Zooz Z-wave firmware 7.22.1
EISY IoX 5.9.1
The Zooz 800 Z-wave USB stick does work. It was initially showing "Zmatter Z-wave not responding". I had to use this port reassignment to get to to respond:

RCS TZ45R Thermostat seems to work nicely. The one thing I didn't like was the way it integrates with Scenes. So, I just moved the commands to programs. You can set all the common thermostat things AND all of the settings but they aren't intuitive. But you can set all the settings below from IoX/EISY. UD Mobile works as a thermostat. I did have to do a resync; easy peasy. Moving from a Venstar T1700, this is definitely a step up. The reason for the change out was a failure of my upstairs Venstar unit. Downstairs is fine for now, but it will be an easy choice to go to a TZ45R when it fails.
