NUT UPS does not trigger lowbattery/shutdown - please help!

I set the override_battery_charge_low & override_battery_runtime_low to extreme high values to test if the router proceeds with /usr/sbin/halt and killpower to the UPS.
However when attempting to do that, the values of battery_charge_low & battery_runtime_low get reached but does not trigger low battery or shutdown. As you can see below when executing upsc UPS when on battery, it still says ups.status: OB DISCHRG instead of ups.status: OB LB. Can anyone tell me why this happens?

Im not sure if this has anything to do with /etc/nut/upsmon.conf being incorrectly generated?

Also one more thing.
Even though my setup is in netserver mode and the UPS is reporting correctly, when doing upsdrvctl start, i get:

Network UPS Tools - UPS driver controller 2.7.4
Network UPS Tools - Generic HID driver 0.41 (2.7.4)
USB communication driver 0.33
Can't claim USB device [012c:0002]: No such file or directory
Driver failed to start (exit status=1)

Does this matter?

Would appreciate your helps. thanks

Ok finally solved it myself.

This was a VERY painful setup from start to finish, trying to smell my fingers to figure out what is actually going on because I mostly followed the official wiki guide here.. https://openwrt.org/docs/guide-user/services/ups/software.nut which mislead me completely, since it is not up-to-date. Indeed NUT will drive you NUTS!

Firstly.
The override options are completely wrong in that guide.
Its supposed to clearly show you how to override for example:
Instead of what i put in my original setup, i had to add:

	list override 'battery_charge_low'      <-------
	list override 'battery_runtime_low'     <-------

config override 'override_battery_charge_low'
	option value '95'
config override 'override_battery_runtime_low'
	option value '5000'

Secondly:
The reason why ups.status didnt trigger ups.status: OB LB so that a shutdown can actually occur, was because i didnt include the option ignorelb
Which wasted a few hours of my life trying to figure out why when putting ignorelb in /etc/config/nut_server did not generate it at all inside /etc/nut/ups.conf, and that was because you had to put: option ignorelb 1 under driver section. The 1, is supposed to "switch it on" apparently. How i found this? i stumbled on the options on Github: https://github.com/openwrt/packages/blob/master/net/nut/files/nut-server.init
Does it show this on the official wiki? no it doesnt.

Finally:
For some reason i removed the option option shutdowncmd '/usr/sbin/nutshutdown' and replaced it with option shutdowncmd '/sbin/halt' in /etc/config/nut_monitor which wasnt actually powering off the UPS. /usr/sbin/nutshutdown was supposed to be explained on the wiki.
Simply like this: /usr/sbin/nutshutdown - A script that checks for powerkill flag and if its there, command is sent to poweroff the UPS and then lastly poweroff the router. OR replace with your own script, if you have a special setup.

/sbin/halt is for shutting down current system, ie. router. which should not plainly be shown in the sample https://openwrt.org/docs/guide-user/services/ups/software.nut#nut_monitor_default_file

Why does this have to be so difficult? Because sadly registrations in editing the wiki are disabled, and no-one will go to great lengths and bother to ask for access either.

I really hope this helps other OpenWRT NUTters in here.
