This man page only documents the specific features of the \fBnut\-upower\fR driver\&. For information about the core driver, see \fBnutupsdrv\fR(8)\&.
.sp .5v
.RE
.SH "DESCRIPTION"
.sp
This driver allows the monitoring of power devices (UPS, batteries) that are managed by the UPower daemon via the D\-Bus system bus\&.
.sp
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\&.
.SH "EXTRA ARGUMENTS"
.sp
This driver supports the following optional settings in \fBups.conf\fR(5):
.PP
\fBport\fR
.RS 4
The UPower Object Path of the device to monitor\&.
.RE
.sp
If set to auto (the default), the driver will scan for the first UPower device whose object path contains the string "ups_"\&.
.sp
If set to a specific path (e\&.g\&., /org/freedesktop/UPower/devices/ups_hiddev0), the driver will attempt to monitor that specific device\&.
.PP
\fBlowbatt\fR
.RS 4
The battery percentage threshold below which the
LB
(Low Battery) status flag is set\&. The default value is 20\&.0\&.
.RE
.SH "INSTALLATION"
.sp
To use this driver, add a section to your \fBups\&.conf\fR:
.sp
.if n \{\
.RS 4
.\}
.nf
[myups]
    driver = nut\-upower
    port = auto
    lowbatt = 20
    desc = "Laptop Battery or generic UPS via UPower"
.fi
.if n \{\
.RE
.\}
.SH "REQUIREMENTS"
.sp
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\&.
