Hi there!
I’m having trouble configuring NUT to shutdown the load when getting a low battery from the battery. Everything works but from my understanding, when arriving to call the shutdown script : /usr/sbin/nutshutdown, the driver does not seem to be able to call this command properly to kill the load :
/lib/nut/"${driver}" -a "$cfg" -k
and since the load is still ON, the router reboot indefinitely but i’m unsure why. Here’s the part commanding the shutdown :
# Driver will wait 'offdelay' before shutting down
config_foreach shutdown_instance driver
# So this can happen
rm -f /var/run/killpower
poweroff
# And just in case
sleep 120
# Uh-oh failed to poweroff UPS
reboot -f
What confuses me is that, if I unplug the power from the router, the UPS shutdown after a short while like it was waiting for the router to stop polling when it has a low battery condition. But from my understanding, this is not the wanted behaviour since I should be able to command the immediate shutdown.
Here’s what works until now :
- Instant commands : ex : shutdown the load immediately.
- NUT CGI
- Low battery event.
- Wait for other systems running nutmon in secondary mode to shutdown.
- Start the shutdown sequence.
Here is the UPS model :
Back-UPS NS 1500M2
Here is the current OpenWRT version :
OpenWrt 22.03.5 r20134-5f15225c1e / LuCI openwrt-22.03 branch git-23.093.57104-ce20b4a
Here are the configuration files :

In other words;
Why is the UPS not shutting down when the low battery sequence is initiated?
