UPS on Linux

Install nut

The following example is for Tripp Lite UPS
Verify the Tripplite UPS:

# lsusb
Bus 002 Device 026: ID 09ae:2010 Tripp Lite 

Edit /lib/udev/rules.d/52-nut-usbups.rules and make sure the line below exists:

ATTR{idVendor}=="09ae", ATTR{idProduct}=="2010", MODE="664", GROUP="nut"

Reload the udev files:

udevadm control --reload-rules

My UPS definition in /etc/nut/ups.conf:

[tripplite_ups]
    driver = usbhid-ups
    port = auto
    vendorid= 09ae
    productid = 2010
    desc = "Tripp-Lite UPS"

(The library file is located in /lib/nut)

My /etc/nut/upsd.conf:
LISTEN 127.0.0.1        3493
LISTEN 192.168.25.168   3493
LISTEN 192.168.1.1      3493
LISTEN ::1              3493

Restart the driver:

$ sudo upsdrvctl start
Network UPS Tools - UPS driver controller 2.7.2
Network UPS Tools - Generic HID driver 0.38 (2.7.2)
USB communication driver 0.32
Using subdriver: TrippLite HID 0.81

If no error, that means everything is working fine.

My /etc/nut/upsd.users contains:

[upsmon]

    password = pass

    upsmon  master

My /etc/nut/upsmon.conf contains:

MONITOR tripplite_ups@localhost 1 upsmon pass master

SHUTDOWNCMD "/sbin/shutdown -h +0"

NOTIFYCMD /usr/local/bin/upsnotifyme

NOTIFYFLAG COMMBAD SYSLOG+WALL+EXEC

NOTIFYFLAG SHUTDOWN SYSLOG+WALL+EXEC

NOTIFYFLAG REPLBATT SYSLOG+WALL+EXEC

NOTIFYFLAG NOCOMM SYSLOG+EXEC

NOTIFYFLAG NOPARENT SYSLOG

Restart the nut-server and client:

sudo service nut-server restart

OptiPlex-9020:/lib/udev/rules.d$ sudo service nut-client restart

                          

                                                                     

If it works, your PC can now communicate with UPS.
