NAME
Device::Neurio - Methods for wrapping the Neurio API calls so that they are accessible via Perl
VERSION
Version 0.14
SYNOPSIS
This module provides a Perl interface to a Neurio sensor via the following
methods:
- new
- connect
- fetch_Samples
- fetch_Samples_Full
- fetch_Samples_Last_Live
- fetch_Samples_Recent_Live
- fetch_Stats_Energy
- fetch_Appliances
- fetch_Appliances_Events
- fetch_Appliances_Specific
- fetch_Appliances_Stats
Please note that in order to use the 'Samples' methods in this module you will
require three parameters (key, secret, sensor_id) as well as an Energy Aware
Neurio sensor installed in your house. In order to use the 'Appliances'
methods, you will also require another parameter (location_id). This information
can be obtained from the Neurio developpers website.
The module is written entirely in Perl and was developped on Raspbian Linux.
All date/time values are specified using ISO8601 format (yyyy-mm-ddThh:mm:ssZ)
SAMPLE CODE
use Device::Neurio;
$my_Neurio = Device::Neurio->new($key,$secret,$sensor_id,$debug);
$my_Neurio->connect();
$data = $my_Neurio->fetch_Samples_Last_Live();
print $data->{'consumptionPower'}
$data = $my_Neurio->fetch_Samples_Recent_Live("2014-06-18T19:20:21Z");
print $data->[0]->{'consumptionPower'}
undef $my_Neurio;
EXPORT
All by default.
SUBROUTINES/METHODS
new - the constructor for a Neurio object
Creates a new instance which will be able to fetch data from a unique Neurio
sensor. All three parameters are required and can be obtained from the
Neurio developpers website.
my $Neurio = Device::Neurio->new($key, $secret, $sensor_id, $debug);
This method accepts the following parameters:
- $key : unique key for the account - Required
- $secret : secret key for the account - Required
- $sensor_id : sensor ID connected to the account - Required
- $debug : turn on debug messages - Optional
Returns a Neurio object if successful.
Returns 0 on failure
connect - open a secure connection to the Neurio server
Opens a secure connection via HTTPS to the Neurio server which provides
access to a set of API commands to access the sensor data.
An optional location ID can be given. This is only required if calls
will be made to the 'Appliance' methods. Calls to the 'Samples'
methods do not require that a location ID be set. If a location_id is not
specified at connection, then it must be specified when using the 'Appliance'
methods.
A location ID can be acquired from the Neurio developpers web site
$Neurio->connect($location_id);
This method accepts the following parameter:
- $location_id : unique location id - Optional
Returns 1 on success
Returns 0 on failure
fetch_Samples_Recent_Live - Fetch recent sensor samples

The values represent the sum of all phases.
$Neurio->fetch_Samples_Recent_Live($last);
This method accepts the following parameters:
