# RF Protocol Database

**The largest open-source unified Sub-GHz RF device protocol database.**

425 device signatures across 40 categories, merged from 4 authoritative sources. Covers the 300-928 MHz ISM spectrum -- every garage door opener, weather station, car key fob, TPMS sensor, security alarm, smart meter, and IoT device that transmits below WiFi frequencies.

## Stats

| Metric | Count |
|--------|-------|
| **Total Protocols** | 425 |
| **Categories** | 40 |
| **Sources** | 4 |
| **Modulation Types** | OOK, FSK, ASK, Manchester, DMC |
| **Frequency Bands** | 315, 345, 433, 868, 915 MHz ISM |

## Files

|------|--------|-------------|
| `rf_protocols.json` | JSON | Full database with all fields |
| `rf_protocols.csv` | CSV | Flat export for spreadsheets and SQL import |
| `build.py` | Python | Build script to regenerate from upstream sources |

## Categories

| Category | Count |
|----------|-------|
| Other Sensors & Devices | 89 |
| Temperature & Humidity Sensors | 72 |
| Weather Stations & Sensors | 51 |
| TPMS (Tire Pressure) | 28 |
| Energy & Water Meters | 26 |

}
```

## CSV Schema

```
name,category,manufacturer,modulation,encoding,frequency,short_width,long_width,bits,checksum,source,device_id
```

## Usage

### Python
```python
import json

with open('rf_protocols.json') as f:
    db = json.load(f)

# Search by category
weather = [d for d in db['devices'] if 'Weather' in d.get('category', '')]
print(f"{len(weather)} weather protocols")

# Search by manufacturer
acurite = [d for d in db['devices'] if d.get('manufacturer') == 'Acurite']
print(f"{len(acurite)} Acurite devices")

# Search by modulation
ook = [d for d in db['devices'] if d.get('modulation') == 'OOK']
print(f"{len(ook)} OOK-modulated devices")
```

### JavaScript
```javascript
const db = await fetch('rf_protocols.json').then(r => r.json());

// Filter by frequency band
const ism433 = db.devices.filter(d => d.frequency && d.frequency > 433e6 && d.frequency < 434e6);
```

### SQL Import
```sql
CREATE TABLE rf_protocols (
    name TEXT, category TEXT, manufacturer TEXT,
    modulation TEXT, encoding TEXT, frequency BIGINT,
    short_width INT, long_width INT, bits TEXT,
    checksum TEXT, source TEXT, device_id TEXT
);

\copy rf_protocols FROM 'rf_protocols.csv' CSV HEADER;
```

## Rebuilding

To regenerate the database from upstream sources:

```bash
# Clone upstream repos into sibling directories
git clone https://github.com/merbanan/rtl_433.git
git clone https://github.com/PentHertz/urh-ng.git
git clone https://github.com/Zero-Sploit/FlipperZero-Subghz-DB.git

# Run build script
python3 build.py
```
