  Playground (and dump) of stuff I make or modify for the Flipper Zero (by UberGuidoZ)

Apparently at least some use 315 MHz. There is software to program them at https://github.com/UberGuidoZ/Flipper/tree/main/Sub-GHz/Gas_Sign which is intended for legitimate use only. I learned this from another thread and I know nothing more about the subject.
