To do so, the app just sends a ConfigNodeReset message to the node&#39;s unicast address, which works perfectly if the node is reachable.

As far as I know you can remove the node in the list by just swiping left on the node. It wont reset the node though.&nbsp;</p> <p>2. The &quot;blacklisting&quot; process is defined in the spec.&nbsp;Please read the&nbsp;3.10.4 Key Refresh procedure section in the Mesh spec.&nbsp;</p> <p>So basically you trigger a key refresh procedure to all the node that you want to retain to the network and leave behind the node you want to remove from the network. Regardless the node(s) you want to remove is active or not it will not get the key to communicate in the network after the new network key is activated.&nbsp;<br />However our mobile app doesn&#39;t offer this feature yet. So if you want to do keyrefresh you need to do it from an embedded Provisioner or modify the app to do this feature.&nbsp;</p><div style="clear:both;"></div>
