KNX/IP Routing Integration

[jakub.jezek.personal 1]

Hello,

 

With help of AI (using Gemini), I am trying to integrate KNX devices via KNX/IP Routing protocl to Fibaro. I am working more with KNX devices these days, so I wanted to try to get them into Fibaro UI . I started with the switch as it is easiest to implement. I have working Commands, link in the end of post. Now me and AI hit roadblock with Feedbacks.

 

Have you worked with UDP Sockets before? Seems like some parts of net class are either missing or unavailable. To me it looks like net.getInterface is not implemented.

Working switch 1-way:

If you wanna use it, just use it. I am giving the 1-way one (commands only) as it is.

 

Command Group Address: 1/0/0 (high byte 8 is 1/0, Low byte 0 is .../0)

 

For now KNX Group Addresses are "Hardcoded" till it works even with Feedbacks.

This QA works with KNX/IP Routing protocol (multicast), so for your test with KNX installations you need KNX/IP Router, like

. KNX/IP interfaces (unicasts) are not supported.

 

For some wondering, I am @jakub.jezek, I am just using different account on my personal PC if I am out of office or on vacation.

I cant help you, but would love to see an integration with KNX

There actually is an integration with KNX, with logicmachine from openrb. It was discussed on the English Discord.

Yes, that is possible, but Logic Machine costs something about 1000 Euro, just the box. KNX/IP Router is about 365 Euro (price for

).

 

@m.roszak, any idea how to make Fibaro listen on UDP Multicast? Multicast Ip would be 224.0.23.12 and port 3671.

And I dont know how it works, But if we do a request to the gateway with the multicast ip and port and "open" a socket and set the timeout for 60sec, and reopen each 60sec or right after reciveing some data? 

 

I dont have a gateway to test against myself at the moment 🤔 
But I will check if you could get one from work 😅

Thanks @Brors94, I used this to create devices that can send data to KNX (Switching and Dimming).

 

I'll try to see what I can do about it, but as I am doing it in my free time its quite challanging as I do not have that much free time at office where we have KNX
