Transform total rain data

[theMoe]

Hi,

I use a rain gauge from auriol to collect rain data via rtl_433 repo. The sensor sends only total rain data in mm since last hardware reset. I would like to break it down to at least daily mm of rain. In this case I would need some history rain data.

Do you have any idea if this is possible just with mqttthing?

My basic idea would be look for historical data and calculate the difference.

Bye

Moe
