SmartBus

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

Manipulate device channel status.

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

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

level function will send 0x0031 command and then pass contents of 0x0032 response into callback.
