Nest is making waves at CES by announcing parnterships with 15 companies including LG, Big Ass Fans, Mercedes-Benz, and August Smart Locks, on a series of collaborations it is calling Works With Nest. It has worked with Whirlpool on a smart washer-dryer set that interfaces with your Nest thermostat to find out when you're home and when you're away. (The dryer, for instance, can switch to a longer, lower-temparature cycle that consumes less energy.)
