Emonpi data on Openhab

Hi, first of all I’m new to Openhab . I saw that there is an Openenergy monitor binding in openhab. I have a separate emonpi (bought couple of years ago-older version). what data can be intergrated to the openhab and how (simple steps preferred ) is the data coming directly from the emonpi to the openhab or is the data feed through emoncms
site

thanks in advance
