ecobee Smart Thermostat Premium review

The smart thermostat most comparisons recommend for mixed-ecosystem and Apple homes, thanks to its included room sensor and broad platform support. Google-only households may prefer the Nest Learning Thermostat's design, and ecobee's smoke-alarm listening needs a subscription.

A smart thermostat with a 4-inch 540x540 touchscreen, a SmartSensor included for room-by-room comfort, radar occupancy sensing, built-in air-quality monitoring and Alexa built in.

Shortlist what's worth buying

We start from models that are actually sold and supported in the US, and drop anything with a pattern of reliability, app or support problems.

2

Research, not spec-sheet copying

We weigh manufacturer specs against independent lab measurements, professional reviews and long-term owner reports, and write down where they disagree.

3

Score with the trade-offs visible

Each product gets a 10-point score against the criteria that matter for its category, with the pros and cons that produced it.

Commissions don't pick winners

We earn from some links, but which store pays more never decides what we recommend. If the best option is somewhere we don't earn, we still say so.
