NAME
       nut-upower - Driver for UPower devices via D-Bus

SYNOPSIS
       nut-upower -h

       nut-upower -a UPS_NAME [OPTIONS]

           Note

           This man page only documents the specific features of the
           nut-upower driver. For information about the core driver, see
           nutupsdrv(8).

DESCRIPTION
       This driver allows the monitoring of power devices (UPS, batteries)
       that are managed by the UPower daemon via the D-Bus system bus.

       It maps UPower properties (state, percentage, voltage, etc.) to
       standard NUT variables, allowing NUT clients to monitor devices that
       are natively supported by the OS desktop environment but not directly
       by other NUT drivers.

EXTRA ARGUMENTS
       This driver supports the following optional settings in ups.conf(5):

       port
           The UPower Object Path of the device to monitor.

       If set to auto (the default), the driver will scan for the first UPower
       device whose object path contains the string "ups_".

       If set to a specific path (e.g.,
       /org/freedesktop/UPower/devices/ups_hiddev0), the driver will attempt
       to monitor that specific device.

       lowbatt
           The battery percentage threshold below which the LB (Low Battery)
           status flag is set. The default value is 20.0.

INSTALLATION
       To use this driver, add a section to your ups.conf:

           [myups]
               driver = nut-upower
               port = auto
               lowbatt = 20
               desc = "Laptop Battery or generic UPS via UPower"

REQUIREMENTS
       This driver requires the upower daemon to be running and accessible via
       the D-Bus system bus. It also requires GLib 2.0 and GIO libraries.
