Maybe along the same vein as a recent question about `MQTT` nodes and the best way to do something.

I am getting these weird messages - again. ☹  
Daily at about 05:00.

The only thing that happens at that time is the machine's check how full their USB stick is.

This is done/triggered by a signal that happens at mid-night and a 5 hour delay.

So my question is this:

Is it _better_ to have a simple `NEW DAY` signal that a lot of things use and for this routine, add a 5 hour delay.

OR

Just have a node (be it `inject` or `cronplus`) that makes a message at 05:00 daily?

If your device restarts anywhere between 00:00:01 → 04:59:59 your 5hr delay will not be triggered.

Better off using a schedule for 5am (be that an inject, cronplus or other)

Thanks.

I'll go and apply it now.
