I had better luck adding the GE/Jasco Enbrighten outlets by adding by brand GE->Outlet->GE Z-Wave. If there are other wired Z-Wave devices in your network, you shouldn’t have to get the hub closer since the other devices will act as repeaters. For my newer Z-Wave Plus outlets, I had good luck scanning the QR code.
Also, the driver posted earlier is for dimmers and motion dimmers. You’ll want this one for outlets [ST Edge] Driver for GE/Jasco/Honeywell Z-Wave Switches, Dimmers, Fans, Outlets, and Plug-Ins.
