The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the ecobee Smart Thermostat Premium is positioned as the do-everything flagship, adding a built-in air quality monitor, an included smart room sensor, and on-device Alexa. CNET covered it as a tested pick, and r/HomeKit owners called it 'great' with HomeKit—though they noted scene and automation bugs once you run more than one unit. A high-trust r/homeassistant thread separately praised ecobee for working locally through HomeKit and surfacing useful HVAC and insulation diagnostics.
What reviewers liked
- Includes a remote smart sensor plus a built-in air quality monitor not found on cheaper units
- r/HomeKit and high-trust r/homeassistant users praise local HomeKit control and HVAC diagnostics
- Built-in Alexa adds voice control without a separate speaker
- Frequently eligible for instant utility rebates that lower the effective price
Where it falls short
- A Nest-vs-ecobee comparison thread reported the humidity sensor reading off by 10–15% against a Fluke meter
- r/HomeKit users cite scene and automation bugs when running more than one unit
- Some r/ecobee owners reported the unit failing to hold settings reliably
- Premium price is hard to justify for buyers who only want basic scheduling
