Glad to hear you've got a Hubitat now! 
It doesn't appear to have been mentioned in any of the posts above, but Mike did create a "Basic Z-Wave Tool" for Hubitat that serves a similar purpose, though it doesn't appear to do quite as much (setting associations, etc.): Super basic Z-Wave parameter tool. I've only used it to change Z-Wave parameters if the driver didn't expose something directly. Good luck with your porting efforts--there are a few threads on the forum you can search for about differences between ST and HE that affect code-writing if you haven't seen them already.
