Hi!

Hi Michael

There is no any group address or device except my knx push button, its group address is 2/0/8.
Yes it is coming from knxd, i am sure.
Because there is no any telegram when i connect to bus from other weinzierl ip interface.

Thanks

In the meantime,

I have written to email Weinzierl company.
I have tested their other baos serial gateway 870.
It is working with usb- serial ftdi gateway, no problem.
The binding of openhab can work it, but kberry doesn’t work.
Their support team is also working for this issue.
Mr.Karl from Weinzierl has written that that “it seems the openhab always uses EMI2 communication for a serial connection to KNX, the 870 uses also EMI2, but the kBerry uses cEMI. After a little research, openhab seems to use Calimero for serial communication, which would have a driver for cEMI, but I did not find a possibility to switch to this driver”
So i think problem point is here…
How can we switch this driver, really i dont know too.
Because i am not software specialist, i am only knx specialist an integrator :slight_smile:
Is there anybody who can help us for this issue?
If we can solve this, the knx connection will be more cheaper in this way.

Many thanks

Regards.

Made a basic implementation of openhab2 binding using ObjectServer protocol.

I believe it will be easier to install and configure than knxd/calimero/etc.

Also patched calimero-core and compiled with native knx binding to use with BAOS 838 kBerry:

Hi,
is there a way to install knxd without openhabian? I am running openhab on raspbian and got no openhabian-config command.

For openHAB 3 see this one KNX BAOS module 838 Kberry - #7 by petero

Hi, for all who want to turn Pi with kBerry into KNXNet gateway, take a look at

So after you have setup UART run llpub at first and then llnet. You may use two ssh sessions or tmux software as well. If everything is ok, you will be able to connect ETS(with NAT option enabled).
I’m not sure about OH, anyway - didn’t test it.

From ETS you will be able to work with group addresses as well as with transport connections - so it is possible to program device applications.
