The UPS Monitor menu has settings and information to let you monitor your Uninterruptible Power Supply.

Monitoring is available only for APC UPSes with a USB connection compatible with the APC smart protocol library. The UPS Monitor library is included only in the Mega-VPN and AIO builds.

The menu is divided in two sections:

1. The APC UPS Status table.
2. and APC UPS Response strings.

For more details, see: https://networkupstools.org/protocols/apcsmart.html

To establish a connection:

1. In the USB Support menu, enable USB 1.1 support (OHCI)
2. Enable the Run APCUPSD Daemon option. Click Save.
   

This section contains a table displaying the UPS model name, status, charge level, line voltage, load, and estimated run time.

This section contains a list of text strings with all the information retrieved from the UPS.

This contains the same information as the other tools (such as the apcupsd utility daemon for controlling UPSes on a local network windows machine, http://www.apcupsd.org/)

A good way to debug issues with the UPS daemon is to check the Logs menu for entries that indicate successful startup.

For example, see the last entry shown on this Logs screen:

The last log entry shown here indicates that the apcupsd daemon started without problems.
