If the only issue with using the XW6000ES codes is the power button then this is user error as there is no Power Button on the remote. The Off button on the remote turns off an entire Activity and has no function on individual devices. If you really need an off button for an individual device you need to program one of the buttons below the screen on the remote to do it or add it to favourites. Or if you are not going to use Activities buy the U1 or U2.
