Nice! I just saw this thread
Sorry I missed it. Too much information and many times I will drop bits all over the place.
Glad to hear you got it working. Did you use the SmartThings code or the ported Hubitat code. I "think" the Hubitat code is a little behind but the ST code will work directly in Hubitat as long as you comment out the correct lines as you noted and you set the correct switches at the top of the code as directed in the code comments.
Let me know how it goes I have Hubitat at my house and I have not had much time to play with it. It just works so far. I want to get a better solution for android/ios app to ARM/DISARM and see the current state but I have nto played with the "cloud" panels much yet.
Best
