weather forecast

[DeepB]

Hello,

I would like to use the weather forecast for the current day in a Lua script.
Anyone doing this? Can anyone point me in the right direction how to do this, or even better is there a tutorial?

I found the wiki page on forecast.io, unfortunately it seems I only get the current values.

Thank you
Daniel

I'm using WU to get what the weather is after 4 hours.. this way I can adjust underfloor heating setpoint.
Only problem is that it freezes domoticz while its doing http call on lua script. So its not the best way.
I think best way would be to run separate script that collects needed data to file and read from that in lua script.

for this you need to install io, socket.http and json lua libraries.

Code: Select all

function getWUForecast(hoursToSeek)
  io = require('io')
  http = require('socket.http')
  json = require('json')
  
  b, c, h = http.request("http://api.wunderground.com/api/YOUR_API_KEY/hourly/q/LAND_CODE/Location.json")
  -- print("Response status: "..c) -- status.. should be 200
  local lua_value = json:decode(b) -- decode json response to lua table format
  
--   print_r(lua_value)
  
  resultTable = lua_value["hourly_forecast"] -- contains datetime and temp values
  result = resultTable[hoursToSeek]["temp"]["metric"]
  hour = resultTable[hoursToSeek]["FCTTIME"]["hour"]
--   print("Hour: "..hour.." Index: "..hoursToSeek.." Value: "..result)

  return result
end
