In one line
Messages meter in 5 KB blocks; connection minutes tick on their own.
What gets missed
An 8 KB publish bills as two messages and a 200 byte publish as one, so padding toward 5 KB is free but spilling past it is not. A triggered rule always meters at least one rule and one action, even if no action fires.

Bills the same way
These services turn exactly the same meters, so what you learn here transfers.
