Devices gone in z-way smarthome after reboot

[perhusaas]

When the unit is rebooted, the devices disappear from the rooms in the smarthome GUI. They come back when i restart the z-way-server.service manually.

The main devices still shows in the z-wave device list, but the configuration menu only has a "rename device" box, all options on child devices are gone.

I can still actuate devices in expert UI, so the network is running.

System:
Chromebox 1 running Debian Buster
UZB with lisence
Z-Way version 3.0.0

First of all please upgrade to v3.1.1 and then if the erro still persists, please provide more info and evidance.

[perhusaas]

Ok, but is 3.1.1 ready for Debian 10.6 Buster? This page says 3.0.0 for debian?

[PoltoS]

Okey, you are right. Doesn't ubuntu version work btw?

[perhusaas]

I updated using Ubuntu 3.1.0, and this problem is gone. 👍
I will try to upgrade to 3.1.1 in a while.

[perhusaas]

That was'nt true after all, i'm still seeing this issue from time to time.
Is there any logs i can look at to find the issue?

[PoltoS]

Please provide logs from Z-Way start to idle state and specify which device is missing. We will check the log for errors

[perhusaas]

Where do i find that log?
All devices are missing..

[PoltoS]

If all are missing, Z-Way has failed to connect to the UZB1. Most probable is that the port changes from /dev/ttyACM1 to /dev/ttyACM0 or vice versa

[PoltoS]

Log is in /var/log/z-way-server.log

Also do dmesg and search for ACM - show those lines and +/- 5 around

[PoltoS]

If thisi s the case, you can use udev to set constant tty name to the dongle

[perhusaas]

That isn't the case, as the devices are there and working in "expert" GUI. Its just the smarthome GUI that is empty.
I use /Serial/ByID to address the UZB so its no problem.

I found the log, but it hasnt happend in a few days. I'll power cycle it tomorrow to test.
