This document describes how to install the CyberPower UPS daemon. The main advantage of using a CyberPower UPS is that it is cheap and it can communicate with your Linux box through either a RS-232 or USB serial connection. In the event of a prolonged power outage, should the CyberPower UPS lose most of its battery capacity, it can tell the Linux box to perform a safe shutdown.

Installation

Install powerpanel (powerpanelAUR) from AUR.

Configuration

Edit /etc/pwrstatd.conf

Email notifications can be accomplished by editing /etc/powerpanel/pwrstatd-powerfail.sh and /etc/powerpanel/pwrstatd-lowbatt.sh

Warning: Make sure the path to the email script at the bottom of these scripts is correct. It should be /etc/powerpanel/pwrstatd-email.sh

Running

Start and enable the service

# systemctl start pwrstatd
# systemctl enable pwrstatd

Then run # pwrstat -status

You should get something like this:
