ups's Introduction

Mini-Box.com UPS Status and Configuration Tool

Mini-Box.com produces several high quality intelligent Uninterruptible Power Supplies. This is a tool to report status information and configure these UPS models.

Supported models

OpenUPS: 6-30V Intelligent Uninterruptible Power Supply
OpenUPS2: 11-24V Intelligent DC-DC Uninterruptible Power Supply using LiFePO4 or 13-24V using Li-Ion (see manual)
NUC-UPS: 6-38V Intelligent Automotive grade Uninterruptible Power Supply
DCDC-USB: Intelligent buck-boost DC-DC converter with USB interface
DCDC-USB-200: Intelligent buck-boost DC-DC converter with USB interface

Warning

The flash storage on these devices have limited write cycles (should be considered < 100.000) so it's not advisable to keep writing the configuration periodically on a timer.

Documentation

These devices allow advanced configuration which can be quite complex. It's recommended to read the documentation using the links below before attempting to configure these UPSes.

Install from prebuilt binary

$ sudo snap install openups --edge

(Don't have snapd installed?)

Install from source

$ git clone https://github.com/mini-box/ups.git
$ cd ups
$ cmake .
$ sudo make install

Using

For all commands below replace device name with the name of the device you want to control eg: openups, openups2, nucups

Show help, supported devices and supported commands per device:
```
 $ openups -h
```
Show status and configuration:
```
  $ sudo openups -t <device name>
```
Show only status
```
  $ sudo openups -t <device name> -s
```
Export current configuration variables from device to file
```
  $ sudo openups -t <device name> -o <file name>
```
Import configuration from file to device. Warning: it will restart your UPS and in certain cases the device connected to it !
```
  $ sudo openups -t <device name> -i <file name>
```
For configuration variables you can add -c switch on command line to output a detailed description for each variable. Example: 6. UPS_INIT_DELAY_TOUT: 1 # [s] Initial delay before starting the UPS. Default is 1 sec.
Some devices accept commands to set for example the output voltage:
```
  $ sudo openups -t dcdcusb -e set_vout:11.5 -s
```

Troubleshooting

There might be issues with apparmor/SELinux that won't allow access to raw usb devices. For the snap binary this can be solved by:

    $ sudo snap connect openups:raw-usb

Network UPS Tools

For remote management or shutdown configuration it's also possible to use Network UPS Tools. Open UPS and Open UPS 2 are already integrated in latest version so installation should be straight forward on different Linux flavors. For more details on custom installations and configuration for our UPS products on Network UPS Tools see these links:

Why there are no protective validators for settings/options?
Why there is no option or command for "factory reset"
Is this device reliable and safe to operate with Li-Ion at all?

The NUC-UPS has the
Firmware Version: (null):
VerMajor: 1
VerMinor: 3

Why i need to write settings:
The device didn't charge the cells and was stucking on "State machine CHG: END ||| State machine UPS: LPWR(or similar)"
even worse it discharged the cells.
So i found the setting "VIN_MIN_STARTUP=20000"(is it set from factory?) and decided to switsch to 11.5V...
And now I have broken device?

read error when trying to pull RTE and capacity

I am using openups with firmware 1.9 and the configuration set is in the attached file.

While trying to run the following code inside GetStatus() method of object HIDOpenups:
" ret = sendMessage(OPENUPS_CLOCK_OUT, 0);
usleep(1000);
recvMessage(recv);
parseMessage(recv);
"
I get the following error:
"
hid_interrupt_read failed with return code -110
Read error [0xc0]: -110
"
it reads the capacity and the RTE but puts to 0 all the other values.
If I comment this part of code I get all the values with correct values except for the RTE and capacity and the error is not present.
Furthermore I saw that the windows interface doesn't have this problem.

settings.txt

Flash write cycles

Is it possible to permanently change the charging current without wearing out the flash?
What would that command look like and would this also be possible over I2C bus?

add libusb-dev install to readme

sudo apt-get install libusb-dev

otherwise you will get:

ups/src/lib/usbhid.h:4:10: fatal error: usb.h: No such file or directory

openups only retrieves 3 out of 6 cells

Given everything I do is Linux based, I am pleased to have this tool. However, I recently upgraded three OpenUPS installations from AGM batteries to use 6 LFP cells each. The Windows configurator shows the 6 cells correctly but Linux openups only shows 3 of them. Other provided information looks accurate:

Configuring V-In current limit

Hey, I am using the NUC-UPS in an application where I am powering a server from a weak/unpredictable power source.

I have a power supply that maxes out at ~12v 2.2A and then is disabled until a power cycle if that is exceeded. I'm trying to find a way to limit the maximum current draw of the V-In on the ups, but not sure if there is a software-based configuration.

For example, I have another power supply that gets to ~12v 1.3A and then runs in CC mode and drops voltage, but the 12v 1.3A rating is too low for this application, as it causes the server to run on battery far too often. Is the NUC-UPS capable of setting a current limit for the input source?

OpenUPS Voltage Regulation problem

Good Day,

I have configured my OPENUPS with the below parameters.

12V 5A input power
12V LIFEPO4 (8000mah) Battery

When i have the power on i get a voltage of 11.8v, then when i switch off power my volt reading goes from 9v to 13.58v in one second which causes my device to switch off so something is wrong. Does anyone have a working config file of this that i could use.

Anyone else experiencing this issue?

Im beginning to think that the issue is caused due to a faulty buck/boost converter.

Thank you.

Communicating with NUCUPS, but voltages and currents reported as zero

Hi @nicupavel and @mini-box,
Fantastic to have a Linux tool to talk with the mini-box UPSs - good job! I have built and tested. It looks to be communicating with the UPS fine, but has a few issues reading some of the data, such as voltage and current (see logs below). This is possibly connected to the hid_interrupt_read failed with return code -110 error reported but the usb library.
Have tried running with root user and also made sure to stop NUT and processes that might have locked access to the USB interface. (in fact this cleared the error interface 0 already claimed by driver "usbfs", attempting to detach it I saw initially.)
Is there anything you can suggest we try to correct this?
Thank you for your help.
Cheers,
Adam

UPS not starting after shutdown condition

Hi!

I've very strange behaviour, if running on battery and one cell downs 3300mV the ups sends a graceful shutdown to the motherboard but it shutdown the nuc-ups itself too. After recovery the VIN the nuc-ups is powered off and it doesnt charge (because is off) the only way to start it again is connecting a external powered usb 5v to the micro-usb port, S1 & P9 does nothing.

I tried to change config1b3 and config1b4 but this parameters are useless if the ups is off.

I can't find anything in the parameters to change that behaviour. Anyone knows how to start de nuc-ups without connecting a powered 5v cable to it?

Problem OpenUPS Driver Set Vout

Hello everyone,
I'm integrating OpenUPS into one of my Windows Forms applications (C#) on Windows.
I can display getUPSVIN, getUPSOutputPower, or getUPSVOut without any problems.

What I would like to do is to be able to persistently modify the output voltage, but it doesn't seem like it's possible to do that with the OpenUPSLib DLL.
What would be the most optimal solution? Is there a way to modify this output voltage in another way? Maybe via command line with the .exe and a parameter?
It would be great if someone had the solution!

OpenUPS does not report the battery capacity or the RTE

I used the library with the OpenUPS but it does not report the battery capacity or the RTE, and after checking the code I found that the part responsible for getting these values is blocked with the following comment:
//TODO This breaks further communication with device. Needs more investigation.

Is there any way to make it work and return the battery capacity?

configuration from the config file gets saved to device

Additional information

configuration is saved correctly using Windows GUI tool which has its own quirks like no possibility to import from csv or no possibility to select settings.ini file location and one hast to export to csv first which sets location where settings.ini is taken from)
openups tool reports error about not being able to write to config file (not sure why it even attempts to do so). complete output of an unsuccessful write attempt:
