Logitech Harmony Hub The Logitech Harmony Hub Vera plugin allows Vera3 and VeraLite home automation controllers to manage and control a Logitech Harmony Hub/Link. The plug-in consists of a C++ executable based on the HarmonyHubControl software found on SourceForge.com, cross-compiled for the Vera3/VeraLite, as well as the necessary XML and Luup files required for the Vera UI.
