Just looked a bit closer (finally had the time to sit down properly, dam kids lol).
My RFXtrx is Device #34.
in the blue bar it is;
GET_LANG(system_error,System error) : Device: 32. Fail to load implementation file D_RFXtrx.xml
GET_LANG(system_error,System error) : Device: 33. Fail to load implementation file D_RFXtrx.xml
So each of the 3 times I attempted to create the device it left this fault, the problem is I cannot find devices #32 and #33 to delete them.
Anyone know how to find and delete hidden devices?
