Hello, I am using a Aeon Gen 5 Z-Stick successfully with OH1. I am working to migrate to OH2 (online build, installed via apt-get), and continuously receive this error in the logs: ``` 2016-12-25 17:39:36.548 [hingStatusInfoChangedEvent] - 'zwave:serial_zstick:159387b2735' changed from INITIALIZING to OFFLINE (BRIDGE_OFFLINE): Controller is offline 2016-12-25 17:39:36.645 [hingStatusInfoChangedEvent] - 'zwave:serial_zstick:159387b2735' changed from OFFLINE (BRIDGE_OFFLINE): Controller is offline to OFFLINE (COMMUNICATION_ERROR): Serial Error: Port /dev/ttyACM0 does not exist ``` My /etc/default/openhab2 file looks like this: `EXTRA_JAVA_OPTS=-Dgnu.io.rxtx.SerialPorts=/dev/ttyACM0` I have also tried injecting export -Dgnu.io.rxtx.SerialPorts=/dev/ttyACM0 into various places in the karaf and many other startup files, with no luck. OH2 is running as openhab, and is a member of the dialout group, which has rw privileges on /dev/ttyACM0. Any ideas on how to make this port available to OH2? ---

That’s odd. Normally, the only place you need to put the serial port is in the config of the Z-Wave Serial Controller thing. ---

This could be completely unrelated, but in case it’s not, [this commit](https://github.com/openhab/openhab-core/commit/ba9ff5389f089629eb6560295be0fd6ffc4bb795) updated nrjavaserial from 3.9.3 to 3.12.1 three days ago. ---

I am using the snapshot version of OH2 via apt-get. If I installed today l, I should have this latest build right? How can I check? ---

You can find the build number by logging into the karaf console. [http://docs.openhab.org/administration/console.html](http://docs.openhab.org/administration/console.html) According to Cloudbees, the latest build is 674. [https://openhab.ci.cloudbees.com/](https://openhab.ci.cloudbees.com/) ---

I was having a similar issue with an existing install. Did two things in parallel and one of them fixed it: Installed this library: [RFXCom issue on RP3 - #5 by marky](https://community.openhab.org/t/rfxcom-issue-on-rp3/18282/5) And did an apt-get update/upgrade and am now back online. Hope one or both help your install (I’d start with an upgrade). ---

I’m on the latest snapshot via apt-get. There is not a liblockdev1 package of my Ubuntu build (16.04)… I’ll spend more time troubleshooting tomorrow. ---

Same issue here : ``` events.log:2016-12-25 18:39:46.226 [hingStatusInfoChangedEvent] - 'zwave:serial_zstick:159363163fa' changed from OFFLINE (BRIDGE _OFFLINE): Controller is offline to OFFLINE (COMMUNICATION_ERROR): Serial Error: Port /dev/ttyACM0 does not exist ``` Setup: apt-get , online, RPi2, tellstick. Had working tellstick setup with OH1, moved to OH2 ( no apt-get ) and got that working. Moved to apt-get to get hold of code progress and to get Habmin to work from zwave support. Funny thing is, Habmin2 have been able to extract the one node I had discovered before plugging it in and set it up as an item. \<\<\>Rant\> Now neither tellstick not zwave works. Reading forums to find out small stuff like default sitemap isn’t default, that /etc/group file needs to be edited. I update files, but paper UI does not … Almost all is found out by forums and google, very little by the documentation. OH is making me older fast. \<\<\>/Rant\> ---

had same issue z-wave (Razberry) ACM0 not working with latest builds. i was using openhabian to update my system. As nolan\_garrett was saying something wrong with OS. After those two steps, i am back in business. - Update system sudo apt-get update - Install: liblockdev1-dev package sudo apt-get install liblockdev1-dev All works again. ---

Thanks, tried that , with mixed success. Openhab didin’t start on reboot. Or rather ,died. And I’m assuming it was unexpectedly. Nothing in the openhab.log: ``` 2016-12-26 08:02:54.626 [INFO] [ui.habmin.internal.servlet.HABminApp] - Started HABmin servlet at /habmin 2016-12-26 08:02:55.046 [INFO] [panel.internal.HABPanelDashboardTile] - Started HABPanel at /habpanel 2016-12-26 08:02:55.669 [INFO] [ding.astro.internal.job.JobScheduler] - Scheduled a daily job at midnight for astro calculation 2016-12-26 08:03:01.974 [INFO] [ing.zwave.handler.ZWaveSerialHandler] - Connecting to serial port '/dev/ttyACM0' ``` Nor in the event.log: ``` 2016-12-26 08:03:01.971 [hingStatusInfoChangedEvent] - 'zwave:serial_zstick:159363163fa' changed from UNINITIALIZED to INITIALIZING 2016-12-26 08:03:01.977 [hingStatusInfoChangedEvent] - 'zwave:serial_zstick:159363163fa' changed from INITIALIZING to OFFLINE (BRIDGE_OFFLINE): Controller is offline 2016-12-26 08:03:02.062 [hingStatusInfoChangedEvent] - 'zwave:device:159363163fa:node2' changed from UNINITIALIZED (HANDLER_MISSING_ERROR) to INITIALIZING 2016-12-26 08:03:02.068 [hingStatusInfoChangedEvent] - 'zwave:device:159363163fa:node2' changed from INITIALIZING to OFFLINE (BRIDGE_OFFLINE): Controller is offline ``` The /var/run/openhab2.pid file was still there though. Even worse, when I removed liblockdev1 and liblockdev1-dev, I only hade PAPER UI and BASIC UI in the web interface. But it started again. Edit: When I look in the PAPER IU , the zWave binding is gone. ---

You did not write anything about the most important step: adding user openhab to dialout group. That is the only thing I had to do with the latest build of Raspbian and the latest build of openHAB2: ``` 2016-12-25 10:48:16.317 [INFO] [ing.zwave.handler.ZWaveSerialHandler] - Connecting to serial port '/dev/ttyACM0' 2016-12-25 10:48:16.620 [INFO] [ing.zwave.handler.ZWaveSerialHandler] - Serial port is initialized 2016-12-25 10:48:16.694 [INFO] [mmandclass.ZWaveSecurityCommandClass] - Update networkKey 2016-12-25 10:48:16.780 [INFO] [ve.internal.protocol.ZWaveController] - Starting ZWave controller ``` ---

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)? > [@watou](#): > > this commit updated nrjavaserial from 3.9.3 to 3.12.1 three days ago. From the [other thread](https://community.openhab.org/t/rfxcom-issue-on-rp3/18282/5): > [@RFXCom issue on RP3](https://community.openhab.org/t/rfxcom-issue-on-rp3/18282/6): > > I got the same problem, I could solve it with installing the “liblockdev1” package on my raspberry. (and using the “RFXCOM USB Transceiver”) The native library nrjavaserial needs it. 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…? ---

I think the groups settings are the same. I’ve seen both liblockdev1 and liblockdev1-dev being mentioned. Which is correct? ( I think liblockdev1 pulls liblockdev1-dev with it.) ---

Tried again, did /etc/init.d/openhab stop (interesting that there was no trace of that in the logs.) installed liblockdev1, rebooted System started, with opehab, I could get the initial screen up on :8080/start/index but after the start initialized zwave , openhab died without a trace. these still remain: ``` pi@homeauto /run/lock $ ll total 12 drwxr-xr-x 15 root root 640 Dec 26 11:15 .. -rw-rw-rw- 3 openhab openhab 11 Dec 26 11:16 LCK..ttyACM0 -rw-rw-rw- 3 openhab openhab 11 Dec 26 11:16 LCK.C.166.000 -rw-rw-rw- 3 openhab openhab 11 Dec 26 11:16 LCK...2648 drwxrwxrwt 2 root root 100 Dec 26 11:16 . ``` Still confused but at least it is repeatable. ---
