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

if you're facing these issues and are both running windows machines, try changing the connection type to KNXnetIPTunneling and try using our Falcon KNX connection type and see if there are any improvements.

Hello

I've modified the setup this morning on my Grinder as you suggested.

So far, so good ; but let's wait a couple of days to confirm.

Are there similar solutions on Jigsaw ? My second system is a Jigsaw KNX.

Hey,

This trick worked for my gateways too, so far no disconnects.

5 days without a single error ; that's great. Thank you so much for your help.

Hello. In last few months I been having Jigsaw KNX issue where KNX cannot connect to KNX bus. In the end I have been forcet to use external IP/KNX device. In last update there was KNX improvments in notes but same problem is occuring. Any solution for this?

there could be some issues with the KNX module on the device, or could be a simple KNX driver update that can be done manually. Please contact me at david.boben@comfortclick.com and we can schedule a remote session and check the KNX connection and resolve this issue.

Best regards.

hello

I am also facing the KNX Connection issue ,

it was working with 4.5.0 version

but when I updated to latest i.e 4.5.12 .

it started giving error of KNX Connection

{ Devices : 7/28/2019 1:41:33 PM : Error : Devices\KNX : Reconnect: OnDataReceived: Index was outside the bounds of the array.}

I tried knx ip/routing FALCON Connection type but no solution

we're already working on fixing the problem with the Index was outside the bounds... error. You should be able to see this resolved with our future updates

I'm also having issues on a previous working installation (Jigsaw). It looks like the server won't receive information from knx.

i've checked the wiring, 29V goes in the jigsaw.

when i push a button on the comfort click it keeps giving no respons, (worked previous fine) until a power failure.

ETS5 won't receive information from the knx.

Jigsaw server version: 4.5.14
