I've just fired up a new ISY99i IR PRO (updated to latest firmware, 2.6.7), and I'm trying to get my configuration loaded into it. I did an "add device" for a 2414U PLC (which knows about all my other devices), selected "Add devices found in links...", and it spun for a while, seeming to find a few devices, then quit after about 30%. No devices other than the PLC show up in the main window. If I try to re-run the add device, nothing happens. Am I doing something wrong? Am I going to have to manually enter all my devices?
