Mysa for Mini-Splits Overview

Mysa for Mini-Splits is a smart IR controller that replaces your handheld remote. Control your mini-split heat pump, window AC, or portable air conditioner from anywhere using the Mysa app or your voice.

How It Works

Unlike wired thermostats, Mysa for Mini-Splits controls your unit using infrared (IR) signals — the same technology as your remote. During setup, Mysa learns your remote's IR codes and takes over control.

Key point: Mysa requires direct line of sight to your indoor unit's IR receiver.

What It Controls

Mysa works with most mini-split heat pumps, window air conditioners, and portable AC units that use an IR remote with an LCD display.

Supported modes (depending on your unit):

Heat
Cool
Auto
Dry
Fan Only
Swing

Fan speeds: Typically 3-5 speeds depending on your unit.
