GoControl Thermostat, Z-Wave, Battery-Powered, Works with Amazon Alexa


I am looking for a thermostat to use with ST hub. But I’d also like to control it through Amazon Echo (Alexa)
I found this one:

It says “works with Amazon Alexa” but I don’t know how.
I believe it can work with ST hub as a standard z-wave thermostat. But how can I integrate it with Alexa ?


any ideas ?

Anyone have more insight on this thermostat? It’s on sale and local hardware store. Was looking for a decently priced one to work with my Smartthings devices. What all works or does not work?
