• USP monitoring and shutdown software for Cyberpower 550VA?

    From George Garth@none@nowhere.com to alt.os.linux.ubuntu on Wed Mar 18 07:37:06 2026
    From Newsgroup: alt.os.linux.ubuntu

    Looking for Ubuntu 22.04 recommendations for monitoring and shutdown
    software for Cyberpower 550VA.

    As my PC is dual boot at start up (either Win 10 or Ubuntu), I've always
    had the Cyberpower software in Win, but I seldom use Win. Not sure what
    to use for Ubuntu.

    Thank you!

    I don't know if this will work for you, but there is a powerstatd showing
    in the tar.gz version. I would presume the USB interfaces have some
    amount of "custom" to them, and the best interfaces on computers
    follow "USB Class" standards, to allow a more generic package to
    work with more things.

    But at least that demonstrates to me, there is some approach to running UPS shutdown.

    CyberPower has software for Linux, get the deb version for Ubuntu. I use
    it on all my Ubuntu systems and at the library I manage

    <https://www.cyberpower.com/global/en/product/sku/powerpanel_for_linux#downloads>

    Note that it is command line only. Been meaning to make a python GUI
    overlay for Windows refugees but haven't gotten around to it. Maybe this year...

    Been trying it out today, but can't seem to get it to work. I wish
    there was a Ubuntu GUI because I hate command line. I'm going to
    uninstall the deb soon and just let everything alone. I've been
    considering replacing the lead acid battery with one of the lithium
    phosphate ones. Not sure if it's a direct replacement though.

    This last time the battery went defunct, I thought the UPS was at fault because it kept cycling on and off even if nothing was plugged in. The replacement battery seems to have solved the issue, but I'd like to get something lasting longer than 3 years which is why I was looking at the lithiums.

    I hear you, especially since the configuration file is a bit confusing.
    What most people want is to set the UPS to run on battery WITHOUT THE
    DANG ALARM until the battery gets low and then shut the system down
    gracefully. Unfortunately that is not the default configuration on
    Linux. It shuts the system down as soon as there is a power failure, NOT
    what you want. Here is how to fix it, step by step:

    1) install the deb (use the terminal because your need it to check
    things (sorry):

    2) start terminal:
    CTRL + ALT + T

    3) cd where the deb file is, assuming in Downloads
    cd Downloads

    4) install it:
    sudo dpkg -i CyberPower_PPL_Linux+64bit+(deb)_v1.4.1.deb

    5) Check that it is successfully running
    systemctl status pwrstatd --no-pager

    you are wanting to see " Active: active (running)"

    6) Now let's fix the setup, first back up the config, just in case ;)
    sudo cp /etc/pwrstatd.conf /etc/pwrstatd.conf.backup

    7) Now edit the file:
    sudo nano /etc/pwrstatd.conf

    a) find "powerfail-shutdown" setting and change from "yes" to "no", you
    do not want the system to power off immediately when a power fails

    powerfail-shutdown = no

    b) find "lowbatt-threshold" the default is 35%, adjust to how long you
    want to run on battery when the battery falls to before the system
    powers off

    lowbatt-threshold = 35

    c) find the "lowbatt-shutdown" setting and confirm it is "yes". You do
    want the system to power off on this condition

    lowbatt-shutdown = yes

    d) find "enable-alarm" setting and change from "yes" to "no", we don't
    want the damn thing beeping while on battery. You will know you have a
    power failure

    enable-alarm = no

    e) save the file and exit:
    CTRL + X

    8) now restart service and check status

    sudo systemctl restart pwrstatd && systemctl status pwrstatd --no-pager

    You now should be good to go. while in the terminal you can do some things

    Check the status with:
    sudo pwrstat -status

    You should see your UPS model and current status

    Also a good time to check the battery with the test:
    sudo pwrstat -test

    Wait a couple of minutes and check the status again. If your system
    shuts down immediately when stating the test and the status check said
    the batteries were full then your batteries are dead and need to be
    replaced

    Ok, thanks a bunch! Finally able to get some software response.
    Initially I tried just clicking on the deb and installed from the
    software center, but wasn't getting any of the above.

    I recently had to replace the power supply so it's about double what the
    UPS is supposed to handle. After about 2 min, batt had dropped to 35%,
    so will have to be sure and shut down asap if power fails.

    Thanks again for your help. I will print out the instructions and keep
    them handy nearby.

    The power supply won't matter it is the power load your system draws,
    most of the library workstations load is only about 6-10% load

    Properties:
    Model Name................... CP1500PFCLCDa
    Firmware Number.............. CR01802CBH11
    Rating Voltage............... 120 V
    Rating Power................. 1000 Watt(1500 VA)

    Current UPS status:
    State........................ Normal
    Power Supply by.............. Utility Power
    Utility Voltage.............. 122 V
    Output Voltage............... 122 V
    Battery Capacity............. 100 %
    Remaining Runtime............ 92 min.
    Load......................... 60 Watt(6 %)
    Line Interaction............. None
    Test Result.................. Passed at 2022/08/06 22:46:44
    Last Power Event............. Blackout at 2026/03/16
    19:19:09 for 12 sec.

    But this new Window 11 sucker I just build is 26% Load for 35 mins
    runtime. If your battery dropped to 35% in just 2 minutes and you load
    is 30% or less then you need new batteries. I find MightyMax one on eBay
    or Amazon are good. Just bought a pair of 12V 9Ah SLAs for $45

    Youtube has vids on how to swap out batteries.


    Thanks again for your help.  I will print out the instructions and keep
    them handy nearby.

    I'll run the test again later and check the load, but it's going to be a
    good bit more than 30% I think.

    Just a couple of issues. I noticed upon rebooting when checking status,
    only the UPS properties were shown and current UPS status was
    disconnected. Only when I removed and plugged in the USB cable from the
    UPS did current UPS status show info.

    I also don't see "load" and "line interaction" parameters like in yours
    above as they are missing.

    I think it is because you are using a more basic model the ol' brick
    type like this if I am not mistaken:

    Whereas I use the tower versions with more features like this:

    The brick one appears to be an SPS which is not line interactive.
    The voluminous marketing text tries to "chew around the edges and
    deceive the buyer". When it says "simulated sine wave", it could
    be a real multi-point sine wave, but at the price charged it
    could be a traditional "stepped square wave" drive.

    Since it is not line interactive and it does not adjust the
    voltage when not on battery, there is nothing to monitor from
    that perspective.

    I use a Kill-O-Watt meter for monitoring just one computer here,
    and that tells me what my line voltage is.

    I had a UPS for a lot of years, but the replacement batteries
    now don't last very long, and the UPS is just retired.

    My UPS was an SPS (Standby Power Supply) with no features too.
    That type, is ice cold to the touch, and only when on batteries,
    is there a chance for the inverter inside to heat anything.
    When an SPS starts to get warm, it means the 12V battery has some
    cells which are shorted internally. And the heat can mean it is
    time to change the battery. The battery thing is quite a scam.
    Another application of lead acid battery chemistry, nets the people
    running the scam, $11 billion per year.

    The "best" UPS is used by IT people, it is double conversion and
    AC-DC-AC at all times and has zero switchover time. Those have
    a fan to cool the internal circuitry.

    There are at least five different kinds of UPS, from a features
    perspective, and one of the companies has a brochure that attempts
    to explain what they do.

    My substation has a step-changer, and the step-changer is computer
    controlled. For example, at peak load times, it steps up one step,
    and later, steps down one step. I was talking to the operator on
    the phone one day, and attempted to get the thing adjusted. But
    when the operator makes a "momentary change" like that, it is not
    entered into the computer schedule, and the computer schedule
    doesn't even measure what it is doing. It does the same step pattern
    each day. Which is better than nothing.

    The power went out at 3AM one day, power company staff absolutely
    hate it, when an attempt to bring up power, trips the breaker
    again (because they can be standing right next to it, and the
    noise can blow you right out of your shoes). So they couldn't
    get it to start. But somebody on their phone support list knew
    what they were doing, they set the step-changer to min, then
    when the staff brought the substation up, it held, and they
    stepped back up to nominal. I guess you could say, I have
    some "Rather creaky-grade-rural-power network". The previous
    city I lived in, was nothing like this. Gridded and rock solid.

    I think it is because you are using a more basic model the ol' brick
    type like this if I am not mistaken:

    <https://i5.walmartimages.com/seo/Cyberpower-550Va-330W-Ups-Green_e95a84da-d643-40fe-b644-48d4ed740ae2.1c7f9fc4685f001a9b7b44520fee9b0e.jpeg?odnHeight=2000&odnWidth=2000&odnBg=FFFFFF>

    Whereas I use the tower versions with more features like this:

    <https://i5.walmartimages.com/seo/CyberPower-CP1500PFCLCD-1500VA-1000W-Black-Battery-Backup-UPS-System-with-12-Outlets-5-ft-Cord_a4925c46-2cbc-4e6f-ab1e-00f5e816ed2d.6d50bdcac788ce6143c486cf0dc8fddb.jpeg?odnHeight=573&odnWidth=573&odnBg=FFFFFF>



    The brick one appears to be an SPS which is not line interactive.
    The voluminous marketing text tries to "chew around the edges and
    deceive the buyer". When it says "simulated sine wave", it could
    be a real multi-point sine wave, but at the price charged it
    could be a traditional "stepped square wave" drive.

    Since it is not line interactive and it does not adjust the
    voltage when not on battery, there is nothing to monitor from
    that perspective.

    I use a Kill-O-Watt meter for monitoring just one computer here,
    and that tells me what my line voltage is.

    I had a UPS for a lot of years, but the replacement batteries
    now don't last very long, and the UPS is just retired.

    My UPS was an SPS (Standby Power Supply) with no features too.
    That type, is ice cold to the touch, and only when on batteries,
    is there a chance for the inverter inside to heat anything.
    When an SPS starts to get warm, it means the 12V battery has some
    cells which are shorted internally. And the heat can mean it is
    time to change the battery. The battery thing is quite a scam.
    Another application of lead acid battery chemistry, nets the people
    running the scam, $11 billion per year.

    The "best" UPS is used by IT people, it is double conversion and
    AC-DC-AC at all times and has zero switchover time. Those have
    a fan to cool the internal circuitry.

    There are at least five different kinds of UPS, from a features
    perspective, and one of the companies has a brochure that attempts
    to explain what they do.

    So, I'm curious, if your power does go off without a UPS, what happens
    to your PC, just instantly turns off? The only reason I finally
    replaced the battery in this unit was because there were three or four
    times this year where the power flickered and the PC immediately shut
    off. One or two of those times, a boot up revealed some changes to one
    of the hard drives. I was concerned about possible damage with too many
    more power flickers.

    I don't like how short of life the batteries have either, which was why
    I was looking into a drop in Li ion replacement, but my research shows
    it isn't that simple without circuit changes. I use Li ion 12 V/ 10 Ahr batteries for all sorts of purposes and love their longevity.

    Correct. I figured that was probably why. And that is a standby for a
    700 W internal power supply, which was why I was mentioning that it was
    a little insufficient for the task. However, if the battery lasts a
    couple of years and can power off in a minute, I'll be happy. I just
    don't have extra funds right now for an upgrade.

    For SSDs, the USN journal playback at startup, provides some
    cleanup on NTFS (on Windows). EXT4 also has a journal, and
    some cleanup should work there too. I don't know all the details
    of what fsck does when it spots trouble like that. There is
    no point having a journal, if you aren't using it.

    Dropping power on an SSD, places a big dependency on the firmware.
    Consumer SSDs don't have a Supercap and advanced-power-fail. They
    rely on the firmware keeping immaculate map files from virtual
    to physical sector. I don't purposely go around hitting the
    power button with SSDs, but a power fail will do it. The RESET
    button is better for the SSD, as the SSD on SATA interface
    have no reset pin, so the SSD does not receive a reset. An
    NVMe is quite likely to be different.

    The LFP 4S-4P battery, the marketing says "you can just pretend it
    is lead acid". Well, not really. LFP are better at taking abuse,
    but using one in a UPS would be a "constant abuse" situation
    and I doubt that is good for their lifespan. You won't find a lot
    of crazy-people testing that for you either. My UPS does trickle-charge
    at 13.5V and that represents "constant charging without relief"
    for a 4S-4P LFP. The safety half of me says "don't do that".
    If you do manage to light LFP on fire, it probably burns.
    I don't think it is necessarily a self-extinguishing mess.

    We need "someone with a big back yard" to test this :-)

    Out of curiosity, I wanted to see the price for a commercially made unit
    of similar wattage to mine:

    https://tinyurl.com/ycxcjr92

    Interesting. About double the cost of my dinosaur that I bought at
    least a decade ago.

    If I had the extra funds available, I'd purchase and try one. Maybe
    hint around for a Christmas or birthday gift might net one.

    That really what you want. It is the flickering power failure that kills
    a pc, especially a spinning hard drive.

    Quite true. In fact, the last battery actually protected against those
    one second flickers long after its supposed expiration date. Power
    flickers and <5 sec outages are generally what I get here. Maybe 3-4x a
    year. Over time, damage is done if nothing buffers against the surges.
