Great guide.
I stumbled upon this when I realised that my Debel awning was using a Dooya motor and remote.
I did not use your cool system with the soundcard to sniff the RF codes, but instead used my RTL-SDR usb receiver, since I already had it laying around
After finding the codes I programmed an Arduino with it and connected it to my OpenHAB installation. Now the awning can be controlled with the OpenHAB app, and my wife just loves it
Just wanted to point it out for others looking for RF codes for Debel awnings.
