I have this working, so I'll try to help, by comparing what you've said
with my working setup.

That's ok. Same as mine.

I have "root root" instead of "nobody asterisk". I don't know whether that
is significant or not. It may be. Try it.

Whether the MIB is loaded or not doesn't matter, if you are specifying
an OID by number. It's just for translation, a bit like DNS for IP addrs.

I get:
SNMPv2-SMI::enterprises.22736.1.1.1.0 = STRING: "11.18.0"
SNMPv2-SMI::enterprises.22736.1.1.2.0 = Gauge32: 111800

The other thing to check is further up in /etc/snmp/snmpd.conf. See what
views are defined, and the access groups to which they have been assigned,
as they specify what part(s) of the OID tree will be served.
I have this:
## incl/excl subtree mask
view all included .1 80
## context sec.model sec.level prefix read write notif
access MyROGroup "" any noauth exact all none none
access MyRWGroup "" any noauth exact all all all
which makes everything under .1 visible. Not sure if that is the default or not.
