Hi all 👋 👋

I am trying to create a flow where it checks for data every single time from an inject node. For example, This is the example flow where it will continuously inject data.  
 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/d/c/dc0a4fdf205635ed7a39e12d162238cbd97d793f.png)

But once one of them stops sending data or injecting for more than 5 seconds , it will trigger and give me and output that says which node fails or at the debug node it will output "Faulty" . Is there a simple or easier way to this function in node red?? if so please guide me

Thanks for the help if possible! ☺ ☺

You can set a different msg.topic for each of the inject nodes. They will then be treated as individual streams.

Hello @ghayne,

Thanks for the Solution. For trigger node, only able to have 2 outputs, so is there a way that can check up to 10 Inject nodes? ☺

Just give each inject node a different topic, it will work for more than 2 inputs, this was only to demonstrate.
