Buyer's guide

How does a smart AC controller work?

It sits near your mini-split, window, or portable AC and sends the same infrared signals as its remote, adding app control, schedules, and temperature-based automation.

Will it work with my AC?

If your AC came with an infrared remote that shows the temperature, almost certainly. Check the maker's compatibility list for your brand.

Can it replace a thermostat?

For mini-splits, yes: the controller reads the room temperature and adjusts the AC, which is often more accurate than the sensor inside the unit.
