Amazon Smart Thermostat vs Nest Learning Thermostat

The Nest Learning Thermostat is the better overall choice, with a higher owner rating, a two-year warranty, self-learning scheduling, more sensors and alerts, and support for Google Home, Alexa, SmartThings, IFTTT and Matter. The Amazon Smart Thermostat's main edge is being the more affordable option.

Automation and ecosystem. The Amazon Smart Thermostat works only with Alexa and relies on preset schedules with a single temperature sensor, while the Nest Learning Thermostat learns your routine to build its own schedule and works across Google Home, Alexa, SmartThings, IFTTT and Matter.

The Nest Learning Thermostat is designed to observe your habits and build a heating and cooling schedule on its own. The Amazon Smart Thermostat supports automatic and manual scheduling but does not learn your routine the way the Nest does.

The Nest Learning Thermostat. It adds occupancy, humidity and ambient-light sensing plus temperature alerts and works with Google Home, Alexa, SmartThings, IFTTT and Matter. The Amazon Smart Thermostat has only a temperature sensor and is limited to Alexa.

Buyers in an Alexa household who want the most affordable route to app control and scheduling, and who do not need self-learning behavior, extra sensors or multi-platform compatibility.

Anyone who wants a thermostat that programs itself, prefers broad ecosystem support including Matter, values richer sensing and a longer warranty, and likes the choice of metal finishes to match their decor.
