For test info, look for "ups.test.date" and/or "ups.test.result" in Services / UPS /UPS Status. Are these being reported by the UPS to NUT?

A field like "ups.test.date" could only get populated accurately if the UPS contains an RTC. I've owned a lot of UPSes over the years, and never seen any indication that they have settable clocks. The date fields they do output all look like burned-in-at-the-factory values.

@FrankZappa So, your battery date really does show as 2001/09/25. I believe this means that it was not set at the factory. Looks like the apcupsd widget was reporting the UPS manufacture date rather than the battery install date.

To set the battery date, you can (hopefully) use upsrw.

Use

upsrw -l UPSNAME

to see what variables you can write in the UPS. The variable you are looking for is "battery.date".

Your "ups.test.result" shows that no self test has been run on the UPS. For higher end APC UPSs, this is done by automatic timer. For lower end UPSs, you have to trigger it manually. If you do that, you will have to write the test date yourself--look for variable "ups.test.date" in the upsrw output.

I'm not sure what "battery.date" is really meant to be, but it reads as 2001/09/25 on my APC UPSes too.

See note above. It just means that it wasn't set at factory or at the point of initial install (which requires a UPS that has time capability).

If the UPS doesn't have time capability, then you are responsible for maintaining this field by hand when you initially install and/or change batteries.

If your UPS has a network management card, this would be handled automatically. My current APC is like this.

@FrankZappa Forgot to mention. To run a self-test, would use upscmd. To see a list of commands the UPS will accept, use:

upscmd -l UPSNAME

Most likely, the command will be:

upscmd UPSNAME test.battery.start

On mine, it's not settable period. "upsrw -l" claims to be able to set "battery.mfr.date", but not any other kind of date.

@tgl What brand/model?

FWIW, "ups.mfr.date" is a standard field, but I don't recall ever seeing "battery.mfr.date"

@dennypage Hmmmm, tried to change the battery date but was asked for a password. Huh?

Gertjan · May 20, 2024, 10:30 AM

@FrankZappa

Use the real command line, console or SSH for this - option 8.

Start with :

cat /usr/local/etc/nut/upsd.users

and if all goes well, you see the 'user 'admin, and the password to use.

Yes, writing requires an authorized NUT user. The actual command you will want is:

upsrw -s battery.date=2024/05/20 -u admin -p PASSWORD QNAPUPS

The admin password is automatically generated when you save the NUT configuration. As @Gertjan notes, you can find the current password in /usr/local/etc/nut/upsd.users.

Btw, be sure the date is in the same locale format as upsc outputs.

It's easiest to do this all in an ssh session.

@tgl said in NUT dashboard widget:

[battery.mfr.date]
Battery manufacturing date
Type: STRING
Maximum length: 10
Value: 2022/04/13

This looks like a bug in the usbhid-ups driver. The UPS variable being mapped to battery.mfr.date should have been mapped to battery.date. There appear to be other bugs: on my main (new generation) APC, most of the dates and voltages disappear when switching to the USB interface (vs the SNMP interface). I'll dig into this when I have time.

Btw, if interested you can find a list of all possible variables here. Variable "battery.date" is defined as "Battery installation or last change date." Variable "battery.mfr.date" is defined as "Battery manufacturing date", and was read-only prior to NUT 8.0.

@dennypage said in NUT dashboard widget:

upsrw -s battery.date=2024/05/20 -u admin -p PASSWORD QNAPUPS

I tried it with the password and i get the following error "Unexpected response from upsd: ERR READONLY"

FrankZappa · May 21, 2024, 7:24 AM

@FrankZappa Also noticed there are two entries in the NUT Services/UPS/Status
battery.date 2001/09/25
battery.mfr.date 2021/04/10

The battery.mfr.date is correct. Thats when I bought the APC.
However, the battery.date (and install date on widget) is waaaaaaay off. Can the widget reflect the battery.mfr.date?

I've researched a bit, and it appears that the battery date situation with USB UPSs is a bit messed up. In addition to issues like battery.date vs battery.mfr.date you and @tgl encountered with APC, the CyberPower issues appear even worse.

Truth be told, it probably isn't all NUT's fault as it looks like the manufacturers don't seem to completely agree how the dates should map with USB ids.

I think for the time being I'm going to pull the battery install date out of the status widget, at least for USB UPSs. I think as things currently are it would end up causing too much confusion with folks. I'll revisit it in the future.

Maybe, if the UPS reports both battery.date and battery.mfr.date, you could show the later one?

@tgl I was thinking the same thing, but didn't want to bug Dennypage anymore. Of course, if Dennypage is bored........well?
