I think that "driver.version.internal: 0.38" puts your version a little later than that (after NUT 2.7.1), but this is more for my own curiosity at the moment.

Especially given all of the new topologies with NAS systems, we could use a few more diagrams to clarify this.

> However, I do have a follow on question. The only entry in upsd.users on the NAS has 'upsmon master'. Can I run upsmon on my desktop as a slave, or do I need to create another user in upsd.users on the NAS with 'upsmon slave'?

I would consider this an implementation detail (though not likely to change): the "upsmon master" permissions are a superset of the "upsmon slave" permissions. You should be able to set up your desktop as a slave using the existing upsd.users.
