That's why I'm asking about calculation, because i just don't know how weewx works (until your answer).
I'm using FileParser driver with pool interval of 10 seconds. My "script" grooveweather also generate this text file every 10 seconds and rain information is cummulative from the entire day (I'm guessing, looking for the code). You said that weewx doesn't use rain value for 60 minutes......but using this data (rain in the last 60 minuts, from my driver) in rainRate looks right on report page (again, I'm not sure because I can't test/measure). My archive time is set to 300 seconds (5 minutes). Since my 'driver' generates report every 10 second's, I can't see how I would out rain for the last 5 minutes and then reset this data. The problem is not coding, but the syncronization between '5 minutes' from weewx archive and '5 minutes' in driver code :( Em segunda-feira, 17 de setembro de 2018 09:26:24 UTC-3, Jonis Maurin Ceará escreveu: > > Hi. > Is possible to automatically calculate rain total?! > > I'm using generic cheap instruments (sold on ebay) with GrooveWeather Pi ( > https://github.com/switchdoclabs/SDL_Pi_GroveWeatherPi ). > I'm writing values to text file and reading in weewx using file driver > (customized). > > Rain rate looks working fine: > f.write('rainRate=' + str((rain60Minutes/25.4)) + '\n') > > The value looks correct (about 1.2mm/hour for now).
