Nest Learning Thermostat review: pretty smart

Who’s the fairest of them all?

When my C wire went bad on my old system, the non-learning Nest Thermostat I was testing kept disconnecting from Wi-Fi and eventually stopped working when its AA batteries died. Even without access to the full range of compressor settings, I was still able to test the Nest Learning Thermostat, including its signature function: Smart Schedules. Last week, it was in the high 20s here in South Carolina, and instead of dropping all the way down to 62 degrees Fahrenheit (my heating threshold in eco mode) when I left the house, it only went down to 66F and was back to a comfortable 68F within a few minutes of my return.
