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.
   
   
   

Here, a table is displayed containing UPS:

• Model name
• Status
• Charge level
• Line voltage
• Load
• Estimated run time.
  

Here, a list of text strings displays with all the information retrieved from the UPS.

This contains the same data as the other tools (like the apcupsd UPS control daemon on a Windows LAN 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.
