I didn’t do my homework before purchasing a Klipsch Flexus Core setup.  After setting it up, I tried to add it to the MyHarmony software. However I found there was no result for any of the Flexus core products.  When I tried to manually program the remote codes, I found that the remote is not IR but Bluetooth!

However, there are 4 steps to get a Flexus core setup working with a Harmony remote:

1. Enable IR on the soundbar by setting it to Installer modeFrom the following page:
   https://support.klipsch.com/hc/en-us/articles/29405500891924-Flexus-100-200-Operating-modes

   Pressing and holding Source and Vol + buttons on the bar and then short press of the Bass button on the remote.
   Press the Vol + button on the remote to toggle through all operating modes –

   Consumer Mode (CONSUMER)→ Display Mode (DISPLAY)→ Retail Mode (RETAIL)→ Installer Mode (INSTALLER)→

   Long Press Bass (>1 seconds) to confirm selection.

2. In the MyHarmony software, add a Klipsch Cinema 400
3. Change your Activity settings to use the “Klipsch Amp” as your audio device
4. Sync your hub and basic functionality should now be working!
