It's a Lua script.
But forget about the script i amended.
After a closer look it aint working as i intended.
The 60 and 120min forecast are printed but are presenting the 30min prediction.
Need a closer look.

Code: Select all

2017-04-23 17:00:00.403 LUA: Regen verwacht: 0 mm binnen 15 minuten.

So the script seems to be working, yet my device (Rain expected) isn't updated. It still says 'Hello World'.. How can I get this working?

I think its because it is an "rain radar" so it doesnt show the rainfall at the moment, but only in future, like IS it gonna rain in 30 minutes, and if yes how much..
lat & lon correct?
What does the log says?

Which script are you using, could pass it here?
In order to see how you set it up.
Because i have the feeling that you have setup the rainfall below 60 while the round number is setup to 1 decimal or less behind the comma.
Meaning the script says "0.003mm rain expected" but your widget gets updated to 0 decimal behind the comma.

local RainTextIDX = 113   -- your domoticz text device
debug = false -- enable or disable debug output
tempfilename = '../var/packages/domoticz/scripts/lua/tmp/Rain.tmp' -- be sure this is in the correct map, and give it chmod 0666
totalrain = 0
rainlines = 0

function IsItGonnaRain( minutesinfuture )
   url='http://gpsgadget.buienradar.nl/data/raintext/?lat=51.86&lon=4.41' -- this is important!! change the lat and lon to your needs!!
   if debug then print(url) end
read = os.execute('curl --connect-timeout 5 -s -o '..tempfilename..' "'..url..'"')   file = io.open(tempfilename, "r")

   while true do 
      line = file:read("*line")
      if not line then break end
      if debug then print('Line:'..line) end
      linetime=string.sub(tostring(line), 5, 9)
      if debug then print('Linetime: '..linetime) end

      linetime2 = os.time{year=os.date('%Y'), month=os.date('%m'), day=os.date('%d'), hour=string.sub(linetime,1,2), min=string.sub(linetime,4,5), sec=os.date('%S')}
      difference = os.difftime (linetime2,os.time())

      if ((difference > 0) and (difference<=minutesinfuture*60)) then
         if debug then print('Line in time range found') end
         rain=tonumber(string.sub(tostring(line), 0, 3))
         totalrain = totalrain+rain
         rainlines=rainlines+1
         if debug then print('Rain in timerange: '..rain) end
         if debug then print('Total rain now: '..totalrain) end
      end

   end
   file:close()
   
   averagerain=totalrain/rainlines
   return(averagerain)
end

function round(num, idp)
   local mult = 10^(idp or 0)
   return math.floor(num * mult + 0.5) / mult

commandArray = {}
   minuten=15

This is the script I'm using

   if debug then print(url) end
read = os.execute('curl --connect-timeout 5 -s -o '..tempfilename..' "'..url..'"')   file = io.open(tempfilename, "r")

      difference = os.difftime (linetime2,os.time())

      if ((difference > 0) and (difference<=minutesinfuture*60)) then
         if debug then print('Line in time range found') end
         rain=tonumber(string.sub(tostring(line), 0, 3))
         totalrain = totalrain+rain
         rainlines=rainlines+1
         if debug then print('Rain in timerange: '..rain) end
         if debug then print('Total rain now: '..totalrain) end
      end

   end
   file:close()
   
   averagerain=totalrain/rainlines
   return(averagerain)
end

function round(num, idp)
   local mult = 10^(idp or 0)
   return math.floor(num * mult + 0.5) / mult
end

commandArray = {}
   minuten=15
   RainPrediction = IsItGonnaRain(minuten)
   RainmmHour=10^((RainPrediction-109)/32)

      RainPredictionText=('Voorlopig blijft het droog!')
   end
   
   commandArray[2] = {['UpdateDevice'] = RainTextIDX .. '|0|' .. tostring(RainPredictionText)}

return commandArray

At the moment the script is spewing out errors '2017-04-29 19:20:01.901 Error: EventSystem: in Regen Verwacht: [string "local RainTextIDX = 113 -- your domoticz te..."]:13: attempt to index global 'file' (a nil value)', so I stopped it for now.
