@mario64 It does not work as a repeater, it registers via Domoticz as a node with a child ID of 255 (Internal effectively) under Setup/Hardware/Nodes, sometimes listed as a Repeater.
It baffled me originally as I have no repeaters nor a need for them, but that is what Domoticz does. Since you can activate which child sensors are active under Domoticz, you can simply ignore them anyway.
Not sure if you have figured this out yet without reading back to confirm it, but until you send a sensor reading after presentation the device will not show up within Domoticz and remains in the background....
