Score: 82/100
Mysa Smart Thermostat
Score: 74/100Rankings

The Emerson Sensi Touch provides a color LCD touchscreen, geofencing, and wide smart-home compatibility while being ENERGY STAR certified. Mandatory C-wire power and lack of 5 GHz Wi-Fi or battery backup constrain some installations. It fits homeowners wanting reliable scheduling and voice-assistant control without premium pricing.

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.
