Example how to use

In this example you can see, how to register for group object updates and how to send updates.

var knx=require ('knxnetjs');

//open KNXnet/IP connection
var KNX = knx.openKNX();

//start datapoint engine used to easily send and receive knx group addresses
var DPE = knx.createDPEngine(KNX);

//register a datapoint under a name with a datapoint type to a specific group address
DPE.registerDP("Scenes", "5.010", "1/0/1");

DPE.registerDP("switchable_light", "1.001", "1/1/1");
DPE.registerDP("dimmable_light", "5.001", "1/1/2");

//the following event is called for incoming group address write to a known group address
DPE.on("updateDP", function (dp, value) {
  //check which datapoint is written
  if (dp === "Scenes") {
    //check value, in this case the scene number
    if (value == 0) {
      //everything off
      DPE.sendDP("switchable_light", "OFF");
      DPE.sendDP("dimmable_light", 0);
    } else if (value == 1) {
      //some light scene
      DPE.sendDP("switchable_light", "ON");
      DPE.sendDP("dimmable_light", 127);    
    }
  }
}
