Amazon Smart Thermostat
Score: 73/100Rankings
The Honeywell Home RTH6580WF is an affordable Wi-Fi thermostat that offers solid basic scheduling and broad system compatibility. Its main drawbacks are the lack of geofencing, auto-learning, and the need for a C-wire. It is best suited for budget-conscious homeowners with standard 24 V HVAC systems who want voice-assistant control.
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.
