Mysa for Ductless Mini-Split Heat Pumps

Mysa Smart Thermostat for Ductless Mini-Split Heat Pumps makes compatible ductless mini-splits, window air conditioners, and portable AC units smarter without wiring. Instead of relying on a handheld remote, you can control your unit from the Mysa app, build schedules, use geofencing, set comfort ranges, and manage heating or cooling from wherever you are.

Mysa works by learning commands from your unit’s compatible infrared remote and sending IR signals to the indoor unit. It supports common controls like temperature, mode, fan speed, and swing or vane settings when your unit and remote support them. Because it uses infrared, Mysa needs a clear line of sight to the indoor unit’s IR receiver and must stay plugged into power.

Climate+ uses Mysa’s room temperature reading as the comfort reference, helping your mini-split or AC respond to the temperature where people actually spend time — not just at the head unit. Mysa also includes temperature and humidity Smart Alerts, filter cleaning reminders, range limits, on-device controls, and app-based schedules.

It works with Apple HomeKit, Google Home, and Amazon Alexa, has no subscription fees, and includes a 5-year limited warranty.

Key compatibility note: Requires a compatible LCD infrared remote and line of sight to the indoor unit. It does not control freeze protection, Follow Me / I-Feel, Eco, Turbo, Sleep mode, or original remote timer features through Mysa.
