Amazon Smart Thermostat vs Ecobee Smart Thermostat Enhanced

The Ecobee Smart Thermostat Enhanced is the better overall pick. It carries a higher owner rating, a three-year warranty versus one year, wider connectivity (dual-band Wi-Fi and Bluetooth), broader platform integrations, and more onboard sensors and alerts. The Amazon Smart Thermostat wins mainly on being the more affordable option.

Ecosystem breadth and sensing. The Amazon Smart Thermostat works only with Alexa and has a single temperature sensor with no alerts, while the Ecobee Smart Thermostat Enhanced works with Alexa, Google Home, Apple Home, SmartThings, Home Assistant and IFTTT, adds occupancy and humidity sensing, and can warn you about sudden temperature drops or spikes.

Only the Ecobee. The Amazon Smart Thermostat is tied to Amazon Alexa alone, so it suits Alexa-centric homes. The Ecobee Smart Thermostat Enhanced spans Alexa, Google Home, Apple Home, Samsung SmartThings, Home Assistant and IFTTT, making it the flexible choice for mixed-ecosystem households.

The Ecobee Smart Thermostat Enhanced. Beyond a temperature sensor it adds proximity/motion, occupancy and humidity sensing plus temperature alerts, and it supports external remote sensors to even out hot and cold rooms. The Amazon Smart Thermostat has only a built-in temperature sensor and no alert features.

Buyers in an Alexa-only home who want the most affordable way to add app control and automatic scheduling to a standard HVAC system, and who do not need occupancy sensing, remote sensors or support for other platforms.

Anyone who wants multi-room comfort with remote sensors, a color touchscreen, temperature alerts and compatibility across Alexa, Google Home, Apple Home and more, and who values a longer three-year warranty over the lowest possible price.
