Idle timeout from Loxone Miniserver closes connection to binding - keep alive not working

Hello,

Since a few days the Loxone binding keeps disconnecting from my Loxone Miniserver after no activity. I have adjusted the keep alive messages in incremental steps down to 1s, but it doesn’t help.

This shows up in my log:

openhab.log

2020-04-11 02:33:47.715 [WARN ] [ding.loxone.internal.LxServerHandler] - Idle timeout from Loxone Miniserver - adjust keepalive settings

2020-04-11 02:33:47.747 [INFO ] [se.smarthome.model.script.alarm.rule] - loxone thing status changed

events.log

2020-04-11 02:33:47.722 [hingStatusInfoChangedEvent] - 'loxone:miniserver:504F9410E8E0' changed from ONLINE to OFFLINE (COMMUNICATION_ERROR): Timeout due to no activity

I get no other error messages, everything seems to work as it should. I have been integrating new Z-wave sensors including compiling a new binding, maybe this is to blame? It seems as if the keep alive messages are either not being sent out or are not being accepted by the Miniserver. I don’t know where I can see or monitor the keep alive messages.

My setup:

  • Hardware: RaspberryPi 4
  • OS: Raspbian GNU/Linux 10 (buster)
  • Java Runtime Environment: openjdk version “1.8.0_222”
  • openHAB version: 2.5.3-1
  • Loxone Firmware: 10.3.11.25

Thanks in advance for any help!

Wim.

Set the binding to DEBUG via the console and see if you get any additional info to help identify the problem.

Hello @H102,

Thanks for pointing me towards the DEBUG mode. I’ve learned a lot in the process, but alas, I haven’t found the direct cause.

I noticed the pattern is always the same: for no apparent reason, the binding stops sending keepalive messages to the miniserver, and then after a long enough period of inactivity, the connections times out and is shut down. I look for several things / tried different approaches:

  • I found no error messages at the time of last keepalive message.
  • I found no specific events that always occur at the time the keepalive messages stop.
  • I turned down the time between keepalive messages to 10s to limit the amount of activity between keepalive messages, but nothing obvious or recurrent shows up.
  • I uninstalled the z-wave binding because I’ve had this problem since I installed a self-compiled z-wave binding, but this hasn’t changed a thing.
  • I put the Loxone binding in TRACE mode to get even more info, but nothing special shows up.

I’m pulling my hair out over this!

I hope someone can help me solve this since the Loxone binding has become useless for me.

Best regards,

Wim.

Found something on github regarding your miniserver firmware version:

"The Miniserver forgot the authentication tokens after the upgrade. You need to delete the token and Enter password again in the binding configuration."
