I built a community Sub-GHz signal database for Flipper Zero — open source, free, contribute via PR
Hey r/flipperzero,
I put together a community signal database where you can browse,
search and download .sub files directly in the browser — no app,
no login, just a static site backed by a GitHub repo.
🔗 https://og34.github.io/flipper-signal-db/
What it does:
- Search and filter signals by category, frequency range or protocol
- Click any signal card to preview the .sub file content
- Download directly to copy to your Flipper SD card (SD:/subghz/)
- Star signals as favorites (saved in your browser)
- Light/dark mode, works offline (PWA)
Categories so far: garage doors, car keys, intercoms,
weather stations, custom
How to contribute:
The whole thing is driven by signals.json in the GitHub repo.
Drop your .sub file on the site and it auto-detects frequency +
protocol from the file. Generates the JSON entry for you,
then just open a PR. CI validates your submission automatically.

Currently only has 5 demo signals — would love for the community
to fill it up. If you've got captured signals sitting on your SD
card, this is a good place to share them.
Feedback welcome!
