Pros & Cons
ecobee Smart Thermostat Essential
Pros
- +Cheapest route into ecobee's SmartSensor ecosystem — 32 occupancy-sensing sensors will pair to a $140 thermostat
- +Wi-Fi 6 and Bluetooth LE 5.4 make it the most modern radio stack in this comparison
- +3-year warranty at $139.99, which beats Google's 1-year on the similarly priced Nest Thermostat
- +Full colour touchscreen rather than the monochrome or button-driven UI at this price from Resideo and Copeland
Cons
- −The Power Extender Kit that comes free with both bigger ecobees costs $24.99 here, so a C-wire-less home pays $165 not $140
- −The radar occupancy sensor is gone — the Essential cannot tell whether you are in the room without a $50 SmartSensor
- −No accessory terminal at all: no humidifier, dehumidifier or ventilator control
- −Heat pump support stops at 2H/1C, so cold-climate multi-stage systems are out
- −Launched at $129.99 in March 2025 and now lists at $139.99 — an eight percent rise in the first year
ecobee Smart Thermostat Enhanced (EB-STATE6L-01)
Pros
- +Same screen, same radar occupancy sensor and the same in-the-box Power Extender Kit as the $259.99 Premium, for $60 less
- +Handles heat pump 2H/2C with aux, which is more staging than the Nest Thermostat, X2S, Sensi Lite or Amazon can manage
- +Still takes 32 occupancy-sensing SmartSensors if you add them later
- +3-year warranty
Cons
- −No SmartSensor in the box — buy one and the price gap to the Premium closes to almost nothing
- −No air quality monitor, no speaker and no built-in Alexa or Siri voice
- −One auxiliary heat stage instead of the Premium's two, which matters on cold-climate heat pumps
- −No Matter on ecobee's spec list, so Matter-only smart home setups are out
- −Only one 1-wire accessory circuit, so a humidifier and a ventilator cannot both be driven
