Hi there, simple question :

How can I trigger a flow every five minutes at perfectly regular time (12:00:00 - 12:05:00 - 12:10:00 - etc) without having to worry about the flow being re-triggered every time I deploy ?

I am trying to create a database that saves data every 5 minutes. For now I'm using the Delay node but every time I deploy for something else it makes a new entry on the DB and restart the 5min delay.

(12:00:00 - 12:05:00 - "Deploy at 12:05:30 / entry at 12:05:30 on DB" - 12:10:30 - etc)

I precise that I'm using a weird instance of Node red provided by QNAP-NAS and I can't choose what to deploy like on a normal Node Red instance. I always have to deploy everything.

Thanks you !  
Nico

Have a look at cron-plus as I think that might form part of your solution.

The default inject node can be set to `interval between times` mode that does just that.
