Awesome, that is cool to hear RobbMeeX. I look forward to hearing it. I've requested to try the Nest out and even get one for our fall give away (which is coming up very soon!), but I have not gotten any replies sadly.
This is the first site I've found on wifi thermostats. They're all made by Honeywell, a huge and widely known name. They have a selection of four different wifi thermostats, one even has voice control...
Not really sure why you'd talk to your thermostat all that often, but it did give me a chuckle.
Honeywell Wi-Fi Programmable Thermostats
Their lowest cost wifi thermostat, the
RTH6580WF, starts at $120 new on amazon. I'm still comparing the features of this with the other fancier touch screen ones.
