View source for Home Assistant - NUT UPS Energy Tracking

If you have a UPS (Uninterruptible Power Supply) that has either a USB connection or ethernet connection, you can likely add it to Home Assistant Server as an energy tracking device. This guide is generic enough to work with most USB UPS but I am using a Cyberpower CP1000, and have 2 of them showing up as an energy tracking device in my Home Assistant Energy section.

== Install NUT ==
Network UPS Tools also called NUT is the tool we run on Linux to track UPS features. 
 sudo apt update
 sudo apt install nut

== Edit /etc/nut/nut.conf ==
The default mode is none, so lets change it to standalone in this file
 MODE=standalone

== Edit /etc/nut/ups.conf ==
We need to add our UPS to this file so NUT knows what driver to use. Add this section to your ups.conf. Name your ups in the square brackets, it doesn't have to say cyberpowerb, this is just mine.
 [cyberpowerb]
      driver = usbhid-ups
      port = auto
      desc = "Cyberpower CP1000 B"
      pollfreq = 30

If you are having detection problems, add this line to your ups.conf config just under the driver line. Replace with your UPS vendor ID (find via lsusb)
 vendorid = 0764

== Edit /etc/nut/upsd.conf ==
Add a LISTEN directive, you can have more than one. Port separated by a space. Default is 3493. You may not want to open your LAN IP here.
 LISTEN 192.168.1.100 3493
 LISTEN 127.0.0.1 3493

== Edit /etc/nut/upsd.users ==
Add this to create a user that can read UPS stats.
 [local_mon]
       password = mysupersecretpass
       upsmon master

== Edit /etc/nut/upsmon.conf ==
Add your UPS to the bottom to be monitored
 MONITOR cyberpowerb@localhost 1 local_mon mysupersecretpass master

(otional) You may want to change polling to be less frequent
 POLLFREQ 15

(optional) If your UPS goes stale, change when it assumes it is dead
 DEADTIME 30

(optional) I stopped the computer from turning off the UPS on reboot by adding "no" or anything else to the end
 POWERDOWNFLAG /etc/killpowerno
