Nut upsuser - Nov 2020 - NUT with Geekworm x728 UPS Hat on RPi?

I searched the forum from the website and didn’t get any hits, so I thought I’d
ask here.

I have an RPi 4B running Home Assistant. It has the NUT integration, and I have
a Geekworm X728 UPS Hat installed.

It has an I2C interface for reading data.

I was wondering if NUT supports that?

Not in its current form.  The installation script seems to be generating two 
Python2 scripts which very approximately play the role of a driver attached to 
NUT's upsd.  To get this to work with NUT means writing a C language X728
driver
based on the Python2 scripts.  Whether it's possible to write a upsd driver
in
Python3 is an open question.

Health warning. Python2 is now well past its end-of-life. No support, not even 
security updates. It's urgent for X728 to migrate to Python3.

unless you use a linux distribution which maintains its packages for a 
long time ( like 10 years ) in which case at least backports are used to 
close any security holes that are discovered and relevant.

While the init scripts are python 2, the UPS is straight I2C reads, using Python
3 to read and decode the I2C would be easy enough, if I knew how NUT needed to
see things. Imma NUT Newbie 😬

Looking back on this thread, I think we got carried away by Python.  To go back 
to your question: the answer is no, but if you are interested in developing a 
driver for the X728, there is a driver developer guide at 
https://networkupstools.org/docs/developer-guide.chunked/ar01s04.html

Roger

Also for i2c specifically, you can look at examples in asem and recently
pijuice drivers.

Hope this helps,
Jim Klimov
