NODE'S LIST

• KNX-ULTIMATE node here, allow you to control your KNX installation via Node-Red. You can control all your KNX devices as well as create a Virtual Device in Node-Red, to link external non KNX devices, and make it compatible with your KNX installation. I'ts very SIMPLE TO USE thus very customizable.
• SCENE CONTROLLER node here, The scene controller node can act as a real scene controller, with recall and save of the current scene.
• WATCHDOG node here, allows notification (Email, Twitter, Telegram, Alexa, Siri, Sonos -with sonospollytts node- and so on) of KNX Bus connection errors, automatic or manual switchover to a backup KNX/IP router if the primary fails and allows you to programmatically change the config-node directly from a msg flow. It also can force the disconnection and connection of the selected Gateway from the KNX BUS.
• LOGGER node here, creates an XML diagnostic file, compatible with ETS. You can open it with ETS for diagnostic pourposes. Node: the Logger currently doesn't record the telegrams coming from KNX-Ultimate if you use a KNX/IP Interface.
• GLOBAL CONTEXT node here, exposes the group addresses to a Global Context variable, to be used in function nodes.
• ALERTER node here. With the Alerter node you can signal to a display or to the node-red-contrib-tts-ultimate node (audio feedback), whenever the selected devices are alerted, i.e. they have payload true.
• LOAD CONTROL node here. Control your loads (Oven, Washing machine, etc..) and avoit shutting down the main voltage due to too high power consumption.
• VIEWER node here. View all Group Addresses and values of your KNX BUS, in the Node-Red Dashboard.
• AUTO RESPONDER node responds to read requests coming from the bus. Used mainly for virtual group addresses.
• PHILIPS HUE nodeset here. Link HUE devices to KNX in a simple way.
• HOME ASSISTANT translator node here translates the HA input msg, to a KNX value. Comes with a built-in translation table, that's user editable.

Highlights

If you're here, you probably already have tried other knx nodes from npm. I hope you enjoy this one, because i've put big effort to do what i really needed, a copy/paste friendly node, with many functions and the possibility to use the ETS csv exported Group Addresses.

Stand alone or with ETS exported file

You can set you own group address, datapoint and device name, or you can import the ETS Group Address list and have datapoint and device name auto populated while typing in the group address.

Filling helpers

If you import your ETS CSV or ESF file, just begin typing the group address or the device name in the Group Address textbox and a list of possible matches will appear. Just select an item in the list it and have datapoint and device name auto populated. You can then accept the auto populated fields or change it.

Automatic encoding/deconding of KNX datagrams

Just pass a normal payload to the node (true, false, a string or any nymber) and just receive a normal payload (true, false, a string or any nymber) to use in your flow.

As single device, as Universal node.

The node can act as a single device (for example having Group Address 0/0/1), or can be used as universal node, catching all messages coming from KNX Bus (in this case the node will output a comprehensive msg to the flow, containing group address, device name, automatic decoded payload and other useful infos). The node can act as universal KNX sender as well (you can pass a message to the node, containing the destination group address, the datapont type and the payload).

Contextual help for formatting input messages

There is samples. There is huge documentation about settings and properties. If this is not enough for you, whenever you change the datapoint type, a textblock with a sample msg input (expecially, for tricky datapoints, like RGBW, 10Bytes, Relative Dimming, 3 Bytes setpoint etc...) appears. Just copy/paste it in a function and you're done.

Huge amount of Datapoints are supported

It supports a huge amount of datapoints. If you need more, just open a GitHub issue.

Self protection

The Node protects you, from mistakes you can do. Node Protections

Built in RBE input/output filter

You can select to activate or deactivate it. If active, the node reacts only if payload from KNX Bus or from input msg is changed.

RAW message directly to the BUS

You can send RAW buffers directly to the bus.

WORKING WITH THE ETS CSV FILE OR WITH ESF FILE

Instead of create a knx-ultimate node for each Group Address to control, you can import your ETS csv or esf group addresses file.
Thanks to that, the knx-ultimate node where you selected Universal mode (listen to all Group Addresses), becomes an universal input/output node, aware of all Datapoints, Group Addresses and Device's name (ex: Living Room Lamp). Just send the payload to the knx-ultimate node, and it'll encode it with the right datapoint and send it to the bus. Likewise, when the knx-ultimate node receives a telegram from the bus, it outputs a right decoded payload using the datapoint specified in the ETS file.

ARE YOU A NODEJS DEV? DO YOU KNOW THERE IS AN API FOR NODEJS?

Many users requested me to "extract" the baseline KNX API and make it accessible via npmjs. Here is it.
The API is named KNXUltimate. In the README page is well documented and there are also samples for unsecure and secure KNX connections.
