Remember how Nest promised that you’d one day use Google Now to control your thermostat? That day is very nearly here. Droid-Life has discovered that the search tool is responding to temperature requests, and will show you a Google Now card when the thermostat is cooling or heating your home. However, you can’t actually use this feature yet — you need to authorize your Google account to make this work, and the necessary website isn’t completely ready. Even so, it’s clear that you’ll soon be commanding your climate using little more than your voice.
