Unknown type OIDs that are not routers, switches, printers or access point

Unknown type OIDs that are not routers, switches, printers or access point

How do we handle assets scanned that report invalid OIDs that are not of the type  routers, switches, printers or access point?
 
We have networked devices such as Environment Monitors, UPC's, Power Strips, etc that are network devices that can communicate via SNMP, but are not of the types available.
 
I am unable to identify the device by OID correction, and without that, scans continually fail on that device.
 
I am on 8.1 build 8127
