Help with message handling

[Trying_to_learn]

So far:
I have the basic flow working and all is fine as intended.

It has the capacity to pass all messages or pass the message only if it is different to the previous one.
That way it is only showing changes to the condition. This helps if it is supposed to be only one state and only for very infrequent changes to the other.

Un thought of problem:
It is constantly changing from one state to the other at a fairly sharp frequency.

I am wanting to get something which will see the incoming messages and if they go to the preferred state and stay there for a time: then it sends a signal saying that the fluctuations have stopped.

I'm guessing a trigger node is needed - as I am typing this message.

Definitions:
The frequency of scanning is 30 seconds. (or there about).
I want to see ...... 5 good messages come through before saying all is well.

So.... 5 x 30 = 150 seconds.
I set the trigger node to 160 and all should be good yes?
No, I don't think that will work. Because when the trigger node is reset it doesn't send the other message.

This seems to do the trick
