SmartBus Build Status

Node.js implementation of HDL SmartBus protocol http://hdlautomation.com

Initialization

Create instance of SmartBus connector

var SmartBus = require('smart-bus');

var bus = new SmartBus({
  subnet: 1,
  id: 50,                   // Device id for connector
  gateway: '192.168.1.250', // HDL SmartBus gateway IP

  port: 6000                // Listening port, default: 6000
});

Receive commands

Add handler to intercept all commands across bus

bus.on('command', function(command) {

  // Integer with command operation code
  command.code;

  // Device objects
  command.sender;
  command.target;

  // Object with decoded data or raw buffer
  // if data can not be parsed automatically
  command.data;

});

Handlers can be added for broadcast messages or specific commands

bus.on('broadcast', function(command) { ... });
bus.on(0x0032, function(command) { ... });

Listen for commands from specific device

var sensor = bus.device('1.20');

sensor.on(0x1647, function(data, target) { ... });

Send commands

Use connector to send commands

bus.send('1.4', 0x0031, { channel: 1, level: 100 }, function(err) { ... });

Or use device object

var logic = bus.device('1.10');

logic.send(0xE01C, { switch: 1, status: 1 }, function(err) { ... });

Both send methods accepts raw Buffer as data object. In case if data object can not be encoded error will be passed into callback.

DSL

Initialize channel object

var dimmer = bus.device('1.4');
var spotlights = dimmer.channel(2);

Listen to channel status event

spotlights.on('status', function() {
  console.log('Spotlights level is %s', spotlights.level);
});

Set device channel level value to 100 in 5 seconds

spotlights.control(100, { time: 5 }, function(err) { ... });

control function will send 0x0031 command into bus.
