2026 verdict
The Sensi Touch 2 smart thermostat is the stronger smart thermostat of this pair, carrying a higher owner rating and a longer three-year warranty while adding a 4.3-inch color touchscreen, dual-band Wi-Fi, humidity sensing, external sensor support, voice control and compatibility with Google Home, Alexa, SmartThings and Home Assistant. The Amazon Smart Thermostat, by comparison, is Alexa-only with a non-touch LED display and a single temperature sensor. Where the Amazon unit fights back is on price, where it is the more affordable option, and on including a trim plate that the Sensi Touch 2 leaves out. Choose the Amazon Smart Thermostat if you want the cheapest Alexa upgrade with the plate included; pick the Sensi Touch 2 smart thermostat if you want a premium touchscreen, dual-band Wi-Fi, multi-room sensing and support for more platforms.
