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.

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

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);
