It works well with Google Home and other smart devices, allowing easy voice control via Google Assistant or Alexa-compatible devices. Installation is straightforward for most homes and usually takes under 30 minutes, with all necessary parts included. However, some heating or cooling systems may require an additional power accessory, like a C wire, which could complicate setup.

The interface is simple and intuitive, controlled either by touch on the thermostat or through the Google Home app, where you can program schedules and adjust temperatures remotely from your phone or tablet. Energy-saving features include automatic temperature adjustments when you’re away and a Savings Finder that suggests ways to reduce energy use further. It also offers HVAC monitoring that alerts you to potential system issues, helping you avoid costly repairs.

The design is modern and sleek with a matte fog finish and a round shape that blends nicely on most walls. While it lacks a color touchscreen, the clear LED/LCD display is easy to read. Its compatibility covers around 85% of heating and cooling systems, making it a solid choice for many households looking to integrate smart climate control with Google Home. The thermostat requires 2 AAA batteries, which are included, and comes backed by a one-year warranty.

Its polished gold finish and large, bright display with Dynamic Farsight add a stylish and modern touch that’s easy to read from across the room.

The interface is user-friendly, allowing you to control settings via the Google Home app or voice commands, and it even learns your schedule to optimize comfort and save energy automatically.
