There are three channels associated with rainfall.
|
||||
There are four channels associated with rainfall.
|
||||
The raw counter from the tipping bucket is provided, the rainfall in the last 60 minutes is updated on each received rainfall and provides the past 60 minutes of rainfall.
|
||||
The rainfall in the previous hour is the rainfall for each hour of the day and is updated on the hour.
|
||||
The accumulated rainfall for today provides the amount of rain for the current date and will reset to 0 at timezone's midnight.
