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! 👍 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 ---

> [@prahn](#): > > How can I get rid of these “Unknown devices”? [Homey Developer Tools](https://tools.developer.homey.app/tools/zwave) and press REMOVE UNKNOWN NODEs - it might be required multiple times. > [@prahn](#): > > Could these be the reason for the high error rates? 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 ? > [@prahn](#): > > I pushed the button “Remove unknown nodes” a couple of times, 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. 🤷🏻‍♂️ ![Bildschirmfoto 2025-03-11 um 19.57.49](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/6/f/6f3e52a23ff771d3e90dbc3fed7269408b840716.png) ---

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. > [@prahn](#): > > 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. You receive that message AFTER pressing this button ? ![remove](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/2/1203bff87f5e1ccd3477bd740a074b9aa02d877a.png) ---

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… ![Bildschirmfoto 2025-03-11 um 20.17.11](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/4/2477994a1d289c63a2aecee4bfbc5ba993c4a29d.png) ---

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, I will do the complete power off on the next weekend. Currently it would be a problem for all other family members… 😝 > [@Sharkys](#): > > What happens now when you press REMOVE UNKNOWN NODES ? Still the same message: “No unknown nodes were removed.” ---

> [@prahn](#): > > No, these are just some samples. I have over 60 nodes all in all. 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
