Hey I have a problem removing one of my “unknown nodes”. In developer I can send basic on, off, test frame and heal, everything works, I can see it turn on and off only when I do remove it just says “ZW\_Failed\_Node\_Not\_found” … which is weird. I need to remove it to re-add it so I can use it. any ideas? ---

So I had to actually disconnect the node in order to remove it in developer, I figured I should be able to remove it without it being powered off. ---

how do you use the ‘remove any node’ function? I slo have a random non-functioning node that I can’t get rid of. I am worried that if use the ‘remove any node’ incorrectly it will remove something it shouldn’t or even remove all my nodes. Can someone advise me please? ---

> [@Daniel\_Esland](#): > > how do you use the ‘remove any node’ function? You have to follow the manufacturer instructions, they differ, in this case, it was a Qubino device. Qubino devices can be Included or Excluded by power OFF wait 1 minute, activate REMOVE ANY NODE and then power-up the device you want to remove. For other devices read the manufacturer instructions. ---

problem is I don’t know what the device is or was, it just says unknown in the topology. ---

Did you also try this Remove? ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/2X/d/ddaff7d282773fc733b77c5fe313cf849fc3afc3.png) After this, refresh the screen, otherwise it is not updated all the time. ---

I’ve noticed now that if you first try ‘Heal’ and / or ‘Test’ the 'Remove option becomes available and then you can remove your zwave device. So I managed to get rid of some unresponsive zwave devices!
