OZW stuck on "Starting Z-Wave Network... This may take a while depending on the size of your network."

In the process of doing a rebuilt of my Home Assistant config, and out of nowhere my Z-Wave Network Management page now renders the following message:

I was not doing anything with ZWave prior to this, and I did not pull down any HASS-related update. It started after a reboot.

My existing, successfully configured ZWave devices are functioning properly, meaning I can interact with them through the WebUI, but I cannot do any other ZWave activities such as adding a new device.

The last 2000 lines of my OZW log file can be found at the URL below. Any ideas?

How many zwave devices do you have?

Right now I have ~10. Primary ZWave Plus, and all hard wired (no battery).

Before my tear down and build up, I was probably pushing 25, with the delta being a few plugs and the rest battery. But, I haven’t attempted to pair any of those yet.

Hard to say what’s going on, I don’t use the docker version of HA, but it’s almost like it’s unable to find the device configuration XML files for openzwave.

Does it ever finish starting the zwave network?

I’m so confused.

I left home for a while, and upon coming back to the WebUI I was presented with a “Network Stopped” message and an option to click “Start Network”. I did that.

A little while later, I came back and the status was blank. There was nothing in the top of the ZWave page. It was like a blank Lovelace card. Weird. Rebooted.

Went to the ZWave page. “Network Stopped” and " Start Network" again. I come back later, and all I have is the ZWave stick listed. OK…it started over for some weird reason. I start thinking about the reset process for the existing devices. I decide to reboot.

I log back in, and now everything is back, with a couple of dead nodes to boot.

No clue what’s going on and if what I’ve got going now is stable. Will play around and report back.

Did you remove or disable the modem manager in your Ubuntu host OS? It is described in the docs for Z-wave. For me, this solved similar issues with z-wave between HA restarts.

Has anyone been able to resolve this? I’m having this exact same issue, and it’s not going away even after removing ModemManager. Tried running homeassistant on docker and venv, same results.

Nodes usually do respond, but there is a lag to it. Also, since the network is not listed as ready or started, I can’t add or remove nodes, heal the network or do anything else.

I see the same symptoms as listed above. Huge OZW_Log ( about 2GB)

I have tried different boards, an odroid xu4, raspberry pi 3b and 4. All end up with the same issue.

Any ideas would be appreciated.

Thanks

For anyone else having this issue, I have filed an issue with the HomeAssistant backend project where I documented a possible temporary workaround for this.

See https://github.com/home-assistant/home-assistant/issues/26727

Hopefully this gets resolved some other way soon.

Still no news on the issue :frowning:

Unfortunately nothing yet. I’m still having to drop to the container and poke around pyozw_shell until homeassistant detects z-wave is up and running. Seems that it’s a hit and miss now. Sometimes it comes up by just running pyozw_shell. Sometimes it takes forcing an error in that program.

The only annoyance I have with this right now is that pyozw_shell requires a terminal, so I can’t just automatically launch it and automate the workaround.

Hopefully somebody comes up with a solution.

So, after months of testing, I am not convinced this is problem with homeassistant or openzw, although homeassistant-openzw could and probably should catch this and offer a way out of this loop.

In my case, it appears to be a bad node. It took a bit of time to figure it out but I think I found the culprit. I have an Eaton RF9501 that appears to be mad. As soon as I add that node to the network, it starts flooding OZW_Log.txt. Looks like at some point during the query stage it enters a loop of some kind and it continues to flood the network with traffic.

I noticed that as soon as I remove this node, the traffic slows down and the network functions as it should

Anyone having this problem should try removing their nodes and add them back up while monitoring OZW_Log.txt. You should only see a little bit out output there when you add a node. If you add one and you see lots and lots of output being logged, that node is probably your culprit.

Even though I dont think this is a homeassistant or openzw issue, I think either or both of these projects should do something to detect this issue and raise some kind of notification that says there may be a problem with node X

I would like to see a notification and maybe a suggestion to exclude a node that has gone mad.

I would also point out that this is the 2nd switch that has gone bad on me. I also had an Eaton RF9540 that starting flickering the lights, so it may just be that Eaton is producing bad z-wave products. I have had better luck with Leviton switches.

Hope this helps anyone else having this issue.

Hi,

My Starting z-wave network loop since few days, but z-Wave network work perfectly.
However, I don’t add new module or manage network.

Do you have ideas for help me please?

Oddly, Z-Wave Node Management dropdown list is complete with my nodes :

Could you tail -f OZW_Log.txt and see if it’s at a standstill with occasional output showing up when you trigger some stuff or does it constantly show output scrolling through the screen?

Here is the result of the order tail -f OZW_Log.txt, it seems right, do not you think?

root@homeassistant:/usr/share/hassio/homeassistant# tail -f OZW_Log.txt
