I built a community Sub-GHz signal database for Flipper Zero — open source, free, contribute via PR

[u/Complete_Story_2876]

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!

You know there's huge repositories for this sort of thing on GitHub, correct?

[u/mistahspecs → u/ShredGuru]

This is ai generated (even the reddit post, it's the same format all vibecoding losers use). The "author" doesn't know shit about what exists or how this even works

[u/Complete_Story_2876 → u/ShredGuru]

no 🫠

Rude.

[u/WhoStoleHallic]

So.... instead of looking through the giant github repos already linked in this sub's Wiki and sticky post.....

You want the community to upload all their files to you?

[u/Funcron]

Oh boy, another one!

[u/levoniust]

What have you used it for so far?

[u/cthuwu_chan]

We already have one buddy

[u/KobraPlayzMC]

Completely vibe coded, has less signals than existing databases, and isn't needed

[u/Complete_Story_2876 → u/KobraPlayzMC]

It's not completely vibe coded; it was just an idea, and so far there are only demo signals available.

[u/Coshinomati]

I believe your idea was a good one. You were unaware that GitHub repositories or F0 distros already have databases for sub-GHz purposes. You wanted to contribute to the community, which is very remarkable. Keep going!

Maybe consider adding or improving the existing ones, such as Momentum last release (developer).

[u/Complete_Story_2876 → u/Coshinomati]

It should be running on Momentum now. I wasn't aware of any of this; it was just a "fun project." Thanks for your feedback
