When a node is being updated I have a trigger for this in the rules engine. I want a notification of this in the email.
The node is however updated several times in 5 minutes.
I only need 1 notification of this.
I first had the idea to compare the node:changedate with site:current-time with 300 seconds diff in a php rule, but then all email is not send as the first email is also within the 300 seconds.
Any suggestion how to solve this?
