Ecobee buying guide
Check for a C-wire before ordering. Ecobee ships a free Power Extender Kit for 2-wire systems. For whole-home temperature balancing, the SmartSensor accessory is worth adding on multi-story homes. Renters can often install an ecobee without a professional and take it when they move. Prefer a different brand? Our Honeywell thermostat guide covers every current Honeywell model.
