Google Nest Learning Thermostat (4th Gen) + Nest Temperature Sensor (2nd Gen) — Obsidian | Energy-Saving Smart Home Thermostat

Smart Comfort, Smarter Savings for Your Home

The Google Nest Learning Thermostat (4th generation) pairs elegance with intelligence. It observes when you adjust temperatures, how your home responds to outdoor weather, and your daily routines. The large display with Dynamic Farsight makes essential information easy to read from across the room, so you stay in command without interrupting your flow.

Beyond a stylish upgrade, this thermostat offers practical energy management. It can help reduce heating and cooling use by learning your patterns and adapting to shifts in your schedule or the weather outside. The result is a thermostat that feels responsive and unobtrusive, quietly supporting a comfortable home environment.

Included with the system is the Nest Temperature Sensor (2nd Gen), designed to help manage hot or cold spots by targeting specific rooms. When used together, you set the desired temperature in the Google Home app for each room at different times of day—so you get comfort where you want it, when you want it.

Your home, your control, your data

Control is effortless via the Google Home app, so you can adjust settings on the go from your phone, or use voice commands with Google Assistant and compatible speakers. The Thermostat also supports Matter for simpler smart home integration, enabling a seamless setup with other devices in your ecosystem.

• Up to 31% potential savings on heating and cooling bills when used with compatible systems.
• Works with most 24V heating systems—gas, electric, oil, forced air, heat pump, or radiant—often without a C-wire.
• Dynamic Farsight and a 60% larger display help you see essential info from across the room.

Smart climate behavior extends beyond simple scheduling. The thermostat learns how outdoor temperatures affect indoor comfort and adapts accordingly, pausing or reducing activity to conserve energy when appropriate. An Adaptive Eco mode further supports energy-efficient temperature management while you’re away, and it returns to a comfortable setting when you return home.

• New natural heating and cooling behavior anticipates sun and warmth from windows to reduce unnecessary runtime.
• Adaptive Eco helps find an energy-saving temperature outside your regular routine and returns you to comfort after you return.
• Easy, do-it-yourself installation with robust compatibility for common home systems; the Nest Compatibility Checker can help you confirm.

In everyday life, you’ll notice how these features translate into a calmer, more even indoor climate. It’s the feel of a home that’s responsive to your life—not too hot, not too cold, with fewer abrupt temperature swings. While results vary by home and usage, the Nest system offers flexible options you can enable or adjust as you see fit, without promising guaranteed outcomes.
