Homematic java.util.concurrent.TimeoutException

Hey guys,
since few days i receive some error logs related to my homematic. several items are not available and after few minutes everything seems to be fine.

Can you help me to identify the reason?

CCU3 (debmatic) and openHAB 3.3.0.M3
Binding Homematic 3.3.0.M3
are on the same PI

Hi Simon,

does this alway happen for the same device or device type? Or for different devices?

What kind of Raspi is it?

Hi this happens for some random devices.
Its an Raspberry 4 with 4gb RAM and Debianos.

This kind of problems is really hard to debug. I don’t know anything about debmatic. But I think that there are also log files in debmatic (maybe you have to increase a log level). Can you check these logs whether there are any entries at the same time(s) the problem in OH happens?

Please excuse my late answer. I am quite busy currently.

The problem seems to happen deep in the communication between OH and the CCU. It is nearly impossible to debug. A possible solution could be to intercept this exception and retry again.

Hi martin, if you could explain to me what i should do, i could try to intercept it.

This has to be implemented within the binding. There is already some sort of retry mechanism for the communication between OH and the CCU but it seems that it is not sufficient.

I have installed new openhabian Image and the issue seems to be gone.:grin:
