Hello,  
I'm trying to develop and debug a complex flow and am looking for a simple way to enable or disable parts of the flow (without the disable/deploy actions).

I like the UI of the Inject and Debug nodes, and want something that passes messages if the node is enabled (via a button).

Is there a similar node (with a button) that passes a message if its button is enabled?

alternate question

How can I configure a debug node passthrough a message?

Steve

Have a look at [node-red-contrib-simple-gate (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-simple-gate)  
This should do the trick for you.

The gate node in conjunction with two Inject nodes is the way to do it.

You can't, just wire round it.

Yes, but this will execute the subsequent nodes regardless of whether I'm debugging.

Did you check if [node-red-debugger](https://flows.nodered.org/node/node-red-debugger) fulfills your demands?

Thanks' [edje11](https://discourse.nodered.org/u/edje11) , that pointed me in the right direction.

I prefer not adding nodes, but the answers here and reviewing the node helped me to find my own solution.

You could use a flow context variable and a switch node.

Ah yes, that makes it cleaner.

And to tidy up debugging on your complex flow you can use a link out node.

![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/7/7/779e0edc7d59f405389554ec0d2d3011cd5dc5cb.png)

If you use a global context variable the link in etc can be on a seperate tab. Then to debug at any point you just need to insert a link-out.

Or a subflow gate that can be toggled with a control message inject node, and can be named to lock multiple with same named toggle\_pass subflows environment variable at same time.
