Uh... my bad, I miss-read the details. You are right, it's a rainfall per
hour rate.
I think a pre-filter script to convert your hourly rate back into a counter
before feeding it to rrd would be the best option. A little python
scripting would probably do it pretty easily.

Thanks everyone for the answers, especially Alex for the long one. :-)
I will then write my own (window) interpreter for my rain gauge values.
Thanks! MP

No it's not.

Look approximat
A far simpler solution is; it's just a counter that resets every hour.
Provided you set sensible min and max rates, rrd will just see the hourly
reset as a counter reset and record an UNKNOWN rate (NaN) for that 5min
(since rrd cannot know how much rain fell between the reset and the sample
taken
