[ERROR] [ing.zwave.handler.ZWaveSerialHandler] - Got I/O exception Input/output error in writeArray during sending. exiting thread

Hello Chris,

I switched already to an Xtreamer nuc / pc and installed not an openhabian installation but a plain openhab.
So i can’t give you the log anymore. Otherwise i have now also a lot of problems with switches and popp thermostats. Everything what communicate with ip from openhab to another device (like the Anel PwrHut relais) works perfect.
Squeezebox works fine. Only zwave is an difficult chapter… I use Qubino Flush 2 relay, Qubino dimmer dinrail and Popp zwave radiator knop. But i’m thinking to buy a Tado heating set. Then is the heating system standalone.
But stil the zwave problem remains with the dimmer en relais. After a couple of times to pair the device. All the items wil work. Sometimes it doesn’t report the enery level. Or the temprature or the manual switch command won’t be updated to openhab.

I also reading the ticket OH2 Z-Wave refactoring and testing... and SECURITY
Is it possible that the binding not working well? Thousands of people use zwave.
Are there things i can try to solve the problem?

Kind regards Thetmar
