Network Wide Inclusion (NWI) is a technology that allows Z-NET to add or delete devices to/from your Z-Wave network at long ranges. This greatly simplifies the process of setting up most networks. However, NWI will only work with the newest Z-Wave devices, those with v4.5x or 6.5x Z-Wave firmware (ZDK) installed. Adding/deleting older devices will require Z-NET and the device to be positioned within a few feet of each other. In these cases, the built-in WiFi adapter allows Z-NET to be easily repositioned. Any device marked with a Z-Wave+ logo supports NWI. Most devices available today are based on at least the 4.5x ZDK and will support NWI even though they are not marked with a Z-Wave + logo.
