Questions to check before buying	A published compatibility list is a manufacturer statement, not a tested installation guarantee; the manufacturer compatibility checker and the actual wiring decide.

Energy savings figures on the manufacturer pages are marketing claims and are not recorded as facts. Not compatible with the first-generation ecobee Room Sensor; SmartSensor is the supported remote sensor.
