Wifi thermostat


I am wondering if there is a wifi enabled thermostat people are using here. I am pretty much building my own software/system for building a smart house (light switches, outlets, motion sensors, temp/humidity sensors, cameras etc.)

I am looking for a thermostat that I can actually control over wifi, with for example soap/xml, is there anything out there like that?



I might have posted this in the wrong section? if so, sorry.
