+import requests
+
+response = requests.get('http://localhost:8000/api/rtl433/status')
+data = response.json()
+
+if data['available']:
+    print(f"RTL_433 is operational")
+    print(f"Version: {data['version']}")

+        "timestamp": "2026-01-14T12:00:00Z"
+    }],
+    "data_source": "test"
+}
+
+# Upload file
+files = {'files': open('capture.sub', 'rb')}
+data = {'manifest': json.dumps(manifest)}
+
+response = requests.post(
+    'http://localhost:8000/api/v1/captures/upload',

+            for device in capture['rtl433_decoded']:
+                print(f"    - {device['manufacturer']} {device['model']}")

+
+---
+
+## 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
+
+---
+
+## Changelog
+
+### Version 1.0.0 (2026-01-14)
+
+**Added:**
+- `GET /api/rtl433/status` - Check RTL_433 availability
+- `GET /api/rtl433/protocols` - List supported protocols
+- `GET /rtl433/protocols/{id}` - Get specific protocol info
+- RTL_433 decoding in `/api/v1/captures/upload`
+
+**Updated:**
+- Upload response now includes `rtl433_decoded[]` array
+- Upload response includes combined `matched_devices[]` array
