Mysa Smart Thermostat LITE — Line Voltage Baseboard Heater Thermostat 120V/240V | DIY Install, HomeKit, Alexa, Google

Control line voltage heating with ease

Meet the Mysa Smart Thermostat LITE, designed for line voltage electric baseboard heaters, fan-forced heaters, wall heaters, and convectors. It works with 120V–240V systems and supports both single-pole and double-pole configurations, though the unit operates as a single-pole thermostat in typical setups. This is a DIY upgrade that replaces standard thermostats in about 15 minutes using the included video guide.

With Wi‑Fi built in, you can manage temperature from anywhere via the free mobile app. It also integrates with your smart home ecosystem—Apple HomeKit/Siri, Amazon Alexa, and Google Assistant—so you can adjust heat with a quick voice command or automation. There’s no hub to install and no ongoing subscription fees, making smart heating more approachable.
