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.

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 long do underfloor heating thermostats last?

10 years or more, depending on use and environmental conditions. But older thermostats lose accuracy over time, leading to temperature swings/inefficiency. Even if yours still "works," it could be worth upgrading to our electric floor heating thermostat.

Is Mysa safe for hardwood, laminate, or luxury vinyl flooring?

Yes. Select your floor type in the app during setup to activate Smart Limit Protection. Mysa automatically caps floor temperature at 30°C (86°F) (or your manufacturer's limit) to prevent warping or fading.

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.

Will Mysa allow my bathroom tile to get hot enough?

Yes. Select Tile or Stone mode to unlock higher thermal limits. Mysa allows your floor system to reach 40°C (104°F), ensuring tiles feel warm even on cold mornings.

    Excellent choice for In-floor heating

    Being a happy Mysa product user for a long time (I am using Mysa Smart Baseboard Thermostats for many years), I decided to try another product, this time for in-floor heating. I had a good experience working with other smart thermostats for in-floor heating from SunTouch and Meross, and I wanted to compare and select one to use for my Master Bathroom. And my final decision was to use the Mysa one. The Mysa thermostat is easy to connect; cables that come out of the wall are relatively short, and it’s a challenge to connect them directly to a smart thermostat. The Mysa one comes with cables built-in, and connecting it is a very very simple thing. I also liked how easy it was to connect it to the home network, and to the Mysa APP. The application itself is easy to use, and easy to trust. I do not remember even one time when the application was not working well and I was not able to control my devices. The only one thing I wish to have when it comes to the Mysa Smart In-Floor thermostat is to be able to see the outdoor temperature (the way SunTouch does). I like my Mysa smart thermostat, and recommend it to everyone.
