ecobee Smart Thermostat Enhanced
Score: 86/100Rankings
The ecobee Smart Thermostat Enhanced delivers up to 26% energy savings, geofencing and radar occupancy detection with a vibrant 4-inch touchscreen. It lacks air-quality monitoring and multi-zone support, which may limit advanced users. Ideal for single-zone homeowners seeking strong energy-saving features and wide smart-home integration.
The Amazon Smart Thermostat is an ENERGY STAR-certified, Alexa-focused thermostat with auto-learning temperature control and a compact touch-sensitive display. Its main trade-offs are the mandatory C-wire and limited 2.4 GHz Wi-Fi with no built-in voice mic. Ideal for Alexa/Ring users seeking an affordable, easy-install solution.
