Ecobee Smart Thermostat Premium

GRADE A — Independently Tested, With A Stat Left Out On Purpose

Wirecutter picked this as its top overall smart thermostat, and named a concrete reason: no rival at a comparable price bundles a room sensor, an air-quality sensor, and a built-in voice assistant together.

A "9.2/10 consensus score" and a "449% five-year ROI" figure circulate across a number of SEO aggregator sites covering this thermostat. We tried to trace either number back to a named lab, publication, or methodology and came up empty, so we're leaving both out rather than repeating them.

It only controls an existing central heating/cooling system — it has nothing to retrofit onto a window unit or a portable air conditioner.

What's In The Box

The Premium tier bundles a Wi-Fi touchscreen thermostat with a wireless remote room sensor, a built-in air-quality sensor, and an integrated Alexa voice assistant speaker — four functions most competitors sell separately or don't offer at all in one unit.

Who Actually Makes It

Ecobee was founded in Toronto in 2007 and was among the first companies to bring a Wi-Fi-connected thermostat to market. In November 2021, Generac Holdings — a publicly traded company — announced it would acquire Ecobee in a deal valued at up to $770 million. That's a verifiable corporate transaction with a paper trail, not an anonymous or undisclosed manufacturer.

The Independent Pick, And The Stat We Wouldn't Repeat

Wirecutter's editorial team named this model its top overall pick among smart thermostats, crediting the sensor-plus-air-quality-plus-voice-assistant bundle at this price point as the differentiator no competitor matches. That's a named, checkable source making a specific, falsifiable claim — the kind of evidence this desk weights heavily.

By contrast, a 9.2-out-of-10 "consensus score" and a 449% five-year return-on-investment figure show up repeatedly on aggregator sites covering this same thermostat, with no lab, publication, or methodology attached to either one. We went looking for the origin of both numbers and couldn't find it, so neither appears anywhere else on this page.

What The Savings Number Really Covers

ENERGY STAR publishes a category-wide estimate of roughly $50 to $145 a year in typical savings for smart thermostats as a product class. That figure describes the category, not a number ENERGY STAR calculated for this specific model, and it will move depending on climate, existing equipment, and household habits.

Where To Check Current Listings

With an independent top pick behind it and a verifiable corporate history, this is a case where the product itself is the pick — not a substitute or workaround.
