Digital Home ControlControl over 270,000 home theater devices from a Harmony remote or your smartphone. Patented Smart State Technology™ remembers your devices’ power and input settings and automatically adjusts them based on what you want to do. The right remote for you depends on your home theater setup. If your entertainment system is an open cabinet, any Harmony universal remote will give you a great experience. Closed-cabinet entertainment systems work best with one of our hidden-device remote controls. The online setup software does the hard work for you, programming your remote for your setup. If you have questions, help is available when you need it.
