Z-Wave unreliable, Zigbee running fine

Hi!

I started using Homey Pro just before Christmas. Everything was running so smooth and smart from the beginning, but since some point in time, my Z-Wave network became unreliable.

I have 62 “real” Z-Wave devices from different vendors and 10 “Unknown devices” which I can not delete. Most Z-Wave devices are from Fibaro. Very often I need to push any buttons in my hone twice or even three times to have devices or flows react. When I look at the Z-Wave network in the developer tools I see many devices with high error rates like 50%, 60% or even 83%.

I created a support ticket at Athom 4 weeks ago but I am still waiting for any response.

I have 17 Zigbee devices, which are running really smooth and without errors! :+1:

Do you have any idea what I can do to get my Homey work as reliable as it did when I started?
How can I get rid of these “Unknown devices”? Could these be the reason for the high error rates?
I you want me to post any logfile, please let me know.

Best wishes,
Ingo

Homey Developer Tools and press REMOVE UNKNOWN NODEs - it might be required multiple times.

Yes, it could. But after removing Unknown nodes, I would recommend restarting Homey and also cut power from all ZWAVE non-battery powered devices.

Thank you for getting back.

I tried to remove the Unknown nodes, but some of them are reachable, I don’t know why?!
So the Remove-Button of the the single nodes still remain greyed out.
I pushed the button “Remove unknown nodes” a couple of times, but this did also not remove any node, Homey responded with “No unknown nodes were removed”.

Is there anything else I can do to remove these nodes??

Maybe just to be sure, can you post the screenshot from your ZWAVE nodes ?

You should push it…wait eg. until status says READY or something like that, then try again…

Please find attached a screenshot of some Z-Wave devices.

I just tried to remove an Unknown node, which is not reachable, but here I receive the answer “ZW_FAILED_NODE_NOT_FOUND” when trying to remove it. :man_shrugging:t2:

For second node which gives back the status “unreachable” I get the message “W_NOT_PRIMARY_CONTROLLER” after trying to remove it…

Is there no way to get rid of these devices??
What about the CLI function of Homey??

What is your current uptime ? Have you tried to restart your Homey ? Please do so and submit screenshot again eg. 5min since reboot… your ZWAVE network doesn’t look good at all.

You receive that message AFTER pressing this button ?
remove

No, after pressing REMOVE on a single node.

You can’t remove this way UNKNOWN nodes I guess. Try to restart your Homey, it helps also recovering the network / mesh.

The uptime is 8 days currently… I will do a restart now and send a screenshot 5 minutes later
I did restarts in the past, but that did not help.

I’m rather wondering what will be the packets counts with shorter uptime, eg. 5min… let’s see, it will not harm.

Please find the screenshots, about 5 mins after reboot.
The error rates are way higher, the Unknown nodes are still there.
However, in the past my feeling was that Z-Wave is working more reliable after some days of running it… and doing some manual “Heal” commands…

Those are not all your nodes, right ? Have you tried to cut the power from them ?

What happens now when you press REMOVE UNKNOWN NODES ?

No, these are just some samples. I have over 60 nodes all in all.

No, I will do the complete power off on the next weekend. Currently it would be a problem for all other family members… :squinting_face_with_tongue:

Still the same message: “No unknown nodes were removed.”

OK, I meant full mesh, not just a sample. Also when I meant cutting the power, it might help just to do partial one, I guess you have power circuits?

Adding zwave devices in “ insecure” mode might help with stability and load on the network.

Had similar issue, but after adding them insecure, all fine
