A thermostat that knows you better than you know yourself? Okay, maybe not you, but definitely your heating and cooling habits.

The Google Nest Learning Thermostat (3rd Gen) is like having a personal assistant for your home’s comfort — one that learns your daily routine, adapts to your preferences, and keeps your space cozy without wasting energy.

After just a week, Nest figures out when you’re home, when you’re out, and how you like your mornings — no more fiddling with settings or running the heat for an empty house. You can control it remotely through the Google Home app or hands-free via Google Assistant or Alexa, whether you’re on the couch or halfway across the world.

Its minimalist design looks great on your wall, and features like Home/Away Assist, Energy History, and the Nest Leaf (a subtle nod when you’re saving energy) make it both practical and satisfying to use.

Plus, this one’s Grade A refurbished, meaning it’s been inspected, tested, and cleaned to near-mint condition.

If your home isn’t smart yet, this is an easy first step that literally pays for itself over time.

Get this like-new Google Nest while it’s $99.99 (MSRP $249) for a little while longer.
