I'll ask the obvious which is wouldn't it be easier to write a driver
for NUT that would exec python code (or other scripting languages) that
talked to the UPS?
Seems to me that nowadays the hack/reverse engineer/disassembly crowd
who loves breaking into stuff is really big into python and having
something like this might make it easier to prototype drivers for
oddball UPSes... - it could also help with writing screen-scrapers (my
understanding is the SMC1000I has a network port and I'm betting it
provides some rudimentary webinterface)

Does anyone feel up to the challenge?
There's some research and python code to interact with MicroLink-only
serial APC models, waiting for a port into NUT...

Hi there,
as you know APC is still manufacturing MicroLink-only UPSs. I have
purchased a APC SMC1000I and just found out that it could only be used
as a generic USB-HID UPS with NUT right now. And unfortunately the
SMC-series is not capable of ModBus so there are still APC devices out
there which can only use MicroLink for a full operation.
So I think it would be great if MicroLink-UPSs could be supported
directly by NUT at least through a serial connection. That's why I'd
like to raise this /feature request/ here.
For testing purposes I have created a custom serial cable with this
pinout <https://pinoutguide.com/UPS/apc_0625_cable_pinout.shtml> and
used the following Python tool for checking the MicroLink
communication with my unit:
https://github.com/klaasdc/apcups-serial-test
I was able to get information about my unit and even set the battery
installation date through MicroLink in a Python shell (with the help
of some sample code
<https://github.com/klaasdc/apcups-serial-test/issues/1>). So it seems
like the protocol description is there, it's just written in Python
and needs to be ported to C. Unfortunately I am only familiar with
Python and not with C :(
