HackRF One and Harbor Breeze Ceiling Fan

Using a software defined radio (SDR) program call GNURadio, I was able to control a Harbor Breeze ceiling fan from my computer. Imagine replacing "Harbor Breeze" with "Mercedes Key Fob". How secure is your car? 

 PS: I followed the instructions here to install GNURadio on Windows 10. https://www.youtube.com/watch?v=gzrjkZJCBvI 

Files were obtained from here  https://drive.google.com/file/d/1E-fl3C55wpAZyqESjt1S5UyDY5Q_1sy2/view

Most of the wheel files were installed with pip install [package name], e.g.:

pip install lxml

pip install numpy

pip install PyQt5

pip install PythonQwt

pip install Cheetah3

pip install PyOpenGL

pip install setuptools==3.8.1

pip install PyGTK

Finally GNURadio was installed from http://www.gcndevelopment.com/gnuradio/downloads.htm 

Used v3.7.11 because 3.8 threw an error while trying to find the QT plugin.
