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. 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 other tools (like apcupsd UPS control daemon on a Windows LAN device: http://www.apcupsd.org/)

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

For example, see the last entry on this screen:

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