I just checked again, for my One, 900, and 880 accounts, and there is no Reset Remote option.  Software 7.7 has been old for a very long time going on 2 years, and is still the only version available there is no Reset Remote option available, it would be nice if there was.  The 5 options for my Harmony One under Remote settings are Manage Remotes, Display Settings, Set Up a SlideShow, Select a Theme, and Replace Remote
