Mysa Smart Thermostat
Score: 74/100Rankings
The Ecobee3 Lite offers a budget-friendly 3.5-inch touchscreen, built-in sensors and broad HomeKit, Alexa and Google Assistant support. Its reliance on a C-wire or power extender kit and modest display resolution may deter users seeking higher-end visuals. Best suited for cost-conscious owners of 24 V HVAC systems who value multi-room sensing.
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.
