Control your Kasa TP-Link smart switches from your Windows 10 device.
This is a .NET program to control Kasa TP-Link smart switches from your Windows 10 device.
I also have a Python-QT version that works on Windows/Mac OS X/Linux but it's not as modern: https://github.com/clorteau/kasa.
To install this Windows 10 version just get it from the Windows Store.
Basically what this does is send a command to the switches by packing the command string length as a Big Endian followed by an Auto-Key XOR of the command. I thought it was interesting to implement.
