NAME
    Device::Plugwise - Perl module to communicate with Plugwise hardware

VERSION
    version 0.5

SYNOPSIS
      my $plugwise = Device::Plugwise->new(device => '/dev/cu.usbserial01');
      $plugwise->command('on', 'ABCDEF'); # Enable Circle#ABCDEF
      while (1) {
        my $message = $plugwise->read();
        print $message, "\n";
      }

      $plugwise = Device::Plugwise->new(device => 'hostname:port');
      $plugwise->command('on', 'ABCDEF'); # Enable Circle#ABCDEF

DESCRIPTION
    Module for interfacing to Plugwise hardware.

    Current implemented functions are

    Switching ON/OFF of circles
    Query circles for their status
    Query the Circles+ for known circles
    Retrieve the live power consumption of a Circle
    Readout the historic power consumption of a Circle (1-hour average)

    IMPORTANT: This module required Plugwise firmware v2.37 or higher.

METHODS
  "new(%parameters)"
    This constructor returns a new Device::Plugwise object. Supported
    parameters are listed below

    device
        The name of the device to connect to, The value can be a tty device
        name of "hostname:port" for a TCP connection. This parameter is
        required.

    filehandle
        The name of an existing filehandle to be used instead of the
        'device' parameter.

    baud
        The baud rate for the tty device. The default is 9600.

    port
        The port for a TCP device. There is no default port.

  "device()"
    Returns the device used to connect to the equipment. If a filehandle was
    provided this method will return undef.

  "baud()"
    Returns the baud rate. Only makes sense when connected over a serial
    connection.

  "port()"
    Returns the TCP port for the device. Only makes sense when using this
    type of connection of course.

  "filehandle()"
    This method returns the file handle for the device.

  "list_circles_count()"
    This method returns the number of Circles that will be interrogated with
    the list_circles command. If you have more than 16 Circles in your
    network, increase the setting to a higher value.

  "read([$timeout])"
    This method blocks until a new message has been received by the device.
    When a message is received the message string is returned. An optional
    timeout (in seconds) may be provided.

  "read_one(\$buffer, [$do_not_write])"
    This method attempts to remove a single message from the buffer passed
    in via the scalar reference. When a message is removed a data structure
    is returned that represents the data received. If insufficient data is
    available then undef is returned.

    By default, a received message triggers sending of the next queued
    message if the $do_no_write parameter is set then writes are not
    triggered.

  "write($command, $callback)"
    This method queues a command for sending to the connected device. The
    first write will be written immediately, subsequent writes are queued
    until a response to the previous message is received.

  "queue_size()"
    This method reports the number of commands that are in the queue to be
    sent to the stick.

  "status()"
    This method returns the status of the internal _plugwise hash. This can
    be used to extract network information and for debugging. Hash entries
    include

    connected : is the software connected to the USB stick
    stick_MAC : Zigbee MAC address of the stick
    network_key : Full zigbee network ID
    short_key : Short version of the network ID
    circles : List of IDs of Circles that have responded to a calibration
    request and that hence are known to be active on the wireless network

  "command($command, $target)"
    This method sends a command to the stick.

    Supported $commands with a target id are:

    on : switch a circle on
    off : switch a circle off
    status : request the current switch state, internal clock, live power
    consumption
    livepower : request the current power measured by the Circle
    history : request the energy consumption for a specific logaddress

    $target can either be a single short hardware MAC address or a
    comma-separated list of devices if multiple devices need to receive the
    same command.

ACKNOWLEDGEMENTS
    The code of this module is heavily based the code by Mark Hindess
    (Device::Onkyo), thanks Mark! The initial Perl Plugwise interface code
    for firmware v1 was written by Jfn.
