2020-06-10 20:15:52.999 [WARN ] [nx.internal.connection.KNXConnection] - KNX link has been lost (reason: server request on object tunneling link link (closed) TP1 medium, device 0.0.0, hopcount 6)
2020-06-10 20:15:53.173 [ERROR] [.binding.knx.internal.bus.KNXBinding] - Received detach Event.

next entry is also an error:

2020-06-10 20:15:53.481 [WARN ] [t.mqtt.internal.MqttBrokerConnection] - MQTT connection to 'mqttson' was lost: Connection lost : ReasonCode 32109 : Cause : null
2020-06-10 20:15:53.484 [INFO ] [t.mqtt.internal.MqttBrokerConnection] - Starting connection helper to periodically try restoring connection to broker 'mqttson'
2020-06-10 20:16:03.495 [INFO ] [t.mqtt.internal.MqttBrokerConnection] - Starting MQTT broker connection 'mqttson'

i can’t see anything else that could be relevant.
KNX setup worked flawless until now.
As soon as i send a command to knx via habpanel switch connection is established again:

2020-06-10 20:39:58.676 [INFO ] [nx.internal.connection.KNXConnection] - Established connection to KNX bus on in mode TUNNEL.

In the last days i had some random openhab restarts so i have set DEBUG for org.apache.karaf

this isn’t probably enough to help you help me… what would help? setting DEBUG for knx?

best regards

happened again today :dizzy_face:
