This is interesting.
I had my Z-Wave stick at /dev/ttyACM0’ already working with the apt-get installation of OH2 (the snapshot version maybe 1-2 month old). Yesterday I made and apt-get upgrade and now Z-Wave stops at this line: Connecting to serial port '/dev/ttyACM0'. The controller is offline with reason “Serial Error: Port /dev/ttyACM0 does not exist”.
I didn’t had this option (EXTRA_JAVA_OPTS=-Dgnu.io.rxtx.SerialPorts=/dev/ttyACM0) before but even setting it doesn’t make a difference.
Finding this thread, I installed liblockdev1 and finally it works! So my guess would be that the latest nrjavaserial needs the liblockdev1 as a dependency (at least on raspberry pi 2)?
From the other thread:
I can see this liblockdev1 mentioned several times in github tickets of the nrjavaserial repository, however it is not mentioned there in the readme as a prerequisite.
Anyway to automate this installation in OH2…?
