Sync fails with MyHarmony desktop software:

If the Harmony remote isn't being detected by the computer and therefore the MyHarmony desktop software isn't allowing you to sync, then please review: Harmony isn't being detected by the computer.

  • Harmony IR based remotes can be placed into a sync recovery mode by removing one of the batteries and holding down the All Off button on the remote as you reinsert the battery. A message indicating safe mode will appear on the screen and you may try to sync again.
  • Harmony hub‑based products are capable of a factory reset which will clear all settings from your remote and may help to resolve sync errors. All account information from the MyHarmony desktop software will be retained in the Harmony cloud and will not be lost.
Sync button colors
  • The Sync button is grey when there are no changes to sync.
  • The Sync button is yellow when there are changes to sync, but the remote is not connected to your computer.
  • The Sync button is blue when there are changes to sync and the remote is connected.

If Harmony is detected, but sync fails at a certain percentage:

  • Disconnect Harmony from your computer connect it again to an alternate USB port.
  • Sign out of your account on the MyHarmony desktop software, sign back in and try again.
    Having trouble closing Harmony software?
  • If your Harmony remote has removable batteries, ensure they are installed correctly.
  • Use a different computer to log into your account, then snyc.
  • If you're still having issues, please see our user forum to search for answers or post questions.

Sync fails with the Harmony mobile app:

Reboot Harmony Hub by disconnecting the power cord, then plugging it back in and waiting 30 seconds for it to turn on again. The light on the front of the hub should be green once complete. Once complete, force the Harmony app to close on your mobile device and then relaunch it.

Forcing the Harmony app to close:

  • iOS devices: Double press the home button, press and hold on the Harmony app icon then select the close icon.
  • Android devices: Press the recent apps button then swipe the Harmony app icon off of the screen. If you don't have a recent apps button:
    1. Navigate to Settings > Applications.
    2. Depending on your firmware version, you may need to select Application manager.
    3. Scroll down and tap Harmony, followed by FORCE STOP.

If you continue to experience issues when attempting to sync using a mobile device, then we recommend connecting harmony via USB and attempting the desktop steps.
