Discount online retailer Woot is offering the third-generation Nest Learning Thermostat for $199, a discount of $50 from the device's list price of $249. The offer's good for one day only, or until stocks last.

The third-generation Thermostat comes with Farsight, which wakes up the thermostat when you walk into a room. The Thermostat also has new sensors, alerting you to any changes in your heating setup as well. There's auto-scheduling, the ability to change temperature through your phone or tablet, and integration with an ever-growing list of services.
