Thanks John
I have now put XB24-ZB, ZigBee Router API, 23A7 radio firmware on the dongle as per your instructions in your first post on this page FAQ: Mapping your ZigBee network with Digi's XCTU and followed the other numbered instructions.
I went into console mode in XCTU and it now looks like this (see below pic) so i guess i’ve done something but im not sure what!
I think the top left icon is the xstick, the red icon is smartthings and the far right green icon is the wall plug. I assume that the two purple icons are smartthings sensors.
So what next? How do i get my wall plug to act as an extender? I havent done anything directly to it yet. Wont the fact that i’ve made the xstick a router rather than coordinator now prohibit me from programming the wall plug as needed? (it cant see the plug as a child now when i do a scan )
