Full Smart Thermostats comparison in 2026

Updated October 2026
Data from Amazon and official Google site.
2026 verdict
Anything besides Alexa in the house? Then the Nest Thermostat is the better budget smart thermostat of the two, since it also works with Google Home, Apple Home and SmartThings.

It senses much more, with humidity, proximity, occupancy and ambient light sensors behind a presence-aware eco mode, sends temperature alerts, shows time and weather on a 2.4 inch colour display and connects on 2.4 and 5 GHz Wi-Fi with Bluetooth, in a choice of four colours. The Amazon Smart Thermostat is the lower priced and better rated of the pair, includes a trim plate, and holds manual and automatic schedules with energy saving behaviour, but Alexa is its only listed platform and its monochrome display shows the temperature alone. Both come with a one-year warranty, and neither supports Matter or remote room sensors. Buy the Nest Thermostat for a mixed or Google home that wants presence sensing, and the Amazon Smart Thermostat for the cheapest route to Alexa-controlled heating.

What the differences mean

Platforms

The Amazon Smart Thermostat is listed with Alexa and no other platform: no Google Home, Apple Home, SmartThings or Matter. The Nest Thermostat works with Google Home, Alexa, Apple Home and SmartThings, with partial Home Assistant support, so it can follow you if your ecosystem changes.

Sensors

The Nest Thermostat measures humidity and has proximity, occupancy and ambient light sensors that let its eco mode notice an empty house. The Amazon Smart Thermostat measures temperature only, so it works from its schedule and your commands.

Display

The Nest Thermostat has a 2.4 inch colour screen that shows temperature, time and weather. The Amazon Smart Thermostat has a monochrome LED display that shows the temperature and not the time or weather.

Alerts

The Nest Thermostat sends temperature alerts when the house gets unexpectedly hot or cold. The Amazon Smart Thermostat lists no alerts of any kind.

Scheduling

The Amazon Smart Thermostat is listed with manual and automatic scheduling. The Nest Thermostat relies on a guided manual schedule in the Google Home app plus its presence-based eco mode.

What owners say

Nest Thermostat owners are mostly upgrading from an old dial or an unused programmable thermostat, and they report what they bought it for: lower heating bills, occasionally a rebate that covered much of the cost, and the convenience of pre-heating or pre-cooling from the phone. The eco and away mode, which uses phone location and the motion sensor, gets credit for cutting waste, and the install takes about half an hour with the app. The complaints are about the fine print: a C-wire or Nest's adapter is required, everything runs through the Google Home app, eco mode can be too aggressive and fiddly to change, the touch strip feels less premium than a dial, and it only works with North American heating systems.

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.
