Amazon Smart Thermostat vs Sensi Smart thermostat

The Sensi Smart thermostat is the better overall pick, winning on price, owner rating, a three-year warranty, wider platform support, humidity sensing and voice control. The Amazon Smart Thermostat's remaining draw is its Alexa-native simplicity and an included trim plate.

Compatibility and value. The Amazon Smart Thermostat works only with Alexa, while the Sensi Smart thermostat works with Google Home, Alexa, Apple Home, SmartThings and Home Assistant, adds humidity sensing and voice control, and does so at a lower price with a longer warranty.

Only the Sensi Smart thermostat supports Apple Home, alongside Google Home, Alexa, SmartThings and Home Assistant. The Amazon Smart Thermostat is limited to Amazon Alexa, so Apple households should choose the Sensi.

No. The Sensi Smart thermostat includes humidity sensing in addition to temperature, while the Amazon Smart Thermostat has only a built-in temperature sensor.

Buyers who specifically want an Amazon-branded thermostat in an Alexa-only home and value the included trim plate, accepting a shorter warranty and narrower platform support.

Anyone who wants the better all-round value: a lower price, a three-year warranty, humidity sensing, voice control and compatibility with Google Home, Alexa, Apple Home, SmartThings and Home Assistant.
