Mysa Smart Thermostat for Ductless Mini-Split Heat Pumps

Yes, you can control your preferred setpoint temperature from the thermostat’s faceplate. Adjusting the temperature manually overrides your Schedule until the next set point change and doesn’t interfere with app settings.

Yes. The free Mysa app gives you complete temperature control from your phone. Full control means adjusting your thermostat from bed, work, or vacation.

Yes! Ductless mini split heat pumps, window AC units, and portable AC units are all electric systems controlled by a remote using IR (infrared) signals instead of a thermostat wired into a wall. Mysa uses IR signals to pair with your unit and replace your remote, functioning as a thermostat that helps regulate heating and cooling. The convenience of IR smart thermostat control means no more searching for the remote or worrying about whether you turned off the mini‑split or AC; simply change or monitor your home’s heating and cooling settings from the Mysa smartphone app.

Most mini‑split systems don’t have a traditional thermostat like central HVAC systems do. They’re controlled by a handheld remote that sends infrared (IR) signals directly to the unit. That’s how each indoor head in your home acts as its own “zone.” But it also means each zone needs its own thermostat or remote to control temperature settings. You can replace those remotes entirely with the Mysa mini‑split thermostat. Each one connects to a specific mini‑split head, unlocking simple, wall‑mounted or tabletop control and full app access to manage every zone from one place.

Mysa integrates seamlessly with Amazon Alexa, Google Assistant, and Apple HomeKit. After connecting, you can use simple voice commands like “Hey Alexa, set the bedroom to 72 degrees” or “Hey Google, turn off the living room AC,” making managing home comfort easy when your hands are full or you don’t want to reach for the phone.

 Plug the Mysa for AC & Mini-Splits into a power outlet and place it on a tabletop or mount it on a wall where it has a clear, direct line of sight to your AC unit. Then, use the Mysa app and your AC's original remote to complete the infrared (IR) pairing process.

Programmable thermostats rely on manual input that often fails. Research shows 73% of owners never use the scheduling features because they are too complicated. Mysa removes this human error. Geofencing detects when you leave to lower the heat automatically, while smart schedules save 3-5 hours of runtime daily while you sleep. You save 15-26% on heating costs without touching the dial.

Mysa helps reduce your electricity bill by optimizing when and how your heating or cooling runs. Using features like custom scheduling, geofencing and Eco‑Mode, Mysa ensures your mini-split only runs when you need it and at the most efficient settings. Detailed energy insights in the app show how much energy each zone uses so you can make informed adjustments to save more. Many users see savings of up to 20% without sacrificing comfort.

Mini-splits rely on IR communication to adjust heating or cooling settings — the same technology your remote uses. Mysa’s Smart Thermostat for Mini-Split Heat Pumps & AC works by learning those IR signals and taking over as your new smart controller. Once Mysa takes over, you can control temperature, mode, fan speed, and scheduling from the Mysa app or your favorite smart-home assistant. No need for wiring changes or system modifications. It simply replaces your remote and gives you smarter, easier control.

Customers typically save 10-26% on heating & cooling costs. Heating and cooling is the single largest energy expense in North American homes. Natural Resources Canada identifies heating as 61% of total energy use, while the U.S. Department of Energy confirms a simple daily temperature setback cuts annual bills by 10%. Whether you are cutting down a $2,000 annual energy bill or tackling a harsh Canadian winter, Mysa ensures you never pay to heat an empty house.

Absolutely! The Mysa thermostat is designed to optimize energy usage, helping you save on heating costs. With features like scheduling and remote control, you can manage your energy consumption effectively. Enjoy a cozy home while being environmentally friendly.

Mysa’s Mini‑Split Thermostat replicates the functions of your existing remote, including any humidity‑control settings your unit supports. While the thermostat itself doesn’t measure humidity, it can transmit humidity-related commands from the remote to your mini‑split if available. You can adjust humidity through the app when supported by your AC unit.

Mysa for AC and Mini-Splits replaces most LCD remotes for ductless mini-split heat pumps and window/portable AC units. It works with many popular brands like Mitsubishi, Fujitsu, LG, and Frigidaire, as well as General Electric for portable ACs and other brands such as DeLonghi, Frigidaire, and Danby. If your brand isn’t listed, our supported brands list is always growing.
