Not sure if this helps, but I just moved from UI5 to UI7, fresh install (3 other bridged hubs as well...fun). I use Imperihome to interface with the Vera system. All was well until a call into Tech Support. The next morning, I tried Imperihome, it just kept loading and loading, all my android devices were the same. It looks like my Main Controller had been put into SECURE MY VERA mode (under Users and Account Info/Unit Settings). Once I unchecked that option, all is well. Imperihome is working like a champ on and off network.
