What others asked before buying

Can I control all my Mysas in the same app?

Yes. Control everything from the one app. Manage baseboard heating, ductless mini-splits, central HVAC, and electric in-floor heating in one place.Set unique schedules for each thermostat, and in the future group them all together for seamless control.

Do thermostats go bad on electric baseboard heaters?

They can, especially older mechanical thermostats. Internal bimetal strips can degrade over time, leading to temperature swings, while dust buildup or loose wire connections can cause unresponsive controls or safety hazards.

It might be time to upgrade to an electric baseboard heater thermostat if you notice any of these signs, and your search ends here at Mysa. Not only does this solve your problems, but it gives you precise digital temperature control from anywhere!

Does it require Wi-Fi?

Yes. Mysa needs a 2.4 GHz WiFi connection to enable remote control, voice commands, smart home integration, and app-based features like energy reports . Without WiFi, the thermostat still regulates temperature using manual controls on the device itself, but you lose all smart functionality. Make sure your WiFi signal reaches the thermostat location before installation

Does Mysa have a microphone or speaker?

No. It's a thermostat, not a listening device. We believe those experiences are best left to a smart home speaker that's likely updated more often than your thermostat.

Does Mysa sell my data?

No. We sell thermostats. That's how we make money. Full stop.

How do I know if my baseboard heater thermostat is bad?

They can fail. Here are some signs your baseboard heater thermostat might be failing:

  • Your heater doesn’t respond when you adjust the temperature on the thermostat.
  • Your room feels too hot or too cold, indicating calibration drift.
  • You hear clicking, but your heater doesn’t heat up; this could indicate a burnt-out heater element.
  • The faceplate of your old mechanical thermostat feels too hot to the touch. (Smart thermostats like Mysa may feel slightly warm during normal operation — this is normal.)

It might be time to upgrade to our smart thermostat for electric baseboard heaters. You’ll love being able to control the heat in every room from anywhere, and our precise calibration ensures reliable, comfortable performance.

What is Mysa?

Smart thermostats built for every system in your home. We help you save energy and maintain a comfortable home. With its user-friendly app, you can control your heating or cooling systems from anywhere.

What temperature should baseboard heat be set at?

It’s entirely up to you and your comfort level. Most homeowners using Mysa keep baseboard heaters around 68–72°F (20–22°C) when they’re home, and lower the temperature to 60–65°F (16–18°C) while sleeping or away. Mysa’s electric baseboard thermostat lets you create custom heating schedules and uses geolocation to automatically adjust the heat based on your lifestyle, maximizing comfort and energy savings.
