Mysa V2 vs Mini-Split Key Specs
System Compatibility
The Mysa V2 Smart Baseboard Thermostat is built specifically for electric baseboard, fan-forced, convector, and radiant ceiling heaters. It handles line voltage systems up to 1,900W at 120V or 3,800W at 240V. It does not work with 24V furnaces or central heat pumps. The Mysa Smart Thermostat for Mini-Split AC is designed exclusively for mini-split heat pumps and air conditioning units. It replaces the original remote control. You must choose the model that matches your heating and cooling hardware. Using the wrong unit will not function correctly with your existing system type.
Wiring Requirement
The Mysa V2 requires four wires to operate. It needs a neutral wire or a second live wire to function. It will not run on a standard two-wire mechanical thermostat setup without new wiring installed by an electrician. The Mysa Smart Thermostat for Mini-Split AC does not list specific wiring wire counts in its published data. It functions as a smart controller that replaces your existing remote. This means it connects to the mini-split’s internal communication lines rather than high-voltage home wiring. If you have existing baseboard wiring, the V2 needs upgrades. The mini-split unit uses a different connection method entirely.
Display Type
The Mysa V2 features a built-in touchscreen display. You can adjust temperatures and view settings directly on the device without needing your phone. The Mysa Smart Thermostat for Mini-Split AC does not list a display type in its specifications. It relies on the app for interface control. If you prefer to change settings physically on the wall, the V2 offers that capability. The mini-split model assumes you will use the mobile app for adjustments. This is a key difference for users who want immediate local control without unlocking a device.
Sensor Support
The Mysa V2 includes a built-in humidity sensor. This allows the thermostat to monitor moisture levels in the room alongside temperature. You can set alerts for unusual humidity changes. The Mysa Smart Thermostat for Mini-Split AC does not list sensor support in its published specifications. It focuses on temperature control and remote functionality. If tracking humidity is important for your comfort or home maintenance, the V2 provides that data directly. The mini-split model lacks this specific sensor feature in the provided data.
Connectivity
Both devices connect to 2.4 GHz Wi-Fi networks. The Mysa V2 requires a 2.4 GHz connection and does not mention 5 GHz support. The Mysa Smart Thermostat for Mini-Split AC also uses 2.4 GHz Wi-Fi but explicitly states it works with combined 2.4 and 5 GHz networks and mesh Wi-Fi networks. This gives the mini-split model slightly broader compatibility with modern router setups. Both offer app control and voice integration. The mini-split unit may handle complex network environments better due to its stated mesh and dual-band support.
Build and Size
The Mysa V2 measures 3.5 inches in length, 1.57 inches in width, and 4.85 inches in height. It weighs 1.12 pounds. The Mysa Smart Thermostat for Mini-Split AC measures 2.87 inches in length, 5.59 inches in width, and 6.65 inches in height. It weighs 9.88 ounces. The V2 is taller and heavier, likely due to its internal components and touchscreen. The mini-split unit is wider and lighter, designed to replace a wall-mounted remote. The physical footprint differs significantly, so check your wall space or existing bracket compatibility before ordering either unit.
