It learns your routine and suggests schedule tweaks, ships with a Nest temperature sensor for another room, senses presence, humidity and ambient light, and works with Google Home, Alexa, SmartThings and Matter, which also brings it into Apple Home. The Amazon Smart Thermostat is the budget route: Alexa only, a monochrome display without touch, temperature sensing only and a one year warranty, but a fraction of the cost and a trim plate in the box. Pick the Amazon Smart Thermostat to put an Alexa home on a basic schedule for little money, and the Nest Learning Thermostat (4th gen) for a thermostat that runs itself across every major platform.

What the differences mean

Platforms and Matter

The Amazon Smart Thermostat works with Alexa only. The Nest Learning Thermostat (4th gen) works with Google Home, Alexa and SmartThings and supports Matter, which is how it joins Apple Home; Home Assistant support is partial.

Learning and suggestions

Both schedule automatically, but the Nest Learning Thermostat (4th gen) builds its schedule from the temperatures you choose and suggests tweaks over time. The Amazon Smart Thermostat offers no suggestions.

Room sensor

The Nest includes a temperature sensor for another room and can switch between rooms by time of day. The Amazon Smart Thermostat supports no external sensors.

Display

A 2.7 inch high resolution colour display controlled by a dial on the Nest, against a small monochrome LED display on the Amazon model. Neither is a touchscreen.

Warranty and system health

Two years of warranty and a system health monitor on the Nest Learning Thermostat (4th gen); one year and no health monitoring on the Amazon Smart Thermostat.

Which one to buy if

What owners say

Owners of the Nest Learning Thermostat (4th gen) talk about two things above all: the learning, which figures out when they are home or away and adjusts without a manual Home and Away schedule, and the large animated colour display, a clear upgrade over older Nests. The included sensor lets them favour the rooms they actually use, especially overnight, and the adjustable maintenance band is welcomed as a fix for compressor short-cycling. The complaints are practical: some owners found it would not power up without a dedicated C wire where their 3rd gen had worked, control is now limited to the Google Home app, it is built for North American systems only, and Apple Home support comes through Matter rather than a native profile.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
