I have been struggling with this issue for over a month now and short of a reinstall of Ubuntu from scratch at I’m at loss to to why this is happening. For the past month or so, Whenever I do a reboot of the machine, I’m am told the Controller is offline. And the only solution I have come up with …

Did you add the libraries mentioned in this thread: https://community.openhab.org/t/oh2b5-and-dev-ttyacm0-z-wave/18783/25

I am not certain this would make a difference if the issue is port naming. @ptmuldoon I am running a similar configuration to yours, but do not have this issue. My device always comes up on ttyACM0 on any reboot or power cycle, however, I can replicate the issue you mention if I remove the Z-Stick a…

for months I am running OH2 now. Today I upgraded to @chris zwave snapshot from yesterday. Since then I get that error and nothing helps to get the stick again when I do ls /dev/tty* I can see there is still the ACM0 8:44:36.107 [INFO ] [ing.zwave.handler.ZWaveSerialHandler] - Connecting to seri…

well what I did this morning was: uninstall ZWAVE 2.0 via PaperUI install ZWAVE 2.0 via PaperUI restart OH I did not check log if automatically any dependencies were triggered

Yep - so as I said, I think it will have installed the new serial library as well and that will explain your problem it seems. To add - dependencies are always loaded - otherwise it won’t work :wink:

Anyword on when to expect the next build? I apt-get updated and upgraded yesterday but still had same issues with ttyACM0.

Please wait for the next build and then try again - the serial lib change has just been reverted.
