If you enjoy controlling things from your phone or by voice, this thermostat works well with Alexa, Apple HomeKit, and Google Assistant, plus it’s compatible with the latest smart home standards for easy integration.

This can help reduce energy bills, with potential savings of around 12% for heating and 15% for cooling. The included Nest Temperature Sensor lets you manage different rooms more precisely, so you can avoid hot or cold spots.

The design is sleek and modern, with a large, bright touchscreen display that adjusts automatically based on the lighting and can show useful info like the time or weather. The thermostat also notifies you before making energy-saving schedule changes, giving you control over adjustments. Installation is generally straightforward, though some older or unusual HVAC systems might need professional help or additional wiring. Since it relies on Wi-Fi, remote controls depend on a stable internet connection. While setup and features might seem a bit complex initially for those new to smart home tech, they are manageable with the Google Home app. This thermostat suits anyone looking to upgrade to a smart, energy-efficient system that blends well with popular smart home ecosystems and offers hands-off comfort management with some manual control when needed.

The thermostat learns your schedule through the Google Home app, allowing it to create an energy-efficient heating or cooling plan.
