Mysa Smart Thermostat
Score: 74/100Rankings
Mysa's Smart Thermostat V2 is a line-voltage Wi-Fi thermostat designed for electric baseboard and similar heaters, delivering up to 26% energy savings with precise temperature and humidity alerts. Its compatibility is limited to electric heating systems and it lacks battery backup and Bluetooth, restricting broader use cases. Perfect for homeowners upgrading electric heating with smart controls and zoning capabilities.
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.
