Org.openhab.binding.openenergymonitor

Hi, I’d like to use this Add-on but I can’t understand if RFM69Pi module must be in Openhab Raspberry-Pi.

I’d like to access OpenEnergyMonitor data, but I have it running in another Raspberry-Pi. Is not possible to access OpenEnergyMonitor database directly?

Thanx any help to understand how it works.
