Im taking in sensor data and displaying it with gauges. I use a switch to display a value on the gauges or the string "disabled". The flow has 4 inject nodes with 4 exec nodes that all goes to the IOT hub node for adding data to the database.

My probelm is: how can i stop an individual sensor thread from passing data to the exec node(node that sends data to the command line for retrieving a sensor). i dont want the flow to stop i just want the node to stop sending data to the next node based on the condition wheather the data is the string "disabled" or a number

I think you need to look into one of the logic or boolean gate nodes.

This is one of the newer ones, but I've not used it.

Or possibly the simplest is to use node-red-contrib-simple-gate. Insert that into the flow you want to break and all you need to do is send it the appropriate commands to block or allow the flow.
