I am experiencing notorious Z-Wave issues with battery devices since the heating period started this year. My Danfoss LC13 thermostats (which worked just fine for 5 years until now) started become unresponsive and the same goes for the battery wall switches I have. They work fine for some days or even weeks eventually stop working until they are power cycled. The LC 13 devices show the dreaded E5-Error. I have searched the forums for this issue but could not really find a solution for this. I have ex- and included, hard and soft reset, deleted and re-initialized the devices, but nothing helped for long. The only thing that’s different now is that I have ghost devices in the controller which can’t be removed because the exclusion did not work or I did a factory reset too early.
Half of my non-battery devices also show Status: OFFLINE - COMMUNICATION_ERROR Node is not communicating with controller
in Paper-UI but they are still accepting commands.
Two days ago suddenly the whole z-wave Network become unresponsive and I had to restartet OH to make it functional again. The Logfile contained this exception:
2020-11-27 08:53:03.144 [WARN ] [WaveSerialHandler$ZWaveReceiveThread] - Exception during ZWave thread.

I have the feeling my z-wave network is slowly falling apart.
I am using a VIS_ZU1401 stick and the latest OH 2.5 release from the Debian repository.
Is there anything I can do?
