These observations are derived from recorded catalog data and have not all been independently verified. Confirm details with the manufacturer before purchasing.
Manufacturer-source decision brief · Checked 2026-10-04
US manufacturer pages checked for included SmartSensors and HVAC accessory support. This is a specification-based decision brief, not a hands-on test. Other table fields retain their individual evidence labels.
Premium includes a separate SmartSensor. Our interpretation: if you want a temperature reading away from the thermostat, count that included accessory when comparing the complete setup. It does not mean every room has a sensor.
ecobee Premium: US specifications and box contents ↗Enhanced works with SmartSensors sold separately. Our interpretation: it remains an option if you already own compatible sensors or do not need an additional room sensor. Compare equivalent accessories rather than the thermostat alone.
ecobee Enhanced: US specifications and SmartSensor support ↗Premium lists support for one 1-wire or one 2-wire HVAC accessory. Our interpretation: confirm your equipment and wiring with ecobee before treating either model as a replacement; a feature comparison is not an installation approval.
