The short answer: I don’t know how to do it in windows. It only works with the raspberry pi. That does not mean it could not ever work with windows, but it currently does not.
Functionally there is a python library called cwiid that interfaces with the wii remote and the bluetooth. There is a maslowpendant service that uses the cwiid library to connect to the controller via bluetooth and then interfaces with webcontrol over the web socket similar to the web page interface with some lines of code added to main.py to interpret the input. I can show you how it works, but I’m not sure how to launch system services in windows without writing new code.
