Single Stick controller configuration

Hi everyone,
It seems nobody had this same problem or I’m dumb to find the right thread somewhere.

I’ve bought a VRBox with remote control included (the one in the picture attached below)
In my project the controller has to be used to move around the house and open doors.
I’ve tried to set up the input commands for it, but it seems the program doesn’t recognize the controller when i lunch it on mobile.
Then I’ve connected the controller to the PC and as I lunch a VR preview directly on UE4.16, the controllerr acts as a mouse, meanwhile keyboard inputs work properly.
So I’ve concluded the controller is only recognized as a mouse both on mobile and PC.

Do you have any advice about if and how to properly set up this kind of controller?
