The Google Nest Learning Thermostat (4th Gen) paired with the Nest Temperature Sensor (2nd Gen) has been an excellent upgrade for our home. Installation was straightforward, and the setup through the Google Home app was smooth and intuitive. The thermostat looks sleek and modern, and the display is clear and easy to read. The learning feature works well—after a short adjustment period, it began automatically optimizing our heating and cooling schedule without constant manual input. The temperature sensor is a great addition. It allows us to prioritize comfort in the rooms we actually use, rather than relying solely on the thermostat’s location. This has made a noticeable difference in maintaining consistent temperatures, especially during the night. Energy efficiency is another strong point. We’ve already seen more balanced heating cycles and less unnecessary runtime, which should translate into savings over time. Overall, this is a smart, well-designed product that delivers on both comfort and convenience. Highly recommended for anyone looking to modernize their home climate control system.

Easy to install, nice looking and programmable. Supplied already with the wall plate (white plate + black thermostat) Even able to operate the central dehumidifiers ( see the product manual) I would recommend this product.

Better than that old T we got with the house. Super easy to use and the multiple sensor function is great feature. Has helped with efficiency in the house. Wifi feature works great. Display is super easy to use and you can use your phone. Noise level is none.

Yikes what a neat device! It does learn from your daily movements to adjust either heating or cooling regime when you leave the house. It compensates for outside temps and figures out the time required to meet your set temps when you return to the home. There are many settings for fan timings ( to circulate stall air). To use the devices many features one should use the Google home app which requires WiFi. Should this be a ‘no -no’ it can be easily programmed directed by using the thermostat. Our one negative comment is the price. A Generation 3 unit costs less but lacks conservation features of this unit. Time will tell if the units features will save us energy costs. Google emphasized it will save.

Works as expected, now with Matter so appears in HomeKit. Full functionality in Google Home. Was able to mount it on existing wall plate which saved time. Additional sensor is a nice bonus.
