Hi.
I have an up and running home automation with z-wave communication built on openzwave, using a Z-stick (gen 1). Now I’m planning a migration over to openHAB (on the same server using the same Z-stick). During a transitional period the old solution needs to keep working while I fiddle around with OH, setting up all that is required for the move. I hope I can get some help here with how to do that…
It’s no problem for me stopping the openzwave application an hour or two while I’m doing stuff in OH, thus handling over control to the Z-stick to the OH binding. Thing is though that after that I need to be able to handle control back to openzwave (since it’s still the system in production) and I don’t know if that’s possible. Can I simply stop the binding using bundle:stop?
I hope you understand my problem (though I’m not really sure if it’s really a problem or only me thinking too much). I haven’t even dared installing the binding yet since I’m not really sure what’ll happen and I still need my openzwave home automation working…
Ok. Tested this approach. Simply stopped my openzwave program, installed the z-wave binding and configured it to talk to /dev/ttyUSB0 (which is where my Z-stick is). The only thing Paper UI keeps saying me now though is
Status: OFFLINE - COMMUNICATION_ERROR Serial Error: Port /dev/ttyUSB0 does not exist
/dev/TTYUSB0 definitely exists and it’s read/writeable by dialout group, in which my openhab user is member. Anyone able to say what I’m doing wrong now?
edit: Tried debug logging the binding. Don’t know if this tells anyone something about what’s wrong?

Just for the record: This wasn’t a good idea. First two switches seems to have worked nice, but after that my openzwave application completely refused talking to the device anymore. On the other hand it was quite easy integrating my old solution with openhab’s rest interface, so now I don’t need openzwave anymore anyways
In general, it shouldn’t matter. I often swap a stick between different machines / software / etc. Maybe OZW is caching some information that screws it up, but not sure what or why as no data is cached on the stick.
