I reverse engineered a so called social alarm a bit ago. You can find it here: https://github.com/mrquincle/social_alarm

Gnuradio was also new to me. However with two HackRFs I could do the entire thing. First replay attacks. Then trying to get the code by building up a set of processing blocks. Last synthesis of the complete signal.

Very nice to do! Felt great!
