Ok - I got it connected to ST using the Zensys tools (very little documentation for that program that I could find!).
However, I couldn’t get openHAB to do anything with it - my nerd-fu is too weak. So I decided to try out Domoticz.
The z-stick is still recognized by ST and I added it as an item in the Domo hardware tab, but still no communication between the two.
Now I’m trying to get ST to forget the z-stick and I can’t figure out how to do that! Removed it from Domo, tried to get Zensys to make it disconnect from ST while in “exclusion mode,” but nothing. Any idea what I’m doing wrong?
