Enabling / disabling writing data to a file using a dashboard switch node

We in UK also use "Many roads lead to Rome"

NOTE: I recommend the 2nd option in this thread: Cancel inputs for a period of time - #6 by Steve-Mcl - because I can help you with it & it doesnt use contrib nodes.

If you were to use that ↑ demo then you would place the gate in series between the function and file node to block / allow the flow of messages. And instead of injects to control the gate, use your dashboard switch to send the necessary values to "flip" the gate open / closed.
