Hello,
System-Info below…
My Problem:
I use a RasPI 3B+.
I use Z-Wave with a USB-Stick and EnOcean with EnOceanPi (the small Add-On-Board).
I moved the BT device (I want to use it for presence-detection) to /dev/ttyS0 by an overlay.
When ever I make changes to the configuration of the Z-Wave Stick. The communication to it gets lost because the system says, that the serial port is not availabe.
On the inital Installation of the Z-Wave-Stick I entered the port (/dev/ttyACM0) --> It was a textfield.
Now this field is empty and its no textfield any more. Now I have to choose the port and there is only the port of the EnOcean-Board available.
When I restart the OH2-Service, the Z-Wave-Stick is online again after about 20 secs. The EnOcean-Board takes 2 - 3 Minutes. The long time is strange but no problem for me.
Some Z-Wave-Things need other TeachIn-Settings than others so I had to boot a few times to get all the Things in. But it looks like ther is someting wrong wit hthe hardware-binding…
I tried OpenHABian but there I was not able to get the Z-Wave-Stick online again. Does not matter what I tried 
Thanks for any Help
Robert
