Caution for other readers in the US getting an idea: the flipper zero can read radio fan remote signals, but the FCC doesn't allow it to transmit them. I was hoping I could have an "all the remotes" device with the zero, but radio is fairly limited. Perhaps someone will region unlock these.

Sounds like you want one of the 3rd party firmwares. https://github.com/djsime1/awesome-flipperzero https://github.com/djsime1/awesome-flipperzero

  I was hoping someone would point me to something like this, thank you!

The official firmware limits the device to only being able to transmit on frequencies officially supported by the CC1101 chip that handles this range. It's technically capable of transmitting across a wider range but the manufacturer of the chip doesn't support it. Beyond that the official firmware also limits the available frequencies by the device's region setting. There is a full list of the regional limits here: https://docs.flipperzero.one/sub-ghz/frequencies https://docs.flipperzero.one/sub-ghz/frequencies but they are of course intended to limit the device to only frequencies legally authorized for unlicensed remote control type uses in the region in question. It should generally work for any household appliance remotes, as long as the appliance was designed for the region it's being used in. Either way, there's a reason I started both of those paragraphs with references to the official firmware. The device firmware is open source and there are multiple community-developed forks as a result, some of which make these limits configurable by the user.

Unfortunately not, I've got multiple fans from different manufacturers that were sold at major US retailers (i.e., not purchased online) and I can read the remote's transmission but I'm region locked out of transmitting it from the flipper zero. Going to try out some of the custom firmware though, thanks for the details.
