Make your own version of realtrigger

Hello, I am working on a little vr survival, and I want to implement realiteer's RealTrigger into my game, but they are taking ages to release the SDK and I am tired of waiting (I have been waiting for 2 years now). I have seen many different examples of RealTrigger like controllers that work right out of the box on specific games. That means that there is a way to implement some type of code tracking, does anybody know how to make your own version of it?? Or atleast any way to get something like RealTrigger in my VR game. If so I would really appreciate it

Thanks in advance BTW
