I did exactly the same thing for a different brand of DIP-switch-addressable remote-control fan back in 2016. It's been wonderful.
It wasn't that hard; I used gnuradio with an SDR to see what the remotes were sending and just pressed buttons and flipped switches until I figured out what all the bits were. There was no encryption whatsoever.
