Hi, I’m having some major trouble with my z-wave network. Suddenly things started to become very unstable and I tried to reset a device, but was unable to do so. I already had a couple of Fibaro powerplugs that I had never used so I tried adding these, also without any luck. Checked Developer tools and could see that I had over 25 “Unknown Nodes” and all of my devices were trying to go trough 255-255-255 route. (Sorry for the low quality) [270205158\_10158226199826806\_5454714646224592546\_n|690x342](https://community.homey.app/uploads/short-url/zaxMfkQ5GNKbe2mxA8DSTeIN14v.jpeg) I then tried to reset my whole Z-wave network, and then my entire Homey (😢) Now I have 40 “Unknown Nodes” and I’m still unable to add any z-wave device. ![HgZYLZA](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/a/9aeb8d37bfd990181dca42e8f698bf19efcf9247.png) ![269782625_10158219860866806_5077564156065964204_n](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/8/986d5c6efb7fbafc279771585da4d7e3e1fc7e74.jpeg) Anyone got any idea what’s happening here? ---

Were the reset attempts successful or did you encounter any error messages? If the resets were successful, you should not see this. A reset of your Z-Wave network should result in an empty list. Same as it should be after a full reset of Homey itself. ---

Yes, the reset was done. First all my z-wave devices were removed. When I did the full reset all devices were gone and I had to setup homey as new. No devices but the 40 Unknown nodes Are there ---

Can you remove them by clicking on the 3 dots and select “Remove”?
