KNX Link has been lost

[ScanxTaz]

Hi !

Sorry for :

1. The English
2. Waking up dead thread, but I've a question about the "time out"...
I've finally adopted OH2, which seems to be a good framework for what I'd like to do
It was working for a while (maybe 2 months) now, and I've decided this week-end to improve a little bit, integrating recurrent updates about temperature probes for my ventilation system.

I don't know if this issue was existing before, nor if it's really related with the read, from the KNX bus, of the probe temperature, but now, suddenly, the KNX calimero driver start to loose connection with the knx interface.

The interface I use is the USB one from Eibmarkt...

USB HID Device [KNX-USB Manufacturer KNX-USB Interface (Rail mounted)]

I know, you'll say that it's not the perfect one, but it did the job for years with KNXWEB, and I'd like to keep it if possible (expensive at that time), and also, I've no more place for an IP gateway in my electricity panel.

So, the logs of the issue (you'll see, suddenly the "cannot find an active data connection" appears from nowhere... I'm even not doing anything at all..

My knx.cfg configuration :

ip=192.168.0.100
port=3671
busaddr=15.15.229
ignorelocalevents=true
timeout=10000
pause=100
tuwien.auto.calimero=DEBUG

Could you please help me ???

The "funny" thing is that I see KNXD still working properly in journalctl, where the logs continue to "run" normally, and I see the telegrams from my probes sending values on the KNX bus, but nothing is happening anymore in OH2 logs (karaf nor /var/log/openhab2/*.log)

Thanks a lot !

Please try the english forum for openHAB https://community.openhab.org/.

As I don't use knxd, I'm afraid I can't help about this problem at all.

Thanks, the point is that this forum is much more active, and speaking about KNXD and OpenHab

Ok, I'll try to find my way there #sad

[udo1toni]

the point is that this forum is much more active,

not really
Speaking of this forum, when very active, thare are about 10 posts a day (only openHAB folder), but it's also normal to see no postings at all for more than two or three days in a row.
In the english forum, you will hardly find a day with less than 50 postings, and this is also only openHAB. Even more, all developers are frequently online in the english forum so chances there are higher to get the correct information.
