Specifications side by side

Mysa Smart Thermostats Compared

You can choose from six Mysa models based on your wiring and system type. The Mysa Lite suits four-wire electric baseboard setups, while the Mysa V2 adds a touchscreen display for the same use case. If you have a central HVAC system with a C-wire, the Mysa Smart Thermostat for Heating & Cooling offers Energy Star certification. For older 2-wire retrofits, the Mysa Central Smart Thermostat with C-Wire Adapter provides a practical solution without extra hardware costs.

Radiant floor and mini-split owners have dedicated options too. The Mysa Smart Thermostat for Electric In-Floor Heating supports 120-240V systems and works with Apple HomeKit or Alexa. The Mysa Smart Thermostat for Mini-Split AC and Heat Pumps adds Google Home compatibility for air conditioner owners. All units use Wi-Fi connectivity and allow programmable scheduling. You get full app control without recurring subscription fees for any of these picks.

Where Mysa Fits Your Home

Mysa targets specific heating and cooling infrastructure rather than offering a universal replacement. You can choose from models designed for electric baseboards, central HVAC, in-floor radiant systems, or mini-split heat pumps. The lineup spans from compact units like the Lite to larger displays such as the V2. All listed models share Wi-Fi connectivity and programmable schedules. You will not find a single thermostat that covers every system type. You must match the device to your existing wiring and hardware. The range is practical but strictly divided by system compatibility.

How to choose the right one

1. Check system compatibility

   Match the thermostat to your heating infrastructure. The Mysa Lite and V2 are designed specifically for electric baseboard heaters with four-wire wiring. If you have a central HVAC system, you need a model that supports 24V power, such as the central HVAC thermostat. For electric in-floor heating, select the dedicated in-floor model. Mini-split owners require the specific mini-split thermostat. Using the wrong unit for your system type can cause installation failures or equipment damage. Verify your system type before purchasing.

2. Verify smart home integration

   Ensure the thermostat works with your existing ecosystem. The Mysa Lite and in-floor models support both Alexa and Apple HomeKit. The mini-split thermostat adds Google Home to that list. The V2 model supports Alexa. If you rely on Apple HomeKit for automation, avoid the V2 if it lacks that specific compatibility in your region. Check the attributes for each model to confirm support. Smart home integration allows you to control temperature via voice commands or routines without a subscription.

3. Assess wiring requirements

   Wiring determines which thermostat you can install. The central HVAC model requires a C-wire for power. If your system lacks this, you may need the bundle with a C-wire adapter for retrofits. Electric baseboard models like the Lite and V2 connect directly to four-wire setups. In-floor models handle 120-240V systems. Verify your existing wiring configuration before buying. Incorrect wiring can prevent the device from powering on or functioning correctly. Check your thermostat box or hire an electrician if unsure.

4. Consider display preferences

   Choose a display type that suits your needs. The Mysa V2 features a touchscreen interface, allowing for direct local adjustments. The Lite and other models rely primarily on app control. If you prefer physical interaction, the V2 is the clear choice. If you only adjust settings remotely, any model works. The display type affects how you interact with the device daily. Consider whether you want to see temperature changes instantly on the wall or via your phone.

5. Look for certifications

   Check for energy efficiency certifications. The central HVAC thermostat is Energy Star Certified. This indicates it meets specific efficiency guidelines set by the EPA. Other models do not list this certification in their published data. If energy savings are a priority, the certified model may offer better long-term performance. Certification helps verify that the device meets industry standards for efficiency. It does not guarantee lower bills but suggests optimized operation.
