Which ceiling fan remote? I've been fighting with our bedroom fan, we like the performance but the remote works maybe once out of every 100 presses unless I climb up on our bed and extend my arm into the middle of the fan housing.
I went into the weeds of reverse engineering my Minka Aire ceiling fans with a USB RTL-SDR. In my case the manufacturer's remotes worked fine, but I wanted to integrate it in with Home Assistant. If you're interested, you can see what I did: https://www.riveducha.com/decode-wireless-signal-with-usb-tv...
I used a USB RTL-SDR ($15) and a Raspberry Pi to receive and transmit, but I think the Flipper Zero can do it all-in-one.
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.
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 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.

Confused: if it (even irregularly) works under those conditions, have you tried not doing such, and see if it works more often?
