RF Spectrum

Sub-GHz Device Analyzer

Drop Flipper Zero .sub files to identify RF devices. 304 protocols. All analysis runs locally in your browser.

WHAT IS THIS?

WiFi Mothership maps the 2.4 / 5 / 6 GHz spectrum -- your WiFi routers, Bluetooth devices, and cell towers. But there's an entire invisible world below that: the Sub-GHz band (300-928 MHz). This is where your garage door opener talks, your car key fob unlocks, your weather station reports temperature, your tire pressure sensors broadcast, and your doorbell rings wirelessly.

Every one of those devices is constantly transmitting radio signals with unique timing patterns -- like a fingerprint. A Flipper Zero or RTL-SDR dongle can capture these signals as .sub files. Drop those files here and we'll tell you exactly what device made them.

HOW IT WORKS
  1. Capture a signal with Flipper Zero, LilyGo, HackRF, or RTL-SDR
  2. Drop the .sub file on this page
  3. We extract the frequency, modulation, and pulse timing
  4. We match it against 304 known device signatures
  5. You get ranked matches with confidence scores
WHAT WE CAN IDENTIFY
■ Weather stations + thermometers
■ Garage door openers
■ Remote controls + key fobs
■ Security sensors + alarms
■ Tire pressure monitors (TPMS)
■ Doorbells + smart home devices

Your files never leave your browser. Zero server uploads. Zero tracking. Pure client-side analysis.
