Can anyone advise how best to process the input from a rain gauge?

I have a rain gauge connected to an Wemos D1 - it’s counting pulses and uploading the data to my emoncms installation.

Logging the input, I get a feed of an ever increasing count, but I’m struggling to convert that to a usable “rain/hour” feed.

The processing I’m doing to the input is as follows:

1. Log to Feed (rain\_raw) // this accumulates nicely
2. Rate of change // flatlines
3. Allow positive // incase the Aurunio resets
4. x (0.36128564) // conversion for my tipping bucket
5. Log to Feed (rain\_60s) // flatlines

What am I doing wrong?
