[Nut-upsuser] 24V DC ATX PSU with limited UPS functionality over USB

Hello Developers and *,

I am working on a "24V DC ATX PSU" for Photopholtaik Systems which can
have input voltages from 18V to 27.7 Volt and is entirely modular,
which mean, you can select the desired module/s (up to 6) from ATX
(96/144/240/300W), P4 (144W), SATA (82/305W) and Device (34/68/136W)

And last not least, I want to build a "PowerWhatch" module which should
be connected from the PSU to an internal USB port of the mainboard.

Currently I do not know, whether I should use Maxims 1-Wire chips like
the DS2450 which has four AD-Converter or a I²C/SMBus solution.  Both
will work with the DS80C411 Microcontroller...

Now the question to you:

Since I do not want to reinvent the wheel, I like to use existing
programs where I think, NUT is the perfect solution...  The problem is,
HOW I have to deliver the data to it or how must I provide it?

The "PowerWhatch" module picks only the Voltage and Amperes and
Temperature from each of the 11 modules... and maybe it will store them
for a while in a 8-16 kByte NV-RAM or something like this...

If you have ideas or suggestions, please let me know.

Greetings and Nice Day
