Hello everybody!  
I need to automatically Enabling or disabling the nodes.  
I have found plugins "node-red-contrib-simple-gate" and "traffic node", but this is not what I want.  
I just need to disable and enable some the nodes.  
I found this information ([Nodes : Node-RED](https://nodered.org/docs/user-guide/editor/workspace/nodes#enabling-or-disabling-a-node)) , but I cannot figure out how to use it.  
core:enable-selected-nodes  
core:disable-selected-nodes

Hi @rapidshe - welcome to the forum.

You cannot dynamically enable/disable nodes in the runtime without deploy a new flow configuration.

The `core:enable-selected-nodes` actions are used in the editor whilst editing the flows.

Why do you need to do that?

I am using a plugin node-red-contrib-homekit-bridged.  
This plugin is needed to create devices in a home kit (apple application for a smart home).

I want to be able to dynamically add and remove some devices from it.

This can be done by enabling or disabling nodes. or the whole Flow. and after that, of course, you need to do deploy.

There is a solution! You can enable and disable the flow! Here is a link to the source: [[Setup Help]: Is there a way to display a message in a NRCHKB node or hide it? · Issue #334 · NRCHKB/node-red-contrib-homekit-bridged · GitHub](https://github.com/NRCHKB/node-red-contrib-homekit-bridged/issues/334#issuecomment-721291246)

Here you just need to insert the ID of the desired flow.
