This guy did it the hard way, I automated my lights in a similar way with simple command line tools (./listen <pin> to get code and ./send <pin> to send.)

In the post I actually outlined that I had actually captured enough data from a handful of remotes that I could have replayed these captures to control the blinds (and I even had a rig set up to do this).
But that's not what I wanted to do. I was interested in working out what was happening with these remotes and being able to generate as many arbitrary remote codes as I wanted.
Going the step further to reverse engineer the protocol is something I did as a learning (and fun and challenging) exercise. I've definitely picked up skills through this process that I can apply in similar projects later down the track.
