When we first heard about Ecobee's Smart Thermostat last October, it claimed the device could recoup its $385 price tag within the first 12 to 18 months of use. Whether or not that's the case, you can now find out for yourself. The WiFi-enabled home automation tool, complete with ZigBee expansion slots, is now available to order online from the company's website. The upfront cost includes the $35 access fee for first year of use. Now how long must we wait until someone throws an emulator on this thing?
