ecobee Smart Thermostat Premium
Score: 86/100Rankings

Ecobee Smart Thermostat Premium combines a 4-inch high-resolution touchscreen with built-in air-quality monitoring, smoke detection, and SmartSensor room control. It demands a C-wire (or Power Extender Kit) and carries a higher price point. It excels for users desiring premium features and robust performance.

The Honeywell Home RTH9600WF is an ENERGY STAR-certified smart thermostat featuring a vibrant color touchscreen and extensive smart-home integration. Its requirement for a dedicated C-wire and incompatibility with certain heating systems limit installation flexibility. Ideal for homeowners with compatible 24 VAC systems seeking advanced display and remote control.
