It isn&#x27;t a smart&#x2F;learning thermostat, but I&#x27;ve been very happy with my <a href="http:&#x2F;&#x2F;www.radiothermostat.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.radiothermostat.com&#x2F;</a> CT30 - and it hasn&#x27;t left me in the cold. There is a newer model now, but you can get them with a Wifi or z-wave module. It has a json API and of course that means there are free apps too.<p>I easily added a few controls to my own home automation system and now I can control it from anywhere and I don&#x27;t need a 3rd party (other than the internet) involved. What do I like the most? Since I&#x27;ve set it up I haven&#x27;t had to physically touch it. Programming it through json or an app is easier than the buttons on it. Now if you want a smart&#x2F;learning t-stat, you&#x27;ll want something else.
