[SOLVED] OH3: zwave binding Z-Wave Serial Controller Aeotec Z-Stick Gen5 remains offline

If you really have the same issue as described in the 1st post, you have three options. If not, open a new thread as this one here is marked as solved.

Option 1) Use the marked solution (I know it’s a workaround)

I enabled now a workaround using ser2net service dnf install ser2net vi /etc/ser2net.conf deleted the whole content and added only this line 3001:telnet:0:/dev/ttyACM0:115200 8DATABITS NONE 1STOPBIT remctl systemctl enable ser2net systemctl start ser2net Port configuration: rfc2217://127.0.0.1:3001

Option 2) use this workaround (I have not yet tried it)

Ok @HaKuNa and @chris I think I figured out what’s wrong. It appears that openHAB 3.0 requires access to /var/lock. On ArchLinux, this is symlinked to /run/lock, which has permissions set to 755 root root so the openhab user cannot access. /run/lock is considered a temp directory and is configured via /usr/lib/tmpfiles.d/legacy.conf, which Systemd uses to create /run/lock in volatile memory at system boot with those permissions. To override these permissions, I was able to copy legacy.conf to /e…

Option 3) Wait and hope someone will fix it permanently.

This is all handled in the nrjavaserial bundle. OH3 uses a newer version and I seem to recall some changes to fix some issues with locking on some variants of linux.
