|
|
- Centralized configuration values
|
|
- Validation helpers
|
|
- Self-documenting code
|
|
- Easy maintenance
|
|
|
|
**Examples:**
|
|
```dart
|
|
AutomationConstants.defaultDurasiDetik // 60
|
|
AutomationConstants.wateringCooldownSeconds // 120
|
|
AutomationConstants.totalPots // 5
|
|
AutomationConstants.isValidDurasi(30) // true
|
|
```

## 🏗️ Arsitektur Sistem
|
|
|
|
### Old Architecture (Flutter Only)
|
|
```
|
|
┌─────────────┐
|
|
│ Flutter App │ ← Timer/Stream (hanya saat app buka)
|
|
└──────┬──────┘
|
|
↓
|
|
┌──────────────┐
|
|
│ Firebase RTDB│
|
|
└──────┬───────┘
|
|
↓
|
|
┌──────────────┐
|
|
│ ESP32/Sensor │
|
|
└──────────────┘
|
|
|
|
❌ Problem: App tertutup = automation stop
|
|
```
|
|
|
|
### New Architecture (Production)
|
|
```
|
|
┌─────────────┐
|
|
│ Flutter App │ ← UI & Manual Control
|
|
└──────┬──────┘
|
|
↓
|
|
┌──────────────────────────────────┐
|
|
│ Firebase Realtime DB │ ← Central Data Hub
|
|
└─────────┬────────────────────────┘
|
|
↓ ↓
|
|
┌─────────────────┐ ┌──────────────┐
|
|
│ Railway Worker │ │ ESP32/Sensor │
|
|
│ (24/7 Cloud) │ └──────────────┘
|
|
│ │
|
|
│ • Scheduler │
|
|
│ • Automation │
|
|
│ • History Log │
|
|
│ │
|
|
│ ↓ Redis Queue│
|
|
└─────────────────┘
|
|
|
|
✅ Solution: Worker always running, independent dari app
|
|
```
|

## 🔧 Maintenance Guide
|
|
|
|
### Daily

|
|
- ✅ Auto: History logging (every 10 min)
|
|
|
|
### Weekly
|
|

|
|
|
|
### Monthly
|
|

|
|
|
|
## ⚠️ Known Limitations & TODOs
|
|
|
|
### Current Limitations
|
|
1. Worker timezone = UTC (need to convert dari local time)
|
|
2. Flutter app masih punya local automation (should disable di production)
|
|
3. No push notifications untuk alerts (future enhancement)
|
|
|
|
### TODO (Nice to Have)
|
|
- [ ] Disable local automation di production build
|
|
- [ ] Add UI indicator "Server automation active"
|
|
- [ ] Push notifications untuk alerts (FCM)
|
|
- [ ] Unit tests untuk automation logic
|
|
- [ ] Integration tests end-to-end
|
|
- [ ] Replace WillPopScope dengan PopScope
|
|
- [ ] Input validation di UI forms
|
|
- [ ] Error reporting (Sentry/Crashlytics)
|
