OpenWRT version 23.05.0-rc3 is, for starters, not supported anymore by
the OpenWRT project, and is old.
The current version is OpenWRT 23.05.05
The reason you are likely getting an old version of NUT when you load
the nut package is because you are using an old version of openwrt.
Your team needs to sysupdate your 4G LTE Wifi router
You also, in my opinion, need to seriously reconsider running NUT on an
openwrt router. The reason why is that NUT generates logfiles and
writes to the filesystem.
The flash chips that are used on routers are not designed like a USB
flash stick where they are intended to have a read/write filesystem on
them. They have no bad block management with NAND flash chips. That is
provided by a UBI layer. You can read about that here:
[OpenWrt Wiki] The OpenWrt Flash Layout
<https://openwrt.org/docs/techref/flash.layout>
SOME of the NAND devices that OpenWRT has been ported to, DO have
complete UBI support, others don't. You did not say what model of
router you are running - but unless you have researched it and are
completely sure that it has a fully functional bad block management, you
can easily cause problems over time attempting to run programs on an
OpenWRT router.
In general it's safest to run READ ONLY programs on openwrt. For
example, the snmpd server. Programs that WRITE to the filesystem on the
OpenWRT router should be avoided.
There's a reason we use hard drives on servers.

Dear NUT Developers,
A very good morning to you and hope that you are in the best of health
and spirits.
For an upcoming UPS Project, our team has been testing Powercom’s
Cleanline T-1500 UPS model whose photo has been attached with this
e-mail. Our team has been testing this UPS with one of our 4G LTE WiFi
router models on which Network UPS Tools (NUT) Version 2.8.0-3 has
been installed. BUT during the testing our team observed multiple
instances of error message *"Data for UPS [pcmusb] is stale - check
driver"* being randomly reported by our 4G LTE WiFi router. Here is
the SUMMARY of the issue below for clear understanding purposes.
* NUT Version 2.8.0-3 was installed on our 4G LTE WiFi router by our
team.
* Also our 4G LTE WiFi router had Linux Kernel Version 5.15.127,
OpenWRT Distribution release “23.05.0-rc3” and OpenWRT
Distribution Revision “r23389-5deed175a5” installed on it.
* Powercom’s Cleanline T-1500 UPS was connected with our 4G LTE WiFi
router via USB to USB Cable Connection (i.e. USB Port on router
side and USB Port on UPS side)
Now when NUT installed on our 4G LTE WiFi router model unit tried to
poll and fetch values of different UPS parameters from Powercom’s
Cleanline T-1500 UPS model
after both UPS and router had been running for sometime (i.e. for
random period of time):
o router started reporting the error message *“Data for UPS
[pcmusb] is stale - check driver”*
o after that router could not get UPS’s status any more unless
we restart the NUT service
o and the router started reporting the error message “Data for
UPS [pcmusb] is stale - check driver” after running for
sometime again
Note: *[pcmusb]* represents the *name or identifier* assigned to the
UPS instance within the NUT (Network UPS Tools) configuration
* Our team tried to increase value of NUT’s timers such as
“pollinterval”, “pollfreq”, “maxage” but still the issue could not
get solved or fixed
* Kindly NOTE that our team tested the above with both the NUT
Drivers i.e. blazer_usb and nutdrv_qx. But the same error message
mentioned above was observed.
* Also kindly NOTE that our team also tried to test with NUT Driver
“usbhid-ups” but it is seems that this particular Driver is not
supported by Powercom’s Cleanline T-1500 UPS model whose photo has
been attached with this e-mail.
* Currently our team is not 100% sure about the exact root cause.
Our team need to know the following from NUT Developers.
* Which the is correct NUT Driver that our team need to use on the
4G LTE WiFi router so that it can communicate smoothly and
successfully with Powercom’s Cleanline T-1500 UPS model whose
photo has been attached with this e-mail?
* Which specific parameters within the default Configuration
Settings file of NUT Version 2.8.0-3 on our 4G LTE WiFi router
need to be tweaked / changed so that our 4G LTE WiFi router model
can communicate with the Powercom’s Cleanline T-1500 UPS model
smoothly and successfully?
* Which specific parameters within the default ups.conf / upsd.conf
file on our 4G LTE WiFi router needs to be tweaked / changed so
that our 4G LTE WiFi router model can communicate with the
Powercom’s Cleanline T-1500 UPS model smoothly and successfully?
Also I am hereby attaching the Log Files with the Log Messages
reported on our 4G LTE WiFi router model. The 1st Log file contains
Log Messages during testing with NUT Driver “blazer_usb” while the 2nd
Log file contains Log Messages during testing with NUT Driver
“nutdrv_qx”. You will observe the ERROR Message *“Data for UPS
[pcmusb] is stale - check driver”* within both these attached Log Files.
Awaiting your swift response back.
Thanking you,
Yours sincerely,
