I thought that NUT would handle this. But perhaps it cannot for my
unit? Or perhaps I have things improperly configured? Any suggestions?
Thanks and happy new year!

Happy New Year David!, The command "/sbin/upsdrvctl shutdown" turns off
the UPS unit, but this is not being executed. How do you plan to shut
down on power failure? Will you wait for upsd's [LB] status or use a
timer? The simplest is to wait for [LB], but the upsmon.conf contains
no declarations for NOTIFYFLAG LOWBATT.
The script /home/android/nutShutdown.sh will be called when wall power
fails, but nut-report was unable to show its contents. Should
nutShutdown.sh perform the system shutdown?
Perhaps a more complete set of NOTIFYFLAG and NOTIFYMSG declarations
will make things clearer. I would also recommend adding the SYSLOG
option to the declarations.
Do you shutdown using systemd?

Hi Roger and, as always, thanks!
I really do not want to wait very long before shutting down things on
this UPS. What I think I am doing (or at least trying to do) is to
execute a script on the host machine when the UPS is detected by NUT to
be on battery power.
That script sleeps 20 seconds to ensure that this was not just a power
blip (which happens here often) but a real power outage. After 20
seconds, the script checks the UPS status via upsc and if it is no
longer OB, power is deemed restored and the script exits.
If, after 20 seconds, UPS status remains OB then the event is deemed a
true power outage and I want to shut down what I can cleanly. To do
this, the script issues remote shutdown commands to a set of network
connected devices also living on this UPS (but sadly not able to run
NUT). As its final step, it issues a command to shut the host machine down.
It seems from what you say above, I need to issue "/sbin/upsdrvctl
shutdown" in there somewhere - obviously before I shut the host machine
down. I will have to test this to see exactly what that command does.
When run w/out arguments, the usage says shutdown shuts down UPS
drivers. I am not clear if this means that the UPS itself will be
powered off or if simply NUT is shutdown.
Thanks
