Help adding new device/os!

I have been trying to add a new device to LibreNMS but i fail on the polling of sensors.
So i would like to request some help on this.
Below is all data i have gathered so far.

Discovery: Untitled - LibreNMS
Poller: Untitled - LibreNMS
Snmpbulkwalk: Untitled - LibreNMS

Kind Regards
