Doremi DCP2000 digital cinema server

I’m fairly new to libreNMS. I’m trying to add a few devices related to digital cinema world, in particular playback servers and projectors, but I’m having little success.
For instance, here I have collected the relevant informations about a player:
Discovery: Doremi DCP2000 Discovery - LibreNMS
Poller: Doremi DCP2000 Poller - LibreNMS
Bulk: Doremi DCP2000 snmpbulkwalk - LibreNMS

Any hint is wellcomed!
