Mysa Smart Thermostat for Central HVAC review

Mysa built its name on baseboard and mini-split thermostats, and its central HVAC model brings the same app to furnaces, central air and heat pumps. Mysa says it works with 95% of standard 24V systems, including conventional systems with 2 stages of heat and cool, heat pumps with auxiliary heat, dual-fuel setups and boilers, and that it installs in 20 to 25 minutes. It is ENERGY STAR certified, and Mysa puts savings at 15 to 26% on heating and cooling. Matter certification means it connects directly to Apple Home, Alexa and Google Home with no hub. The app covers schedules, geofencing, monthly energy reports and shared access, and you can run Mysa baseboard or mini-split thermostats in the same account. It needs a C wire, Wi-Fi is 2.4 GHz only, and it cannot control humidifiers or ventilators. Room sensor support is not available yet. Coverage runs 5 years.
