Integrating KNX and OpenZWave with Node Red

[Ηλίας Καρακουλάκης]

Hi all. I'm happy to announce that I finally have a working integration between two of the most popular home automation protocols, KNX and ZWave using Node-Red flows.
The integration is bidirectional and I can control
- ZWave devices from KNX commands sent to a specific groupaddress
- KNX status groupaddresses sent as a result of a manual ZWave operation

Here's a teaser:

Good job! :)

I'm sure others would like to try them if you felt like sharing them :-)

oops you're right I forgot the link! :)

I'm going to get these nodes properly packaged for npm now...

Elias nice one hope to see this covered in KNX Journal one day soon!

Looks like your using eibDemon did you use the Busware ROT board?

Hi Lawrence,

I'm interfacing to an eibd running on my Logic Machine (http://openrb.com/), a dedicated KNX box I have for quite some time, but this is irrelevant; I could be running eibd locally on the RPi and use a Busware ROT as the physical adapter for KNX...

both nodes involved are now published in npm repositories:

https://www.npmjs.org/package/node-red-contrib-eibd
https://www.npmjs.org/package/node-red-contrib-openzwave

Cheers!

Hi,

small nitpick - the license in the files is apache2, the license entry in their package.json says BSD.

Hello Elias,

great to see you worked on this. I am using LogicMachine as well, could you please share your LM scripts? Would help me finally get my flat in shape, thanks a lot.

Peter

Hi Peter,

the plan is to replace LogicMachine completely :) :) I'm lacking time-critical functions (eg delayed execution), that's the main reason...

Hello Elias,

Thanks for your quick reply. I do not plan to get rid of LM, because I need it for other tasks. Could you share the scripts anyway pls? 

Thank you

Reading the current KNX Journal  http://www.weinzierl.de/ Wweinzierl announce.

The kBerry SDK for the Raspberry Pi is available as a free download

Hoping this in Python and not thier normal C/C++ SDK 

[Ηλίας Καρακουλάκης]

this looks to belong in the BAOS family, afaik this is high-level IP-based knx object api, which is not suitable for raw bus access I think - I also think it poses a limit on the number of available objects.

Hello,

Openrb wrotes on the forum that you are writing a KNX-ZWAVE connection for the logicmachine? : http://forum.logicmachine.net/showthread.php?tid=4

Is that true? And do you have any idea when other people can use/test this?

I like to use the Zwave Fibaro motion sensors /door sensor and wall plug into my LogicMachine/KNX.

Thanks.

Hi,

I'm using the LogicMachine for my KNX-ZWave integration, but only as an IP gateway. I've not extended the LM as it lacks even the most basic development essentials (I've got a version 1 unit which its not an ARM variant, but a PPC.. - no compiler, 32MB of RAM...). I've tried in the past to set up a cross-compilation environment which kinda worked but it was simply too fragile.

The KNX-ZWave integration runs as a Node-Red flow in a stock Raspberry Pi. 

Hope this helps!
