What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
ecobee Smart Thermostat Premium
Three whitelisted testers (Tom's Guide, TechHive, Reviewed) rate the Ecobee Smart Thermostat Premium a top-tier smart thermostat. Reviewed lab-tested temperature accuracy against a NIST-certified thermometer; Tom's Guide and TechHive evaluated it hands-on qualitatively. All praise the premium redesign, easy app-guided install, broad smart-home compatibility, and the included occupancy-sensing SmartSensor. Shared gripes: a weak built-in speaker, a limited air-quality sensor, and a high price. (3 sourced reviews, 1 lab-tested.)
Praised: Premium redesign — zinc body, glass display, responsive larger touchscreen; Broad smart-home compatibility (Alexa, Siri/HomeKit, Google, SmartThings, IFTTT); App-guided installation is quick and easy.
Flagged: Built-in speaker sounds weak/tinny; Air-quality sensor is limited — no particulate readings, cannot trigger HVAC fan; Expensive / premium price.
