Google’s Nest unit today launched its newest thermostat. At $129, the new thermostat is the company’s most affordable one yet, but it’s also the first to feature a new swipe and tap interface on its side, as well as Google’s Soli radar technology to sense room occupancy and when you are near the device.

Soli, it is worth noting, is not being used for enabling gesture controls. Instead, because the design team wanted a solid mirror finish on the front, Nest decided to use it purely for motion sensing.
