## 🔌 WebSocket Real-Time Broadcasting

Setiap GET request ke endpoint akan automatically memicu broadcast event ke WebSocket channel yang sesuai.

### Subscribe to Channel (JavaScript)
```javascript
import Echo from 'laravel-echo';

// Listen to suhu updates
Echo.channel('monitoring.suhu')
    .listen('suhu.updated', (event) => {
        console.log('Temperature updated:', event.value);
    });

// Listen to multiple channels
Echo.channel('listrik.voltage.l1l2')
    .listen('voltage_l1l2.updated', (event) => {
        console.log('Voltage L1-L2:', event.value);
    });

echo.channel('daya.active.r')
    .listen('active_power_r.updated', (event) => {
        console.log('Active Power R:', event.value);
    });
```

### Broadcast Event Structure
```json
{
  "event": "suhu.updated",
  "channel": "monitoring.suhu",
  "data": { "value": 25.5 }
}
```

---

## 📱 cURL Examples

### Get Latest Suhu

curl -X GET "http://localhost:8000/api/monitoring/suhu"
```

### Get All Monitoring Data
```bash
curl -X GET "http://localhost:8000/api/monitoring/all"
```

### Get Listrik History

## 🎨 Frontend Integration Example

### Vue.js Component
```vue
<template>
  <div class="monitoring-dashboard">
    <div class="sensor-card">
      <h3>Temperature</h3>
      <p class="value">{{ suhu }}°C</p>
      <time>{{ timestamp }}</time>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      suhu: null,
      timestamp: null
    }
  },
  mounted() {
    // Subscribe to real-time updates
    Echo.channel('monitoring.suhu')
      .listen('suhu.updated', (event) => {
        this.suhu = event.value;
        this.timestamp = new Date().toLocaleTimeString();
      });
    
    // Also fetch initial data
    this.getSuhuData();
  },
  methods: {
    async getSuhuData() {
      const response = await fetch('/api/monitoring/suhu');
      const data = await response.json();
      this.suhu = data.value;
      this.timestamp = data.timestamp;
    }
  }
}
</script>
```

### React Hook
```jsx
import { useEffect, useState } from 'react';

function TemperatureMonitor() {
  const [temperature, setTemperature] = useState(null);
  const [timestamp, setTimestamp] = useState(null);

  useEffect(() => {
    // Fetch initial data
    fetch('/api/monitoring/suhu')
      .then(res => res.json())
      .then(data => {
        setTemperature(data.value);
        setTimestamp(data.timestamp);
      });

    // Subscribe to real-time updates
    window.Echo.channel('monitoring.suhu')
      .listen('suhu.updated', (event) => {
        setTemperature(event.value);
        setTimestamp(new Date().toLocaleTimeString());
      });
  }, []);

  return (
    <div>
      <h3>Temperature: {temperature}°C</h3>
      <p>Last Updated: {timestamp}</p>
    </div>
  );
}

export default TemperatureMonitor;
```

## 🔒 Authentication & Rate Limiting

Saat ini semua endpoints adalah **PUBLIC**. Untuk production, tambahkan:

### Middleware Authentication
```php
Route::middleware(['auth:sanctum'])->group(function () {
    Route::prefix('monitoring')->group(function () {
        // Protected endpoints
    });
});
```

### Rate Limiting
```php
Route::middleware(['throttle:60,1'])->group(function () {
    // Rate limited to 60 requests per minute
});
```

## 📊 Data Units Reference

| Sensor | Unit | Range | Keterangan |
|--------|------|-------|------------|
| Suhu (Temperature) | °C | -40 to 125 | Celcius |
| Kelembapan (Humidity) | % | 0-100 | Relative Humidity |
| PM2.5 | µg/m³ | 0-500+ | Micro grams per cubic meter |
| PM10 | µg/m³ | 0-500+ | Micro grams per cubic meter |
| eCO2 | ppm | 400-8000+ | Parts per million |
| TVOC | ppb | 0-65000+ | Parts per billion |
| Voltage | V | 0-440 | Volt |
| Current | A | 0-100+ | Ampere |
| Frequency | Hz | 45-65 | Hertz (50Hz standard) |
| Power Factor | (none) | 0-1 | Real number 0 to 1 |
| Power | W/VAR/VA | 0-100000+ | Watt/VAR/Volt-Ampere |

## 🚀 Performance Tips

### 1. Use `/all` endpoints untuk get semua data sekaligus
```bash
GET /api/monitoring/all     # Better than 7 separate requests
GET /api/listrik/all        # Better than 12 separate requests
GET /api/daya/all           # Better than 9 separate requests
```

### 2. Subscribe WebSocket channels once
```javascript
// ✅ Good - Subscribe once per channel
Echo.channel('monitoring.suhu').listen('suhu.updated', handleUpdate);

// ❌ Bad - Don't subscribe multiple times
for(let i = 0; i < 10; i++) {
  Echo.channel('monitoring.suhu').listen('suhu.updated', handleUpdate);
}
```

### 3. Use `/history` untuk data historical analysis
```bash
GET /api/monitoring/history  # Last 100 records
```

### 4. Throttle API polling
```javascript
// Poll every 5 seconds
setInterval(() => {
  fetch('/api/monitoring/suhu').then(/* ... */);
}, 5000);

// Better: Use WebSocket (realtime, no polling needed)
Echo.channel('monitoring.suhu').listen('suhu.updated', (event) => {
  console.log('Real-time update:', event.value);
});
```
