Remember Nest? The already-sleek thermostat just got a facelift, now measuring in at roughly 20% thinner and sporting a one-piece steel band exterior that also doubles as a control knob. Compatibility with existing systems has also been improved to work with nearly every existing system. Software-wise, the new Nest still supports smartphone control, learns your schedule more accurately than before to heat/cool your home accordingly, and saves you energy – and money – bit by bit each day.
