knxultimate
KNX IP protocol implementation for Node. This is the ENGINE of Node-Red KNX-Ultimate node.
Control your KNX intallation via Node.js!
This is the official engine of Node-Red node KNX-Ultimate (https://flows.nodered.org/node/node-red-contrib-knx-ultimate) I had many users asking for a node.js release of that engine, so here is it. The node will be KNX Secure compatible. I'm already working on that.
CHANGELOG
VOLUNTEER NEEDED FOR KNX SECURE
KNX-Secure is under development and should be ready by mid 2022.
Many users requested me to "extract" the baseline KNX API from Node-Red KNX-Ultimate node and make it accessible via npmjs. Here is it.
I need volunteer helping in development of KNX Secure.
High knowledge of cryptography and KNX is needed.
Properties to be passed to the connection(see the knxUltimateClientProperties variable below)
| Property | Description |
|---|---|
| ipAddr (string) | The IP of your KNX router/interface (for Routers, use "224.0.23.12") |
| ipPort (string) | The port, default is "3671" |
| physAddr (string) | The physical address to be identified in the KNX bus |
| suppress_ack_ldatareq (bool) | Avoid sending/receive the ACK telegram. Leave false. If you encounter issues with old interface, set it to true |
| loglevel (string) | The log level. "info", "error", "debug" or "trace" |
| localEchoInTunneling (bool) | Leave true forever. This is used only in Node-Red KNX-Ultimate node |
| hostProtocol (string) | "Multicast" if you're connecting to a KNX Router. "TunnelUDP" for KNX Interfaces, or "TunnelTCP" for secure KNX Interfaces (not yet implemented) |
| isSecureKNXEnabled (bool) | True: Enables the secure connection. Leave false until KNX-Secure has been released. |
| jKNXSecureKeyring (string) | ETS Keyring JSON file content (leave blank until KNX-Secure has been released) |
| localIPAddress (string) | The local IP address to be used to connect to the KNX/IP Bus. Leave blank, will be automatically filled by KNXUltimate |
| KNXEthInterface (string) | "Auto": Bind to the first avaiable local interfavce. "Manual": if you wish to specify the interface (for example eth1); in this case, set the property interface to the interface name (interface:"eth1") |
| interface (string) | Specifies the local eth interface to be used to connect to the KNX Bus. Do not add this parameter if you've set KNXEthInterface to "Auto" |
Supported Datapoints
For each Datapoint, there is a sample on how to format the payload (telegram) to be passed.
For example, pass a true for datapoint "1.001", or { red: 125, green: 0, blue: 0 } for datapoint "232.600".
It support a massive number of Datapoints. Please run the sample.js file to view all datapoints in the console window.
Be aware, that the descriptions you'll see, are taken from Node-Red KNX-Ultimate node, so there is more code than you need here. Please take only the msg.payload part in consideration.
You should see something like this in the console window (the msg.payload is what you need to pass as payload):
CONTROL THE CLIENT
| Method | Description |
|---|---|
| .Connect() | Connects to the KNX Gateway |
| .Disconnect() | Gracefully disconnects from the KNX Gateway |
| .write (GA, payload, datapoint) | Sends a WRITE telegram to the BUS. GA is the group address (for example "0/0/1"), payload is the value you want to send (for example true), datapoint is a string representing the datapoint (for example "5.001") |
| .respond (GA, payload, datapoint) | Sends a RESPONSE telegram to the BUS. GA is the group address (for example "0/0/1"), payload is the value you want to send (for example true), datapoint is a string representing the datapoint (for example "5.001") |
| .read (GA) | Sends a READ telegram to the BUS. GA is the group address (for example "0/0/1"). |
| Properties | Description |
|---|---|
| .isConnected() | Returns true if you the client is connected to the KNX Gateway Router/Interface, false if not connected. |
| ._getClearToSend() | Returns true if you can send a telegram, false if the client is still waiting for the last telegram's ACK or whenever the client cannot temporary send the telegram. In tunneling mode, you could also refer to the event KNXClientEvents.ackReceived, that is fired everytime a telegram has been succesfully acknowledge or not acknowledge. See the sample.js file. |
EVENTS
Please see the sample.js file. This sample contains all events triggered by KNXUltimate.
DECONDING THE TELEGRAMS FROM BUS
Decoding is very simple. Just require the dptlib and use it to decode the RAW telegram
const dptlib = require('./src/dptlib');
let dpt = dptlib.resolve("1.001");
let jsValue = dptlib.fromBuffer(RAW VALUE (SEE SAMPLES), dpt); // THIS IS THE DECODED VALUE
Simple sample (you can find this sample in the "simpleSample.js" file):

const dptlib = require('./src/dptlib');
// Set the properties

loglevel: "error", // or "debug" is the default
localEchoInTunneling: true, // Leave true, forever.
hostProtocol: "Multicast", // "Multicast" in case you use a KNX/IP Router, "TunnelUDP" in case of KNX/IP Interface, "TunnelTCP" in case of secure KNX/IP Interface (not yet implemented)
isSecureKNXEnabled: false, // Leave "false" until KNX-Secure has been released
jKNXSecureKeyring: "", // ETS Keyring JSON file (leave blank until KNX-Secure has been released)
localIPAddress: "", // Leave blank, will be automatically filled by KNXUltimate
KNXEthInterface: "Auto", // Bind to the first avaiable local interfavce. "Manual" if you wish to specify the interface (for example eth1); in this case, set the property interface to the interface name (interface:"eth1")
};
// Instantiate the client

}
console.log("src: " + _src + " dest: " + _dst, " event: " + _evt, " value: " + jsValue);
});

console.log("Connected. On Duty", info);
// WARNING, THIS WILL WRITE ON YOUR KNX BUS!
knxUltimateClient.write("0/1/1", false, "1.001");
});
