My portable controller wasn't on the screen at all before, as far as I can recall. I just found the icon for it (an RZCPG) way off the screen. This has bit me before with new devices in ThinkEssentials. They appear on the floor plan, but off screen (_WAY_ off screen on most cases) and no scroll bars appear. I have to make the thinkessentials window very big to find them.
So my portable controller now appears and with an icon I hadn't seen before.
My switches (RZI10s, etc.) just appear as dimmable light bulbs, as before.
My 4-zone controller isn't actually in my network right now, mainly because it was so miserable to configure it.
So maybe I am seeing the new icons.
