Add-Ons

Now I have this in /etc/nut/upsmon.conf (my QNAP NAS wants admin and 123456 or not working)

RUN_AS_USER root
MONITOR qnapups@localhost 1 admin 123456 master
# MONITOR qnapups@192.168.222.252 1 admin 123456 slave

And in /etc/nut/upssched.conf

CMDSCRIPT /etc/nut/upssched-execscript.sh

PIPEFN /etc/nut/upssched.pipe
LOCKFN /etc/nut/upssched.lock

AT ONBATT * START-TIMER shutdown_onbatt 240
AT ONBATT * EXECUTE info_onbatt

AT ONLINE * CANCEL-TIMER shutdown_onbatt
AT ONLINE * EXECUTE ups-back-on-power

AT LOWBATT * EXECUTE shutdown_lowbatt

AT REPLBATT * EXECUTE replace_batt

And in /etc/nut/upssched-execscript.sh

#! /bin/sh
case $1 in
    shutdown_onbatt)
        logger -t upsmon[upssched] "shutdown_onbatt): Triggering shutdown after 4 minutes on battery"
        /sbin/shutdown -h +0
        ;;

    shutdown_lowbatt)
        logger -t upsmon[upssched] "shutdown_lowbatt): Triggering shutdown when battery.charge.low is under 50%"
        /sbin/shutdown -h +0
        ;;

    info_onbatt)
        logger -t upsmon[upssched] "info_onbatt): Now on battery"
        ;;

    ups-back-on-power)
        logger -t upsmon[upssched] "ups-back-on-power): UPS back on power"
        ;;

    replace_batt)
        message="Quick self-test indicates battery requires replacement"
        logger -t upsmon[upssched] "replace_batt): $message"
        ;;

    *)
        logger -t upsmon[upssched] "*) = Unrecognized command: $1"
        ;;
esac

And in /etc/nut/ups.conf

[qnapups]
    driver = usbhid-ups
    port = auto
    desc = "UPS"
    ignorelb
    override.battery.charge.low=50

And in /etc/nut/upsd.users

[admin]
                password = 123456
                actions = SET
                instcmds = ALL
                upsmon master           # or upsmon slave

So I have these files

[root@ipfire2 nut]# pwd
/etc/nut
[root@ipfire2 nut]# ls -la
total 104
drwxr-xr-x  2 root root  4096 Jan 10 09:23 .

Do that seem right to you?

EDIT: I added:

PIPEFN /etc/nut/upssched.pipe
LOCKFN /etc/nut/upssched.lock

EDIT 2
After info in the post under this post, I in this post above changed from this
MONITOR qnapups@192.168.222.252 3493 admin 123456 slave
to this:
# MONITOR qnapups@192.168.222.252 1 admin 123456 slave

And I also added /etc/nut/upsd.users above
