This is a port of nuttytree's ST DTH below:
[UPDATE as of 3/26/18 - please see 2nd post below for details]
I modified this DTH to make it Hubitat compliant. My changes are noted in the comments at the top of the code. I have not tested the ability to associate other Zwave devices (as I have no use for this function) but the double Tap functions work perfectly.
Note: based on the thread in the ST forums, you may need certain firmware versions of this device for it to work properly. If you have part 14294 and the manual includes "association group" information, you should be good to go.

Thanks to nuttytree for making this great driver. Hopefully he makes the jump to Hubitat soon as well.
