Due to some problems with an Aeotec sensor, i ended up with an “unknown node” in my Z-wave network again. I know there was a removal button in a previous version, but that has unfortunately disappeared.  
However, on the bottom of the page i found this:

![Homey%20remove%20nodes](https://us1.discourse-cdn.com/flex025/uploads/athom/original/2X/f/f11e20d93068e5b4a5b334c1504a4eb035f9d972.jpeg)

I don’t have the courage to press it because i am afraid it will remove all devices.  
Does anybody know what this option does?

No remove option in the developers section?

Not with the “unknown node” entry, no. I saw it last week with a device that didn’t respond and expected it also with the “unknown node”. The shown option is present at the bottom of the developer page but i am very afraid to use it…

Once you press it, it will just wait for you to put any node in exclusion mode. Then it will remove that node only.  
I did all day long today removing 48 unknown nodes. With perfect success 😀

P.S. If your node is faulty and cannot be put in exclusion mode, then I don’t think that button will remove it…
