zibase

A NodeJS API to ZiBase

Introduction

This module is a SDK to connect to a Zibase. Most of it should be working fine, as it is currently used in a real home automation installation. However, it has been tested so far only against a Zibase Classic.

This SDK is strongly inspired from the PHP SDK written by Benjamin Garel.

Installation

Install as a npm module:

npm install zibase

Usage

Use as a npm module:

var zibase = require('zibase');

Connection to a Zibase

In order to communicate with a Zibase it is necessary to connect to it by instanciating the ZiBase class. For this, the IP address zibaseIP and the credentials deviceId and token of the Zibase are needed.

var Zibase = new zibase.ZiBase(
                   zibaseIP,
                   deviceId,
                   token);

An optional callback parameter can be used to be notified once the Zibase has been recognized.

var Zibase = new zibase.ZiBase(
                   zibaseIP,
                   deviceId,
                   token,
                   function (err) {
                       if (err)
                           console.log(err);
                       else
                           console.log("Connection established.");
                   });

It will initialize a connexion to the Zibase, register the calling application as a client of the Zibase, letting the Zibase send its activity information to the client. The first message sent by the Zibase indicates that the registration was successful:

21/02/2016 20:32:51.929 <info> zibase.js:424 (ZiBase.processZiBaseData) Zapi linked to host IP=<zip>192.168.0.10</zip> UDP Port=<zudp>60580</zudp>

Descriptors

The descriptors of the Zibase are loaded when the ZiBase class is instanciated. They can be accessed through:

  • the ZiBase.descriptors member:
console.log(Zibase.descriptors);

will produce:

 [ { type: 'device',
    name: 'Ventilation SdB',
    t: 'receiverXDom',
    i: 'logotype_airfan.png',
    c: 'C3' },
  { type: 'device',
    name: 'Conso Wall Plug',
    t: 'power',
    i: 'logotype_power.png',
    c: 'PZA3' },
  { type: 'device',
    name: 'Pompe à Chaleur',
    t: 'receiverXDom',
    i: 'logotype_heatpomp.png',
    c: 'P7',
    p: '5' },
  { type: 'scenario',
    name: 'simulation intrusion',
    id: '9',
    icon: 'logoMacro_Portes.png' },
  { type: 'scenario',
    name: 'Notification iOS',
    id: '16',
    icon: 'logoMacro_Scenario.png' }
 ]
  • the ZiBase.getDescriptor(id) method:
console.log(Zibase.getDescriptor("P7"));

will produce:

{ type: 'device',
  name: 'Pompe à Chaleur',
  t: 'receiverXDom',
  i: 'logotype_heatpomp.png',
  c: 'P7',
  p: '5' }

Variables

The variables V0 to V31 can be read through ZiBase.getVariable:

Zibase.getVariable(10, function(err, value) {
    if (err)
        console.log(err);
    console.log("V10=" + value);
});

Devices

The state of devices can be retrieved through ZiBase.getState:

Zibase.getState("ZB5", function(err, value) {
    if (err)
        console.log(err);
    console.log("ZB5 state =" + value);
});

Sensors

The information about a sensor can be retrieved through ZiBase.getSensorInfo:

Zibase.getSensorInfo("OS439157578", function(err, value) {
    if (err)
        console.log(err);
    console.log("Infos =" + value);
});

Events

The activity of the Zibase is logged through tracer messages:

21/02/2016 22:00:48.955 <info> zibase.js:352 (ZiBase.processZiBaseData) Received radio ID (<rf>ZWAVE ZB5</rf> <dev>Low-Power Measure</dev> Total Energy=<kwh>121.4</kwh>kWh Power=<w>00</w>W Batt=<bat>Ok</bat>): <id>PZB5</id>

The ZiBase object is an event emitter that can call registered callbacks when receiving a given activity message. The supported events are:

  • message: this event is emitted each time the Zibase sends a message
  • change: this event is emitted each time the Zibase sends a message about a device
  • error: this event is emitted when a ZWAVE error message is sent by the Zibase
  • restart: this event is emitted when the Zibase is restarting
  • restarted: this event is emitted once the Zibase has restarted

Listening to events is done with on(event, id, callback), or once(event, id, callback) in which case the event is triggered only once.

The following code:

Zibase.on('change', "PZB5", function(msg){
     console.log(msg);
});

will produce the following output:

21/02/2016 21:36:20.553 <info> zibase.js:352 (ZiBase.processZiBaseData) Received radio ID (<rf>ZWAVE ZB5</rf> <dev>Low-Power Measure</dev> Total Energy=<kwh>121.4</kwh>kWh Power=<w>00</w>W Batt=<bat>Ok</bat>): <id>PZB5</id>
{ rf: 'ZWAVE ZB5',
  dev: 'Low-Power Measure',
  kwh: '121.4',
  w: '00',
  bat: 'Ok',
  id: 'PZB5' }

Deconnexion

When no more interaction with the Zibase is needed, it is recommended to deconnect from it thanks to deregisterListener().

Zibase.deregisterListener();

The effect of this call is to ask the Zibase to stop sending its information. It seems the Zibase can keep track of 4 clients only. When a fifth client is registered, it will replace the oldest one, hence causing a forced deregistration of the first client. When using a single client, it usually not a problem to not call deregisterListener(). However, when using several clients connected to a single Zibase, it is highly recommended to make the call, to avoid the others from being disconnected. A good practice is to use the following code:

function exitHandler() {
    Zibase.deregisterListener();
    console.log("Deregistered from Zibase.");
}

process.on('exit', exitHandler);
process.on('SIGINT', exitHandler);
process.on('uncaughtException', exitHandler);
