Blutek via eBay offers the 2nd-generation Ecobee Ecobee3 WiFi Thermostat with Remote Sensor, model no. EB-STATE3-02, for $189.99 with free shipping. That's tied with our mention from two weeks ago and the lowest total price we've seen for the 2nd-generation model. (It's a current best by $34.) It includes one remote sensor (with support for up to 32), which track temperatures across your home, and adjusts temperatures accordingly. It also features a color touchscreen, timer, and remote control smartphone app.
