I would like to chime in and say that I would like to see the capability to add the Almond+ to join an existing z-wave network as a secondary controller. I currently use a ThinkStick with ControlThink software as my primary controller for over 100 z-wave devices (mostly light switches, dimmers, and appliance modules). The ControlThink software provides many features that I do not want to give up such as network optimization, backup/restore, scenes, activities, GUI, etc. I also have a number of Nevo remotes as secondary controllers.
Although it would be nice, I don't really need to import everything from my existing master. However, it simply isn't an option for me redo the entire network with the Almond+ as a master. Until it can join an existing network as a secondary controller it is useless for me for anything z-wave related, which is unfortunate as that is the main reason I purchased it.
