Hi All,

I've created a flow which is listening to certain alerts and then broadcasts to my Alexa when they come through but I only want the first one to be processed with a 20 minute pause before the next one can come through. I've tried the delay function but this still processes all the alarms but just at a delayed rate.

The source will be inputting a alarm every 1 minute but I only need to know once and then 20 minutes later if the alert is still active. If I set 20 minute delay and during this time I can 19 alarms, all what happens is the will go on every 20 mins 19 times which is no good.

I only want to here the first alarm, wait 20 minutes to see if alarm is still happening, tell me again and wait 20 minutes before reminding me if still active.

I hope I'm making sense.

Please can someone help.

look at the `trigger` node. Set to send original message on 1st message then wait 20 mins then send nothing... Don't extend the timer.
