error connecting to KNX device

Hello,


I'm getting many "error connecting to KNX device".


On my first system (Grinder), this is happening from times to times, for a very short period of time (<1 min). 

This is not impacting the good operation of the system, except if this happening when bOS needs to issue a KNX command, but that's very rare, and then I noticed an impact only once.

I thought that maybe this was linked to my IP network that needed some troubleshooting.


But I've got another system, a KNX Jigsaw, for which the KNX error connecting to device is occurring every 2 minutes ! The KNX interface being incorporated into the Jigsaw, this can't be an issue with my environment. 

I'm not using KNX on this Jigsaw, so I just disables the KNX interface, and problem was fixed for me. 


Still I would like to understand how to fix these "error connecting to device" incidents. 


I'm also getting them from times to times for all IP-connected devices: global Caché, Philips Hue, Denon amplifier, etc... 


Thanks,

François

Hello,

@dave, could you email us information for the server so we can check what's happening with the hardware (there could be something wrong with the KNX module on the device). Additional info on how to connect will be provided, please contact us: david.boben@comfortclick.com

@Nasser, did you try deleting the page and adding it back in? Also, what are you displaying on this page?

Best regards,

Hey,

I noticed that the reconnecting thing is back for one of my building that is running bOS 4.4.4, But with Falcon driver. 

Disconnects for 10sec and reconnects. Strangely 2 smaller buildings that are setup as KNXIP dont do these reconnects, and 1 bigger building that is setup as KNXIpTunneling does not do this.

Log show that this has been going on like this for two months. Not sure what has changed. 

Edit: I was wrong about the bigger building not doing this, I looked again at the logs and it does the same reconnects but not everyday. It did disconnect/reconnect 7 times on 11.10.19 last friday after that there has been no disconnects.

hello,

Same type of issues here. The problem went away this summer after moving to KNX IP (Falcon)... but it’s back for a few weeks now.

Tonight, after upgrading to version 4.6.1 I now get a more detailed error message that reads as follow : “Error connecting to device. BusConnectionStatus.Broken”.

Any tips?

Thank you

Netit

I can join the group here, recently updated my bOS to the latest (non-beta) version and KNX (through USB) disconnects and connects again within 0.5 minute around 2 to 3 times per 24h.  Most of the time it's not an issue but from time to time it doesn't send or receives any more KNX messages after this event even though the status is connected again.  Only thing I can do is open bOS Config and disconnect and reconnect KNX manually. I'm running a Wienzierl USB interface on a Minix Windows 10 mini-PC.  It worked fine for about 3 years now so I'm suspecting something changed in the bOS KNX driver ?  I already ran the "Fix USB issue" feature that seems to be new in bOS Config but without succes.  I also made sure the Windows option "allow Windows to turn off this device to safe power" is DISABLED for all USB ports in the Windows Device Manager.  It's really frustrating since it for example doens't turn on my heating system, my curtains, alarm clocks in the morning etc... This needs to be solved or I'll have to find another visualization package which would be a shame since I really like bOS.

I’m also on a Minix. Not sure this is related.
