Price$259.99$239.99
Release Year20222024
System VoltageLow voltage 24VAC — furnaces, air conditioners, heat pumps, boilers, PTAC and fan coil units. Not for 120/240V line-voltage heatLow voltage 24V only — gas, electric, oil, forced air, heat pump and radiant. Will not run 120/240V baseboard or radiant electric heat
C-Wire RequiredNot in practice. ecobee ships the Power Extender Kit in the box, which synthesises a common wire from R, W, Y and G at the furnace. Direct wiring uses C and Rc if you do have five wiresNot in most homes. Google's patented Power Sharing borrows power from the other wires, and the store page claims roughly 85% system compatibility — but it also states heating-only, cooling-only, zone-controlled and heat pump systems need a Nest Power Connector or a C wire
Adapter / Power Kit IncludedYes — Power Extender Kit included. The same kit is a $24.99 extra on the EssentialNo — the Nest Power Connector is a separate $24.99 accessory, not in the box
Heating & Cooling Stages2H/2C conventional; boilers, PTAC and fan coil units with up to 3 fan speedsUp to 3 stages of heating and cooling, plus fan speed control
Heat Pump & Aux HeatYes — heat pump 2H/2C plus 2 stages of auxiliary heat, the deepest heat-pump staging in this setYes, including auxiliary and emergency heat
Humidifier / Ventilator TerminalsOne 1-wire or one 2-wire accessory on the ACC+/ACC− terminals: humidifier, dehumidifier or HRV/ERV ventilatorHumidifier, dehumidifier and ventilation (HRV/ERV) systems all supported — the widest accessory coverage of the Nest line
Remote SensorsOne SmartSensor in the box; up to 32 pair, over a 915MHz radio at up to 60 ft. Extra sensors are $99.99 for a 2-packOne Nest Temperature Sensor (2nd gen) included; up to 6 more. Google states all generations of the sensor work with this model
Occupancy DetectionRadar occupancy and proximity in the thermostat, and every SmartSensor also detects occupancy over a 140° x 100° field to about 20 ftSoli radar senses presence and proximity at the thermostat itself, plus phone-location Home/Away. The Nest Temperature Sensor reads temperature only — it does not detect occupancy
Matter SupportNot shipping on this model. ecobee's own spec page lists HomeKit, Alexa, Google Assistant, SmartThings and IFTTT and never mentions Matter; third-party write-ups describe a phased rollout, so treat Matter as unconfirmed hereMatter-certified, so it appears in any Matter app including Apple Home. Google does not publish a Thread radio for this model
Voice & Smart Home PlatformsApple HomeKit with Siri, Alexa built in (speaker and microphone), Google Assistant, Samsung SmartThings, IFTTTGoogle Home app (required for setup and control — the standalone Nest app is retired), Amazon Alexa, Apple Home via Matter
Utility Rebates & Demand Responseeco+ Community Energy Savings with 150+ North American utilities. ecobee states events move your temperature 1-4°F for no more than a few hours, a handful of times a year, and you can opt out of any event from the app; some programs pay an enrolment rebate up to $125Rush Hour Rewards, run by Renew Home with your energy provider, plus Nest Renew Energy Shift. Google's own help page says Rush Hour Rewards makes adjustments 'typically up to 4°F' for 3-4 hours during demand events; enrolment is through the Google Home app

Pros & Cons

ecobee Smart Thermostat Premium (EB-STATE6-01)

Pros

  • +The Power Extender Kit is in the box, so the C-wire problem is solved at purchase rather than at $25 extra or a $200 electrician call
  • +Heat pump 2H/2C plus two auxiliary stages beats every other thermostat here on staging depth
  • +SmartSensors detect occupancy as well as temperature — Google's, Honeywell's cheaper models' and Sensi's sensors mostly do not
  • +Built-in speaker and mic make it a working Alexa device, and it doubles as an ecobee Smart Security hub
  • +3-year warranty, a year longer than Google and Resideo

Cons

  • No Matter. ecobee's own spec sheet lists HomeKit, Alexa, Google, SmartThings and IFTTT and nothing else, which is a strange gap on a $260 flagship in 2026
  • $259.99 is the second-highest price here and it went up — ecobee has quietly raised list prices across the range
  • The air-quality monitor produces a score and advice, not a calibrated PM2.5 or VOC reading you can act on
  • Alexa built in means an always-listening mic on your hallway wall, with no hardware mute switch of the kind Echo speakers have
  • Only one accessory circuit — a humidifier and an ERV cannot both be wired at once

Google Nest Learning Thermostat (4th gen)

Pros

  • +The only thermostat here that genuinely writes its own schedule — install it and you can never open the app again
  • +Runs without a C wire in most homes, which no ecobee, Sensi Touch 2, Amazon or Honeywell X-series model here can claim
  • +Three stages plus humidifier, dehumidifier and ventilator terminals — the broadest HVAC coverage in this set alongside the ecobee Premium
  • +Bundles a temperature sensor at a price where the $199.99 ecobee Enhanced bundles none

Cons

  • 'No C wire required' carries a long asterisk: Google's own page lists heating-only, cooling-only, zone-controlled and heat pump systems as needing the $24.99 Nest Power Connector, which covers a large share of US homes
  • The bundled Nest Temperature Sensor is temperature-only — it cannot tell whether a room is occupied, which every ecobee SmartSensor can
  • Setup and control are locked to a Google account and the Google Home app; the old Nest app and Works with Nest are gone
  • Rush Hour Rewards pays you to let the utility push your setpoint by up to about 4°F for three to four hours at a time
  • Highest list price here at $279.99, on a 2-year warranty that both ecobee and Mysa beat
