The Nest Learning Thermostat has learned a new trick: It lights up and displays the temperature or the time when you walk into a room where the device is located.

Nest calls this feature Farsight, and it's available in the newly released third-generation Nest Thermostat. Earlier iterations of the product self-illuminated only when someone passed within two or three feet of the device.

The latest Nest Thermostat has been redesigned. It protrudes from the wall less, thanks to its reduced profile. It features a larger display with higher resolution -- 229 pixels per inch (PPI), 25% more than the previous generation. This makes temperatures displayed through Farsight sharper and easier to read when viewed from afar.

Nest has added additional temperature sensors to make its thermostat more accurate. It also includes a new furnace monitoring mode called Furnace Heads-Up.

Most furnaces include an automatic shutoff function to avoid overheating. The Nest Thermostat has been programmed to monitor shutoff events. If it detects a pattern, it will display a Heads-Up alert on-screen and in the Nest app twice a year, and will include a notification in its monthly energy report email message.

Nest plans to make Furnace Heads-Up available to owners of first-generation and second-generation Nest Thermostats later this year.

Nest Thermostat works in conjunction with other Nest products, like the Nest Protect smoke detector, and the Nest Cam. For instance, Nest Protect's sensors expand the Nest Thermostat's awareness of a structure's occupants beyond the room where the thermostat is installed. The presence or absence of people in a room informs the thermostat's temperature settings.

According to Nest, its thermostat has helped people save over 4 billion kWh of energy in millions of homes around the globe since 2011. Based on studies that suggest the device can save 10%-12% on heating bills and 15% on cooling bills, the company claims its thermostat pays for itself in two years or less.

The third-generation Nest Thermostat is available from Nest.com, Amazon.com, and BestBuy.com.

The company says it will be available soon at Best Buy locations, the Google Store, Lowe's, Home Depot, Sam's Club, Target, and Verizon Wireless at a suggested retail price of $249. The second-generation Nest Thermostat is now being offered at $199 at select retailers.
