RPi 3 with Nexa WMR 252 and RF Transmitter on PI

Hi,

Ive got a Pi 3 and some RF Transmitter for the Pi.
Connected as shown in this image: link

Then i have a Nexa WMR 252 wich the object is to be able to control.
The thing is, i didnt buy a nexa remote. So figuring out the codes to send to the wmr is proovin tricky for a noob such as myself.

The nexa has a learning system in place. So i figure i dont really need to buy a remote.
If this is incorrect please let me know.

And if im right in thinking so. How do i go about making this work?
Im sure i need a proper nooby howto to get this to work.
Would really appreciate any help you could offer me.
