node-red-contrib-knx-ultimate

DESCRIPTION

• Knx-ultimate device node 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.
• WatchDog node 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.

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.

Double Personality

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).

Emulate real KNX device

You can use the node to emulate a phisically non existent KNX device. The node will behave exactly as a normal KNX Device and will also respond to read requests coming from the KNX bus, by sending the current payload value to the KNX bus.

Customizable status display

You can select what to see in the status (the row below the node). For example, you can select to see the current payload value and the last time changed, or the device name as well.

Self protection

The Node protects you, from youself. 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.

Automatic KNX interface type

Full support for IP Interfaces as well for IP Routers. It's recommended the use of IP Routers because of simple setup and stability in a large environment.

Old interfaces friendly

The "Suppress ACK" option, helps compatibility with old IP Interfaces, like the Siemens SWG1 148-1AB22 IP Interface firmware etc...

Granular options

The node is very simple to use "out of the box", but you can plasmate it to achieve any goal you want.

WATCHDOG Node for KNX backup connection and notification

You can check the healty of your KNX Bus connection and switch over to anoter KNX/IP Router if the primary fails.

WATCHDOG Node to change the KNX gateway configuration on the fly

Programmatically change the IP, Port etc... of the KNX/IP Interface or router, via msg.

ACTIVE DEVELOPED

I personally use my node at home, so i put a lot of effort to develop it and i respond to your "github issues" very quickly

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.
