I have a simple message format question. I have set up an inject node to send 1, 2, 3, or 4 as a string. How do I incorporate a node to send those with out using an inject node? It truly is a s simple as sending a 1-4 when it receives a time stamp. I tried using a template node but I don't think im doing it right.

A flow has to have something to activate it. I't could be a physical button that is pushed or a sensor that detects motion or a sensor that triggers every 5 minutes to read the temperature.

It could also be an `inject` node that is set to only fire off when you press it...or it could be set fire off every 100 milliseconds (or every 2 hours).

But _something_ has to kickoff the flow you put together.

Yes, Im sorry I should have been more clear. I I am going to have a random Number generator set up to a PIR sensor. When it picks any of the 1-4 is will send that number on. How do I send it as a string? Change Node?

I have a half way working flow! How would I define numbers to delete from the change node If I wanted anything greater than 5 removed?

You have confused me. It might be best is you share your flow.  
If you want to ignore any number greater than 5 try the `switch` node

Have you thought instead of having that PIR signal go into a node that generates a random number between 1 and 4 instead, rather than having to delete generated numbers not in that range?
