Mysa has carved out a smart home niche by focusing on high-voltage heating. The Smart Thermostat LITE brings that specialized control to 120V and 240V electric baseboard heaters, a category often left behind by mainstream smart thermostats. It’s a direct solution for a specific, frustrating problem.

Installation is a clear advantage for renters or DIYers. It’s designed to replace a standard line-voltage thermostat without needing a C-wire, using your existing wall wires for power. Once connected, the app guides you through setup for Apple HomeKit, Google Assistant, or Alexa. Geofencing and auto-scheduling then work quietly in the background, turning heat down when you leave and warming the room before you return. The physical dial and display are satisfyingly solid, offering local control that doesn’t feel like an afterthought.

This is a focused tool. It excels at managing a single, powerful heater type with reliable smart features. It won’t control a central HVAC system, and that’s the point. For baseboard or convector heat, it delivers precise, automated comfort where most other smart thermostats simply can’t go.
