OH 4: KNX bridge sporadically loses connection

Dominik_Bernhardt · November 25, 2023, 5:09pm

I have the problem that since some time the KNX ip bridge loses the connection. In the logfile I can see a corresponding log statement. After the log statement “close connection” there are no KNX related logs anymore. The KNX IP Bridge Thing as well as all other KNX Things are still shown as online, however there are no values retrieved anymore and commands are not send to the devices. When I manually disable the bridge and enable it again everything works fine again.
The issue occured approximately when I switched my openhab system from a raspi4 to a NUC system but I actually don’t see this beeing the issue. In general the system had been working reliable since 2015!
Currently I’m on OH 4.1.0 M2 but it also occured on OH 4.0
Any idea what might causing the issue. And why does it not try to reconnect?

I have now solved the issue for me by automatically disabling and re-enabling the KNX bridge Thing when a one of my KNX items is not updated for a while.

stamate_viorel · December 2, 2023, 12:29pm

why are you polling the individual devices ? is there a reason for that ?

ByteBandito · March 25, 2024, 8:52pm

Hi Dominik,
can you share how excactly you do so?

My knx-bridge does the same since some days after some months running without any problems - and I did not change anything
Thx,
Patrick

Hi Patrick,

Interestingly, the problem with my KNX bridge disappeared as suddenly as it appeared. What I did while it was there was to monitor one of my items connected to a KNX Thing (in my case a temperature sensor) to see if it is not sending an update for too long (I expect it to send every minute). If this happens, I automatically disable and re-enable the bridge.
I’m doing all this scripting in Python via HABApp. However, I’m pretty sure you could do it directly in Openhab. For example, I could think of the following:

Set the expire metadata of one of your KNX items to set the item to a certain value if it is not updated long enough.
Define a rule that listens for this specific value
Deactivate and re-activate the KNXBridge thing. I don’t know how exactly this would be done in OpenHAB. But either it can be done directly in JS or you could use the REST API.

Hope this helps,
Dominik
