Frequently asked questions

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.
