||||
|
||||
### Success Response
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"data": { ... },
|
||||
"message": "Optional success message"
|
||||
}
|
||||
```
|
||||
|
||||
### Error Response
|
||||
```json
|
||||
{
|
||||
"success": false,
|
||||
"error": "Error description",
|
||||

|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Rate Limiting
|
||||
|
||||
Currently no rate limiting is implemented.
|
||||
|
||||
**Recommended limits for production:**
|
||||
- `/api/rtl433/status` - 60 requests/minute
|
||||
- `/api/rtl433/protocols` - 10 requests/minute
|
||||
- `/api/v1/captures/upload` - 100 uploads/hour
|
||||
|
||||
---
|
||||
|
||||
## Common Use Cases
|
||||
|
||||
### 1. Check if RTL_433 is Available Before Upload
|
||||
|
||||
```javascript
|
||||
async function uploadWithRTL433() {
|
||||
// Check RTL_433 status first
|
||||
const status = await fetch('/api/rtl433/status').then(r => r.json());
|
||||
|
||||
if (!status.available) {
|
||||
console.warn('RTL_433 not available, falling back to signature matching');
|
||||
}
|
||||
|
||||
// Proceed with upload
|
||||
const formData = new FormData();
|
||||
formData.append('files', file);
|
||||
formData.append('manifest', JSON.stringify(manifest));
|
||||
|
||||
const result = await fetch('/api/v1/captures/upload', {
|
||||
method: 'POST',
|
||||
body: formData
|
||||
}).then(r => r.json());
|
||||
|
||||
return result;
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Display RTL_433 Protocols in UI
|
||||
|
||||
```javascript
|
||||
async function loadProtocols() {
|
||||
const data = await fetch('/api/rtl433/protocols').then(r => r.json());
|
||||
|
||||
const select = document.getElementById('protocol-select');
|
||||
data.protocols.forEach(protocol => {
|
||||
const option = document.createElement('option');
|
||||
option.value = protocol.id;
|
||||
option.textContent = `[${protocol.id}] ${protocol.name}`;
|
||||
select.appendChild(option);
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Show RTL_433 Results in Capture Details
|
||||
|
||||
```javascript
|
||||
function displayCapture(capture) {
|
||||
const container = document.getElementById('capture-details');
|
||||
|
||||
// Show RTL_433 decoded devices
|
||||
if (capture.rtl433_decoded && capture.rtl433_decoded.length > 0) {
|
||||
const rtlSection = document.createElement('div');
|
||||
rtlSection.className = 'rtl433-results';
|
||||
rtlSection.innerHTML = `
|
||||
<h3>RTL_433 Decoded (High Confidence)</h3>
|
||||
${capture.rtl433_decoded.map(d => `
|
||||
<div class="device">
|
||||
<strong>${d.manufacturer} ${d.model}</strong>
|
||||
<span class="confidence">${(d.confidence * 100).toFixed(0)}%</span>
|
||||
<span class="protocol">Protocol ${d.protocol_id}</span>
|
||||
</div>
|
||||
`).join('')}
|
||||
`;
|
||||
container.appendChild(rtlSection);
|
||||
}
|
||||
|
||||
// Show all matches
|
||||
if (capture.matched_devices && capture.matched_devices.length > 0) {
|
||||
const matchSection = document.createElement('div');
|
||||
matchSection.innerHTML = `
|
||||
<h3>All Matches</h3>
|
||||
${capture.matched_devices.map(m => `
|
||||
<div class="match">
|
||||
<span>${m.device_name}</span>
|
||||
<span class="method">${m.method}</span>
|
||||
<span class="confidence">${(m.confidence * 100).toFixed(0)}%</span>
|
||||
</div>
|
||||
`).join('')}
|
||||
`;
|
||||
container.appendChild(matchSection);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### RTL_433 Status Returns "unavailable"
|
||||
|
||||
**Problem:** `/api/rtl433/status` shows `"available": false`
|
||||
|
||||
**Solutions:**
|
||||
1. Install RTL_433:
|
||||
```bash
|
||||
sudo apt-get install rtl-433
|
||||
```
|
||||
|
||||
2. Verify installation:
|
||||
```bash
|
||||
rtl_433 -V
|
||||
```
|
||||
|
||||
3. Check PATH:
|
||||
```bash
|
||||
which rtl_433
|
||||
```
|
||||
|
||||
### Protocols Endpoint Returns Empty
|
||||
|
||||
**Problem:** `/api/rtl433/protocols` returns `"total": 0`
|
||||
|
||||
**Cause:** RTL_433 binary not accessible
|
||||
|
||||
**Solution:** Restart API server after installing RTL_433
|
||||
|
||||
### Upload Returns No RTL_433 Decodes
|
||||
|
||||
**Problem:** `rtl433_decoded` is always empty
|
||||
|
||||
**Possible Causes:**
|
||||
1. Signal too short/noisy for RTL_433
|
||||
2. Protocol not supported
|
||||
3. RAW data missing from .sub file
|
||||
|
||||
**Check:**
|
||||
- Verify .sub file has `RAW_Data` field
|
||||
- Try with known working captures (weather sensors)
|
||||
- Check decoder logs for errors
|
||||
|
||||
---
|
||||
|
||||
## Performance Notes
|
||||
|
||||
### RTL_433 Decode Time
|
||||
- Average: 0.01-0.05 seconds per file
|
||||
- Timeout: 10 seconds
|
||||
- Subprocess overhead: ~10-50ms
|
||||
|
||||
### Caching (Future)
|
||||
Phase 7 will add caching to reduce repeated decodes:
|
||||
- Cache key: SHA256 of RAW_Data
|
||||
- TTL: 15 minutes
|
||||
- Expected speedup: 90%+ for duplicates
|
||||
|
||||
---
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### Input Validation
|
||||
- File size limits: 1MB per .sub file
|
||||
- File type validation: Must be valid .sub format
|
||||
- GPS coordinate validation: -90 to 90 lat, -180 to 180 lon
|
||||
|
||||
### Subprocess Safety
|
||||
- RTL_433 runs in isolated subprocess
|
||||
- 10 second timeout prevents hangs
|
||||
- Temp files cleaned up automatically
|
||||
- No user input passed to shell
|
||||
|
||||
### Rate Limiting (TODO)
|
||||
Production deployment should implement:
|
||||
- Per-IP rate limiting
|
||||
- API key authentication
|
||||
- Upload quotas
|
||||
|

|
||||
|
||||
## Completed Phases
|
||||
|
||||
### ✅ Phase 1: Installation (30 min)
|
||||
**Status:** Complete
|
||||
|
||||
```bash
|
||||
$ rtl_433 -V
|
||||
rtl_433 version 23.11 (2023-11-28) inputs file rtl_tcp RTL-SDR SoapySDR
|

||||
- RTL_433 uses `am.s16` format (16-bit signed little-endian integers)
|
||||
- Direct 1:1 mapping from Flipper RAW_Data
|
||||
- Positive values = HIGH pulse duration (μs)
|
||||
- Negative values = LOW pulse duration (μs)
|
||||
|
||||
**File:** `src/parser/rtl433_converter.py`
|
||||
|
||||
### ✅ Phase 3: Converter Implementation (2-3 hours)

|
||||
|
||||
```python
|
||||
from src.parser.rtl433_converter import get_converter
|
||||
from src.parser.sub_parser import parse_sub_file
|
||||
|
||||
converter = get_converter()
|
||||
metadata = parse_sub_file('capture.sub')
|
||||
pulse_file = converter.convert_metadata(metadata)
|
||||
# Result: /tmp/giglez_rtl433/pulse_433.920MHz.am.s16
|
||||
```
|
||||
|

|
||||
|
||||
## Known Limitations
|
||||
|
||||
### Test Data Issues
|
||||
|
||||
The T-Embed test captures have:
|
||||
- Very short pulse sequences (12-22 pulses)
|
||||
- Noisy/incomplete signals
|
||||
- Non-standard formats (Bruce SubGhz File)
|
||||
|
||||
**Solution:** Need real-world captures from actual devices for meaningful testing
|
||||
|
||||
### RTL_433 Coverage
|
||||
|
||||
RTL_433 supports 244 protocols, primarily:
|
||||
- ✅ Weather sensors (433/868/915 MHz)
|
||||
- ✅ Tire pressure monitors (315/433 MHz)
|
||||
- ✅ Remote controls (433 MHz)
|
||||
- ❌ Custom protocols (need manual decoder)
|
||||
- ❌ Proprietary formats (no public spec)
|
||||
|
||||
**Coverage:** ~60-70% of consumer IoT devices
|
||||
|
||||
### Performance Considerations
|
||||
|
||||
- Each decode spawns subprocess (~10-50ms overhead)
|
||||
- No caching yet (repeated decodes reprocess)
|
||||
- Temp files created/deleted per decode
|
||||
|
||||
**Solution:** Phase 7 caching will reduce by 90%+
|
||||
|

|
||||
|
||||
## Next Steps
|
||||
|
||||
### Immediate (Phase 8 - API Integration)
|
||||
|
||||
1. **Update capture submission endpoint** (1 hour)
|
||||
```python
|
||||
@router.post("/submit")
|
||||
async def submit_capture(...):
|
||||
# Add RTL_433 results to response
|
||||
return {
|
||||
'rtl433_decoded': [...],
|
||||
'signature_matches': [...],
|
||||
'best_match': ...
|
||||
}
|
||||
```
|
||||
|
||||
2. **Add RTL_433 info endpoints** (30 min)
|
||||
- `GET /api/rtl433/protocols` - List supported protocols
|
||||
- `GET /api/rtl433/status` - Check availability/version
|
||||
|
||||
3. **Test API changes** (30 min)
|
||||
- Verify JSON response format
|
||||
- Test with Postman/curl
|
||||
- Update API documentation
|
||||
|
||||
### Future (Phase 7 - Optimization)
|
||||
|
||||
1. **Implement caching** (1-2 hours)
|
||||
- SHA256 hash of RAW_Data as cache key
|
||||
- Store decoded results in /tmp/giglez_rtl433_cache
|
||||
- 15-minute TTL
|
||||
- Reduces redundant processing by 90%+
|
||||
|
||||
2. **Benchmark performance** (30 min)
|
||||
- Test with 100+ captures
|
||||
- Measure cache hit rate
|
||||
- Verify <2s decode time maintained
|
||||
|
||||
### Production Testing
|
||||
|
||||
1. **Collect real device captures**
|
||||
- Weather stations (Acurite, Oregon Scientific)
|
||||
- Garage door openers (LiftMaster, Chamberlain)
|
||||
- Tire pressure monitors (TPMS)
|
||||
- Remote controls (433MHz)
|
||||
|
||||
2. **Validation testing**
|
||||
- Verify decode accuracy
|
||||
- Measure success rate
|
||||
- Identify unsupported devices
|
||||
|
||||
3. **Monitoring**
|
||||
- Track decode success rate
|
||||
- Monitor subprocess failures
|
||||
- Log unrecognized devices
