It’s not just a functional device; it’s a design statement that can genuinely enhance a home’s interior. The Polished Gold review unit, in particular, adds a touch of elegance to any wall.
The design upgrade is striking, headlined by a significantly larger domed crystal display (60% bigger than its predecessor) and minimized bezels. This gives it the appearance of a sophisticated piece of jewelry rather than a typical gadget. The reflective glass surface has an intriguing depth and cloudiness, drawing attention without being intrusive. Unlike earlier Nest models with pronounced edges, the 4th Gen features a subtly integrated bezel where the domed glass seamlessly merges, creating a smooth, rounded aesthetic. It exudes a premium feel, almost too beautiful to touch, yet inviting interaction due to its playful design.
Interaction is intuitive and satisfying. The thermostat incorporates a rotating mechanism for navigating menus and adjusting temperature, along with a push-button function for selections. This interaction model will be familiar to users of previous Nest thermostats, but the 4th Gen elevates the experience with a more refined and pleasurable tactile feel.
Farsight Display and Digital Clock. A notable addition is “Farsight,” Nest’s take on an always-on display, offering customizable information. Past Nest thermostats primarily displayed the current temperature when approached. The 4th Gen expands this with customizable clock faces, current weather conditions, humidity levels, “feels like” temperature readings, outdoor air quality, and the date.
This enhanced display provides valuable at-a-glance information. While smartphones offer similar data, the Nest Thermostat’s Farsight feature presents it in a contextually relevant and readily accessible manner within the home environment. It’s a feature that quickly becomes indispensable, providing useful daily information in a seamless, unobtrusive way.

Included Nest Temperature Sensor (2nd Gen). The inclusion of the Nest Temperature Sensor (2nd Gen) in the box is a major highlight. While its cost is factored into the $280 price, its value is undeniable. Previously a separate purchase, it’s now an integral part of the Nest Thermostat (4th Gen) experience right out of the box.
For multi-story homes, or homes with rooms that experience temperature variations, the temperature sensor is particularly beneficial. It allows the thermostat to regulate temperature based on the sensor’s readings, not just the thermostat’s location. In my two-story home without multi-zone HVAC, the sensor effectively simulates this, allowing the thermostat to consider upstairs temperatures when heating or cooling. This feature alone significantly enhances home comfort.
Beyond multi-story setups, the sensor is adaptable to address temperature inconsistencies within a home. It can be moved to different rooms throughout the day, enabling the thermostat to optimize temperatures for specific areas as needed. Schedules can also be configured to prioritize readings from the sensor, the thermostat, or a combination, offering highly customizable temperature management. For anyone with a Nest Thermostat, the temperature sensor is an essential addition, and with the 4th Gen, it’s conveniently included.
Google Home App Integration. Transitioning from the older Nest Thermostat E, primarily designed for the legacy Nest app, to the 4th Gen, which exclusively uses the Google Home app, was a significant shift. Initially, the Google Home app wasn’t my preferred platform. However, for the Nest Thermostat (4th Gen), it provides a surprisingly positive user experience. Setup is straightforward, and navigating settings and adjusting preferences is intuitive. The app features a clean, bubble-style layout with a prominent temperature dial and easy access to heating/cooling modes, sensor data, fan settings, schedules, and the energy dashboard, along with humidity readings.
Drilling down into each section reveals more detailed information and options. Reviewing and customizing automated schedules is remarkably simple, a stark contrast to the often cumbersome schedule adjustments in the older Nest app. Adjusting Farsight options, sharing device access, managing notifications (like air filter reminders), setting temperature preferences, and enabling geofencing for home/away assist are all easily accessible within the app’s settings.
Despite initial reservations about the Google Home app, particularly compared to the streamlined Nest app of the past, its integration with the Nest Thermostat (4th Gen) is well-executed and functional.
