Afterglow

Your Harmony still works.
Now set it up again.

Logitech shut the Harmony service down in 2025, and with it every way to change what your remote does. Afterglow builds the configuration on your own computer and writes it to the remote over USB. No account, no subscription.

Every button, your way

Choose what each button does in every activity, down to the last one on the remote, and which device it controls.

“Watch a Movie” turns on the projector, receiver and player in the right order, switches each to the right input, and sends every button where it belongs.

Bring your setup along

Import the backup you read from your remote and your devices and activities are back, ready to change. Codes can also be learned off the original remotes.
