Hi all, sorry to have to post this but I am defeated. I have been scouring the forum and google looking for a solution to what I want to achieve, I guess being new has limited this a little as I don't always know the correct terms to search.
Anyway, I have a button on my fridge. when I press it, it tells the kids to come and eat. The next time I press it, it tells them to come and eat in a slightly more passive agressive way and so on.
I struggled to come up with a way to do this until I found a forum post about the colour outputs from a function node. So I stole that node and edited it slightly (and I suspect badly).
This works well as it stands, except that the message placement does not reset, each meal time the messages get more passive agressive rather than resetting after a short while.
If anyone has any suggestions how I can return to the first message after say 30 min of the button not being pressed, I would appreciate the advice.
a simplified version of the flow below:

you need to store the last time the function ran, then each time compare that to the actual time.
e.g.
```auto
const colours = [
"Come downstairs, it is time to eat!",
"Food is on the table getting cold! Come and Eat it!",
"I have told you twice already, I expect you in the kitchen in ten seconds.",
];
const reset_time = 30; // time in minutes
/ ****dont change***** /
const old_time = context.get("old_time") || 0; // get last time function ran
let colour = context.get("colour") || 0; //restore last colour or default
const new_time = new Date().valueOf();
if ((new_time - old_time) > (reset_time * 60000) || colour >= colours.length) colour = 0;
msg.payload = colours[colour];
context.set(["colour", "old_time"], [colour+1, new_time]); //store last colour and time
return msg;
```

Fantastic, that seems to work perfectly! Thank you so much!
