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.
