@admin: Many thanks for your idea.

Here is my actual script which calculates the forecast for the next 24h, today and tomorrow. I hope somebody can use it to progress with it.

Code:

require('json') https = require 'ssl.https' appid = 'xxx' lat = '52.436225' lon ='10.42526' azi = '170' hours = '48' format = 'json' tilt = '33' capa = '8' url = 'https://api.solcast.com.au/world_pv_power/forecasts?latitude=%s&longitude=%s&hours=%s&format=%s&tilt=%s&capacity=%s&azimuth=%s&api_key=%s' url = string.format(url, lat, lon, hours, format, tilt, capa, azi, appid) res, code, headers, status = ssl.https.request(url) log (code, status, headers) data = json.pdecode(res) --Fault messages: if not data then   alert('Error converting data')   return end if not res then   alert('Error collecting data')   return end data = data.forecasts -- PV Forecast Calculation*************************************************************************** now = os.date('*t') hour = now.hour i=1 j=2 k=1 forecastsum=0 rest_hour = 24 - hour repeat    forecast = data[i].pv_estimate + data[j].pv_estimate        forecastsum = forecastsum + forecast          -- next 24h      if k == 24 then         forecast_24h = forecastsum         grp.write('43/4/25', forecast_24h)      end      -- today      if rest_hour == k then         forecast_today = forecastsum         grp.write('43/4/26', forecast_today)      end          -- tomorrow      if (rest_hour + 24) == k then         forecast_tomorrow = forecastsum - forecast_today         grp.write('43/4/27', forecast_tomorrow)      end -- hourly forecasts next 24h     if k < 25 then       grp.write('43/4/'..k, forecast)     end     i = i + 2 j = j + 2 k = k + 1 until k > (rest_hour + 24)     -- *************************************************************************************************
