Some of our older remotes, such as Harmony One, 880, 900, 1000, and 1100, use the Logitech Harmony Remote Software v7.x to add devices and get everything set up (see list). You can also use the software to make configuration changes in the future. Harmony One, 600, 650 and 700 remote users may upgrade to MyHarmony if they previously used remote software 7.x to set up their remote.
