Hello all,

I am trying to add a window on the home page that would display the real temperature outside my home read from my weatherstation.

Using an application called open2300, I am able to read this temperature outside of XBMC. This data is then available to XBMC either in a file or via HTTP (XML, JSON, whatever).

I created an addon that reads this file/url, and this works fine. Now I am struggling to have the skinning engine use this data. I was thinking about running the addon at startup and then store the temperature inside some XBMC global setting. (For the Java programmers out there, this would be the equivalent of System.setProperty("temp","5°C"), which make the "temp" property available to anuthing in the JVM)

I have found that addons can done this with the following label:

Code:
<label>$ADDON[script.cdartmanager 32067]</label>

However in my case, I am not running within the context of an addon.

Any idea? (or any suggestion for a better approach to this problem)?

Thank you.

V.

I found inspiration from existing skin/addon (NextAired and Transparency, actually).

To "put" information from the script:

Code:
self.WINDOW = xbmcgui.Window( 10000 )

self.WINDOW.setProperty( 'MyProperty' , 'hello' )

To read the information from the skin:

Code:
<label>$INFO[Window(Home).Property(MyProperty)]</label>

Issue closed!

Hey, done!

This is what I managed to do.

When XBMC starts, it initiates a thread that will poll the weather every 30 minutes.

Unfortunately the wife does not realize how uber cool this is Rofl

Looks great, and awesome idea. No more running to the window to check the temp meter. Makes me wish I had a weather station. Smile

If it can't be controlled from the sofa, it's not worth having. Wink

Are you going to release it to the public so that others can use it (i.e. me, if I ever bought a station)?

nice job

I'm not going to package this as an addon (no time for this), but I can share the source files.

The data is put in a mysql database using open2300's mysql2300 (nothing to do with XBMC)

I have a PHP page that provides the data in text format to XBMC via HTTP (I already have a webserver for my weather reports, so I used this one instead of messing with mysql in XBMC's python)

PHP Code:
<?php
    define('MYSQL_HOST', 'localhost');
    define('MYSQL_USER', 'open2300');
    define('MYSQL_PASS', '**********');
    define('MYSQL_DATABASE', 'open2300');
    $sql = "SELECT * FROM weather where timestamp = (select max(timestamp) from weather)";

$mysqlCnx = @mysql_connect(MYSQL_HOST, MYSQL_USER, MYSQL_PASS) or die('Grrrr');
@mysql_select_db(MYSQL_DATABASE) or die('Grrrr');
$mysqlQuery = @mysql_query($sql, $mysqlCnx) or die('Grrrr');
$row = mysql_fetch_array($mysqlQuery,  MYSQL_ASSOC);
echo 'date='.$row['rec_date']."\n";
echo 'time='.$row['rec_time']."\n";
echo 't_int='.$row['temp_in']."\n";
echo 'h_int='.$row['rel_hum_in']."\n";
echo 't_ext='.$row['temp_out']."\n";
echo 'h_ext='.$row['rel_hum_out']."\n";
echo 'tendency='.strtolower($row['tendency'])."\n";
echo 'forecast='.strtolower($row['forecast'])."\n";

$sql = "SELECT min(temp_out) as t_min_24h, max(temp_out) as t_max_24h FROM weather where timestamp>" .date("YmdHis",time()-3600*24);
$mysqlQuery = @mysql_query($sql, $mysqlCnx) or die('Pb de requête');
$row = mysql_fetch_array($mysqlQuery,  MYSQL_ASSOC);
echo 't_min_24h='.$row['t_min_24h']."\n";
echo 't_max_24h='.$row['t_max_24h']."\n";

$sql = "SELECT min(temp_out) as t_min_7j, max(temp_out) as t_max_7j FROM weather where timestamp>" .date("YmdHis",time()-3600*24*7);
$mysqlQuery = @mysql_query($sql, $mysqlCnx) or die('Pb de requête');
$row = mysql_fetch_array($mysqlQuery,  MYSQL_ASSOC);
echo 't_min_7j='.$row['t_min_7j']."\n";
echo 't_max_7j='.$row['t_max_7j']."\n";

$sql = "SELECT min(temp_out) as t_min_30j, max(temp_out) as t_max_30j FROM weather where timestamp>" .date("YmdHis",time()-3600*24*30);
$mysqlQuery = @mysql_query($sql, $mysqlCnx) or die('Pb de requête');
$row = mysql_fetch_array($mysqlQuery,  MYSQL_ASSOC);
echo 't_min_30j='.$row['t_min_30j']."\n";
echo 't_max_30j='.$row['t_max_30j']."\n";
?>

Then a script in XBMC that runs at startup (using autoexec.py) and calls the proper URL every 30 minutes then parse it to get the weather data

Code:
# -*- coding: utf-8 -*-

import urllib

import os

import sys

from traceback import print_exc

import re

import socket

import xbmc

import xbmcgui

import xbmcplugin

import time

import threading

CACHE_PATH = xbmc.translatePath("special://profile/temp/")

if not os.path.exists(CACHE_PATH): os.makedirs(CACHE_PATH)

class MeteoThread (threading.Thread):

  def __init__(self, threadID, sleeptime):

    self.threadID = threadID

    self.sleeptime = sleeptime

    threading.Thread.__init__(self)

  def run(self):

    while 1==1:

      print "[MeteoThread] fetching data"

      counter = int( xbmcgui.Window( 10000 ).getProperty( 'Meteo.counter' ) )

      counter += 1

      __myurlopener__ = urllib.FancyURLopener()

      __myurlopener__.retrieve("http://localhost/getdata.php",CACHE_PATH+"data.txt")

      filename = CACHE_PATH+"data.txt"

      file = open(filename, "r")

      lines = file.readlines()

      file.close()

      for line in lines:

        data = line.split('=')

        xbmcgui.Window( 10000 ).setProperty( 'Meteo.'+data[0], data[1].strip() )

      xbmcgui.Window( 10000 ).setProperty( 'Meteo.fetched', 'true' )

      xbmcgui.Window( 10000 ).setProperty( 'Meteo.counter' , str(counter) )

      print "[MeteoThread] fetching data complete (set#"+str(counter)+"), now sleeping "+str(self.sleeptime)+" seconds"

      time.sleep(self.sleeptime)

print "[Meteo] starting..."

HomeWindow = xbmcgui.Window( 10000 )

HomeWindow.setProperty( 'Meteo.counter' , str(0) )

pollingthread = MeteoThread(0, 60*30)

pollingthread.start()

print "[Meteo] started"

This is my very first try at Python, so it's probably ugly...

Then finally in the skin I add the corresponding stuff (see next post)

Nice idea, thanks.
I made a "weather widget" for builtin functions out of it.

I'm no good at python either, been at it a few times but can never think of anything I want to code, so to me it looks great. Hey - if it works, it's all good. Smile
