What exacly is "rain"

[andreaskoerber]

I understand that the data point "rain" now delivers a "current" value.
But since it does so in mm, there needs to be a timeframe specified. So what exaclty is given as "rain"? ist it the current amount of rain in mm, extrapolated to a day / an hour?
Is it a measured value - or a prognostic one (e.g. extrapolated to "within the current/next hour/day" or so?

There is only live data in this Adapter and some historic like last hour and yesterday

"rain" shows the current status of this hour

"rain_lasthour" the last hour and so on

the unit is milimetres per square metre over the time parameter in the data point (current hour / day / yesterday / last hour)

[andreaskoerber]

Thanks! So "rain" ist mm/m² within the actual hour "so far", i.e. since the last full hour?

[backfisch88]

I think it's during the last 60 minutes

just look at this Station for example... there only stands "1 hour"
https://weathermap.netatmo.com//?zoom=8.397804940368959&type=rain&param=hourly&stationid=70%3Aee%3A50%3A58%3A96%3Aee&maplayer=Dark&lang=en

Ok, thnks.
What, then, ist "rain_lastHour"?
a. the sum of now-120 min: now-60 mint - calculated anew each (full) minute?
b. the value of 60 minutes UP to the last full hour? - calculated anew each full our?

If it is the latter and "rain" ist sum of all minuted from (now-60min) to now, then one may not add "rain_lastHour" and "rain" etc., because they overlap and revent rain would be overweighted.

Where can I fond the exact definitions of the values the service provides?

[backfisch88]

I think A
so now -120 min to now -60 Min

dont know exactly cause the Adapter only parse the data from Netatmo

[andreaskoerber]

That's why I asked, whether there is some more exact info available. I don't find it there, either.

I interpret "rain" as rain of the last 60 minutes
and "rain_lasthour" as rain of the 60 minutes BEFORE "rain".
