Will the Leviton VRCZ4-M0Z zone controller work with SmartThings?

In case anyone here is interested, I was able to get limited capabilities in ST with the VRCZ4 by using the work listed here:

The Device Handler listed on that thread DOES work, but with the caveats mentioned in both threads regarding the inability to use the on/off capabilities of the Z model.

@Ash did you have any follow-up success here?
