Ecobee Smart Thermostat Premium Review
By Rendict Staff · Updated August 1, 2026 · 1 min read
The Ecobee Smart Thermostat Premium is a Wi-Fi thermostat that pairs a built-in Alexa speaker with a bundled room sensor for even, multi-room heating and cooling control.
Installation
The Premium works with most systems that have a C-wire; homes without one get Ecobee's included power extender kit rather than a required separate purchase.
Living with it day to day
The bundled room sensor is the standout feature for multi-room homes — it lets the thermostat average or prioritize temperature from a room other than where the thermostat itself is mounted, which single-sensor competitors like the base Nest can't do without an add-on purchase.
Verdict
For Alexa households with more than one room that runs hot or cold, the bundled sensor and built-in voice assistant justify the higher price over the Nest or Amazon Smart Thermostat.
Frequently asked questions
It works best with one, but ships with a power extender kit for HVAC systems without a dedicated C-wire.
