This is a little flow I wrote to use if ever you want to start something to happen for a time then stop.
Very basic things sent with this code.
Note!
0
is to signal START and 1
is to signal STOP
I know it is the wrong way around for most uses, but my needs made it that 0
was what was needed to get things going and 1
was .... optional (could have been anything else too) but to keep it easy, I used that..... used to signal the end of the time.
You can also abort
the timer. But this doesn't just stop things. This code sends the END signal.
I needed this to restore things to how they were before the timer was invoked.
The button's colour and font colour can be changed to indicate things are active.
With a bit of effort, you could even change the text.
(Not needed for my case, so I didn't do it.)
I hope it is helpful.
Oh, P.S.
The flow as is uses a CSS
button. I mention in the code I can't remember where I defined the button and now after I posted the code, I remember (not where I defined the button) but you could use the standard dashboard
button
node and just edit it's properties to accept the different colours for the different parts.
(and also the text if you read the stuff in the flow)
