Trigger node - how to delay and repeat message?

Thank you all for your suggestions. I know there are a lot of possibilities to solve my problem.

However, the main reason for my post was the fact that the trigger node can currently be parameterized to do nothing, and that makes absolutely no sense from a user perspective.
If that's the intention, then it should at least be clearly mentioned in the documentation. However, it would be better to either remove these settings or change the behavior so that the setting makes sense.
Personally, I would lean towards the second option.
