Bottom Line
Choose it if you want strong app control, flexible scheduling, and room-sensor comfort. Skip it if you only need basic smart thermostat control or will not use the premium extras.
Best for
Homeowners who want a polished smart-home thermostat with strong app control, flexible schedules, and room-sensor-based comfort management. It especially fits people already using HomeKit or Alexa and those who like reviewing energy data.
Not for
Shoppers who mainly want a cheaper thermostat for basic heat and cool scheduling. It is also a weaker fit if you expect premium away and presence features to work perfectly without adding enough sensor coverage.
Verdict
The Ecobee Smart Thermostat Premium comes through in review after review as a polished, easy-to-use smart thermostat with strong app control, flexible scheduling, readable hardware, and genuinely useful room-sensor support. HomeKit, Alexa, broad HVAC compatibility, and rich reporting are recurring strengths, and several reviewers also liked its premium materials and modern interface. The tradeoff is cost and complexity: multiple reviews say the higher price is hard to justify if you will not use the extra features, and one long-term user found away-mode behavior less convincing without broader sensor coverage. Overall, the evidence supports it as a feature-rich flagship thermostat, but the Premium case is strongest for households that will actually use its ecosystem, sensing, and comfort tools.
