WORK IN PROGRESS

Configure NUT

  • First edit the /etc/ups/ups.conf file by appending the battery info. You can find this information by running nut-scanner
[root@dronetest ~]# nut-scanner -U
Cannot load XML library (libneon.so.27) : file not found. XML search disabled.
Scanning USB bus.
[nutdev1]
	driver = "usbhid-ups"
	port = "auto"
	vendorid = "0764"
	productid = "0601"
	product = "OR1500PFCLCD"
	serial = "GXIFS2000130"
	vendor = "CPS"
	bus = "001"


  • With the information above, append the following to /etc/ups/ups.conf
[nutdev1]
        driver = usbhid-ups
        port = auto
  • For basic email alerting, create the following script and associated cronjob.

NOTE : This is a work in progress. This script would send you a ton of emails and is not smart enough to everything it needs to.

#!/bin/bash
branch='location name'
nutdevcount='1'
nutdevlist='nutdev1'
support='support@yourcompany.com'
for i in $nutdevlist; do
	upsstatus=$(upsc $i@localhost ups.status)
	upsload=$(upsc $i@localhost ups.load)
	[ ! -z $upsstatus ] && [ ! -z $upsload ] &&
	if [ "$upsstatus" = "OL" ]; then
		echo "Battery Online" > /dev/null
	elif [ "$upsstatus" == "OB DISCHRG" ]; then
		echo -e "Subject:$branch UPS has lost AC Power" | /usr/sbin/sendmail "$support"
	elif [ "$upsstatus" = "OL CHRG" ]; then
		echo "Charging" > /dev/null
	else
		echo "Status Unknown" > /dev/null
	fi
	if [ "$upsload" -ge "70" ]
		then echo -e "Subject:$branch UPS Load=$upsload" | /usr/sbin/sendmail "$support"
	fi
done

Start NUT service Layers

systemctl enable --now nut-server

Old Startup Type

The following was used before I ran across the systemd unit files that came with the package. The other issue is that I am now getting the following error that makes this setup no longer usable in it's current state.

[/etc/systemd/system/nutstart.service:6] Failed to parse service type, ignoring: Simple

Have the following shell script in place

#!/bin/bash
sudo usbhid-ups -uroot -a nutdev1
sudo upsd -uroot

Then create the systemd unit file /etc/systemd/system/nutstart.service with the following

[Unit]
Description=Start NUT services
After=network.target

[Service]
Type=Simple
ExecStart=/root/nutstart.sh

[Install]
WantedBy=default.target

Then enable the service
