APCUPSD-UPS(8)

NAME
apcupsd-ups - Driver for apcupsd client access

SYNOPSIS

apcupsd-ups -h

apcupsd-ups -a UPS_NAME [OPTIONS]

    Note

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

DESCRIPTION

This driver is a client to apcupsd (another UPS monitoring project).

apcupsd-ups acts as an apcupsd client, simply forwarding data. This can be useful in cases where both protocols are required in a network, or in case apcupsd code base has a required UPS access mode missing from NUT.

EXTRA ARGUMENTS

This driver supports the following optional settings in nut.conf(5):

port=<hostname>[:<port>]
    This is the name of a remote host running apcupsd (plus an optional port).

For instance:

    [apcupsd]
            driver = apcupsd-ups
            port = localhost
            desc = "apcupsd client"

BACKGROUND

This driver was originally written in one evening to allow interoperating with apcupsd.

SUPPORTED VARIABLES

The following variables are translated from apcupsd to NUT. All times should be converted to seconds (please file a bug if you notice a mismatch in units).
apcupsd variable | NUT variable(s)
BCHARGE | battery.charge

RETPCT | battery.charge.restart
BATTDATE | battery.date
TIMELEFT | battery.runtime
MINTIMEL | battery.runtime.low
BATTV | battery.voltage
NOMBATTV | battery.voltage.nominal
LINEFREQ | input.frequency
SENSE | input.sensitivity
HITRANS | input.transfer.high
LOTRANS | input.transfer.low
LASTXFER | input.transfer.reason
LINEV | input.voltage
MAXLINEV | input.voltage.maximum
MINLINEV | input.voltage.minimum
NOMINV | input.voltage.nominal

SELFTEST | ups.test.result

LIMITATIONS

Access to apcupsd is strictly read only: no commands can be issued. This stems from the design of apcupsd, where the settings are changed in apctest. In order to run apctest, apcupsd must be stopped (and it is apcupsd that exposes the UPS to the network and to this NUT driver as its client).
