Hi all,  
I need to send a mail every X hours. I was thinking to make it using the inject node that comes by default with node-red. The problem is I have to pass the number of hours to the inject node because it could be different.

How could I do it?

Personally, I would write a simple Javascript function for that easy task and be done with it .... 🙂

However, if you prefer a third-party node, have you looked at?

`node-red-contrib-cron-plus`
