ups3's Issues

How should the four LED should light up (on)

Hi, excuse me. I'm finally trying out my UPS3 but seems to not turning on the 4 main lights (which is supposed to be for Battery percentage). Also, is there any way to display my battery percentage on my taskbar from Raspberry Pi OS?

Thanks. Otherwise, after installation, it says it is not charging (to charging it, do I must to connect my supply cable to the UPS module right?)

The smartups.py service floods the smartups.log file

It logs almost every second (pls. see below) and the log file grows unnecessarily by about 6 MB in 24 hours and thus unnecessarily increases the memory card wear in RPi.

I suggest logging only when changing any of the parameters and at least once every 1 hour, if at all.

Sample from /var/log/smartups.log file:

Getting the UPS3 software running

This UPS3 github repo was updated in June of 2020 with the purpose of "making it compatible with python3". Then in May of 2021 they apparently blasted the older Python2 files back on top of the Python3 versions. You will need to add parentheses on all of the print statements in the three .py files.

I set this up on a Pi Zero W with Bullseye Lite. I needed to install both smbus and pip3 as a prerequisites before running install.sh, as neither are in the Lite Bullseye build apparently. The install failed without these prior installs:

sudo apt-get install python3-pip
sudo apt-get install python3-smbus

The smartups service was failing with the following, per systemctl status smartups

Dec 18 17:28:35 RPi3 systemd[1]: smartups.service: Scheduled restart job, restart counter is at 5.

journalctl -e -u smartups showed:

The sudo password prompt was a clue. I had previously set sudo to require a password. After undoing the sudo password requirement setting the smartups service starts properly.

A few additional notes

  • The service runs as user pi, and thus requires use of sudo to issue a power down halt.
  • status.py stops the smartups service, does its thing, then restarts the service. Thus, running status.py must be done with sudo.
  • Python3 complains about status.py line 209 if service_status is 0: is should be ==.
  • smartups.py logs to /var/log/smartups every second. That's a lot of pounding on the SD card for a long term.

For my applications I'm thinking of implementing a service that can be provide status info to a calling app, rather than the provided scheme of killing the service, reading the registers directly, and restarting the service. Thus, a user app need not be run with sudo. More study and research TBD.

Install with errors, service fails to load

I determined a couple of problems. It was tested with Raspbian Buster (27th May 2020) on RPi 4B:

When executing the install script, it reports:
dpkg-query: no packages found matching scons

After going through the menu items of the install script and enabling the service, it fails to start.
This is, what systemctl reports (sorry for the truncated lines):
pi@raspberrypi:~/ups3 $ sudo systemctl status smartups.service

When starting the smartups.py manually, this happens:
pi@raspberrypi:~/ups3 $ /usr/bin/sudo /usr/bin/python3 /usr/local/bin/smartups.py
Traceback (most recent call last):
File "/usr/local/bin/smartups.py", line 12, in
from neopixel import *
File "/usr/local/bin/neopixel.py", line 5, in
import _rpi_ws281x as ws
ModuleNotFoundError: No module named '_rpi_ws281x'

Hoping you can fix it soon.

The install.sh script does not install the rpi-ws281x Python library due to a server outage

The following code is used in the install.sh script:
SOFT = $ (pip search rpi-ws281x | grep "INSTALLED")
which, however, is currently failing due to a failure on the part of PyPI's search backends, pls. see the error listing below.

I suggest using this code instead.
SOFT = $ (pip list | grep "rpi-ws281x")
Or better yet, replace pip call with pip3 everywhere, which solves incorrect include when running other scripts using python3, especially in smartups.service.

	SOFT = $ (pip3 list | grep "rpi-ws281x")
	if [ -z "$SOFT" ]; then
		pip3 install rpi-ws281x
