"The goal of this app is to make it trivial to demodulate common RF signals, and provide a digital worksheet for your reverse engineering efforts."

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.
Rollertrol.com carries some but they are quite a bit pricier than the full radius ones elsewhere.
