I had the same issue, it refused to make any changes via alexa. I couldn’t even get the updated device handler from Stelpro (on another thread) working. I installed Josh Conley’s Stelpro STZW402+ from github, and that fixed my issues. I even created a “heat” group in Alexa with two thermostats, and now I can adjust the two thermostats at the same time.
I did notice that if you manually put the device in ECO mode, Alexa can’t adjust it. I didn’t figure that out until after changing drivers, but I don’t think that was the issue with it.
Clicking the “Add a thing” will put your SmartThings hub in pairing mode.
While the hub is in pairing mode, put your Stelpro Ki Z-Wave thermostat in pairing mode as well (“On” in menu #1) and confirm the selection.
After few seconds, you should see your thermostat on the SmartThings app.
Thanks for taking time creating this smart app that makes the stelpro more functional that the default control of the ST application. I tried creating smart app from your code but this is what I got:

Added this to my hydronic floor line voltage circulator system recently, promptly removed it the day after. Had some strange behaivor as it made a heat call every 10-15 seconds until the room was up to the set point. Took a lot longer to reach temperature and my on demand hot water heater was constantly firing. I expected the heating intervals to be much longer.
I’ve sent a message to Stelpro support for more info as this seems odd.
Has anybody else tried this with hydronic? Here is a screen shot:
The Stelpro Z-Wave thermostat is NOT meant to be used for hydronic control.
It is designed to work with baseboard heaters and convectors only.
As you have discovered, the heat cycle in 15 seconds, therefore you cannot use it on hydronic systems.
Well, it would appear that I do have a problem after all. After upgrading to the latest version of the device handler, everything was working. The day after, I can no longer adjust the setpoint from the Smartthings app.
I can still adjust the setpoint from Google Home, Alexa and even ActionTiles. But not with it’s own app.
it would appear that on their last update, Smartthings changed something that affected your z-wave handler again.
It’s no big deal this time as everything still works perfectly, but the green circle in the bottom, middle tile only says “setpoint” in really small letters.
You can still see your setpoint in between the arrows though.
