Nest was already smarter than your average thermostat, coming with an app that serves as your mobile command and control center. But now that the hardware is integrated with Google Now, it's even easier to communicate with the device. Wish it were a little bit warmer? Just say the word.
We knew this functionality was coming, it was just a matter of waiting for Google to flip the switch. Now that everything's working, Nest will respond to any number of voice commands following the words OK Google, including change the temperature to, turn the thermostat to, set Nest at, alter the temp, and seemingly everything in between.
