First, a HUGE thanks !

To answer your questions, (and I should replete, for those coming after :-)  - this is a vigor embo 650 UPS device) )

(I have some success, - but there is still some issue - see below, I'll go through whats working first)

When I boot my iMac, with the device connected, I get:
echo show  'State:/IOKit/PowerSources/UPS0' | scutil
<dictionary> {
  Is Charging : TRUE
  Is Present : TRUE
  Max Capacity : 100
  Name : STD UPS MON V1.0
  Power Source ID : 0
  Power Source State : AC Power
  Transport Type : USB
  Voltage : 130

The state remains unchanged if you pull out the power on the UPS, and it is working from batter - HENCE the need to use NUT …

Next, if I unplug, and re-plug the USB cable, I then do not have any keys in the scutil…. e.g.:
echo list 'State:/IOKit/.*' | scutil
  subKey [0] = State:/IOKit/Power/CPUPower
  subKey [1] = State:/IOKit/PowerManagement/CurrentSettings
  subKey [2] = State:/IOKit/PowerManagement/SystemLoad
  subKey [3] = State:/IOKit/PowerManagement/SystemLoad/Detailed
  subKey [4] = State:/IOKit/SystemPowerCapabilities

At this point, if I follow the instructions given in the link you provided below (THANKS), things begin to show some hint of life:

for completeness, and to help anybody else:

> more /System/Library/Extensions/NUTDummy.kext/Contents/Info.plist 

<?xml version="1.0" encoding="UTF-8"?>

<plist version="1.0">
    <string>Dummy UPS Driver</string>
        <key>Uninterruptible Power Supply</key>

Now, the following commands work:
> sudo /opt/local/bin/upsdrvctl start
> sudo /opt/local/bin/upsd
> upsc zigor

(Given I have set up /opt/local/etc/ups.conf).

HOWEVER :-(((((
If you want a second, and run upsc zigor again, you get
Error: Data stale

In the kernel.log I get:
Sep 24 12:11:16 Marks-iMac kernel[0]: USBF:     1122.116        [0xffffff801a1ed400] The IOUSBFamily is having trouble enumerating a USB device that has been plugged in.  It will keep retrying.  (Port 1 of Hub at 0xfd100000)

Sep 24 12:11:23 Marks-iMac kernel[0]: USBMSC Identifier (non-unique): 000000009833 0x5ac 0x8403 0x9833

If I stop and re-start the drivers - everything works again, ONCE.

I _think_ related to this - it's not exactly ideal to have to unplug, and re-plug the USB cable each time I restart my machine  - so I'm GUESSING I have an issue still with the NUTDummy mechanism, but I'm not sure I know what it could be… 

Any ideas?
