TUSTIN, Calif. — The Sofia AI Thermostat from Nuve Controls is a smart-home-enabled Wi-Fi control, compatible with the Google Alexa system, that’s designed to support a wide range of residential and commercial HVAC systems while helping contractors stay connected with homeowners long after installation. The thermostat is compatible with most HVAC systems that use a 24 Vac control circuit, including furnaces, boilers, heat pumps, traditional a/c equipment, and dual-fuel systems. It also supports humidifiers, dehumidifiers, and ventilators, as well as installations using a C-wire adapter because a common wire is unavailable.
