Looks fun! I did some reverse engineering for the RF sensors of my weather station a few weeks back, I used gnuradio, audacity etc but it was all 'manual', ie feeding the .WAV capture file to my own program and trying to find the decoding [0]. Turns out it was a known protocol of course, but it was still fun! Next time I know where to look for the proper tools, this looks awesome!
