No, that’s not possible.

As far as rainfall is concerned, you need to decide what you want before you start coding.

I use a rolling 1 hour and 24 hour values for my weather station, as described here:

Rain gauge - ESP8266 Devkit - Blynk

I guess it depends on what you’re trying to achieve. As I said before, I want to see rainfall in millimetres over various time periods - the last minute, rolling 60 minutes, rolling 24 Hours etc. For that reason I use arrays and write the values into the arrays. Take the rolling 60 minute total as an example of how I do this… I use a variable to store the rolling 60 minute total and a pointer to tell me which array element to write into. Once I’ve run for 1 hour, all the array element are po…
