Yahoo! Weather for the Soundbridge

Goemon · Sun Jan 13, 2008 11:58 am

Thanks for the information on the display size. So I am a lucky guy with high resolution

I appolgize for elimination of the "local" file from the initial script. It was a good idea and makes use for different languages and locations easier.

Haggis, when you press home 3 times the wget tries to get the actual RSS weather data sometimes it takes some seconds. There are two mesages to the display (please wait, get weather data from Yahoo) maybe thats out of the display to? otherwise you can write a new line into the script, something like "print "checkppoit"; and use this as debug info on your console.

Last thing, look for an other weather service for your location. It must not be RSS. Also most WAP sitesare fine (small files and easy structured HTML) to sqeeze the wheather info from it.

Thanks, Haggis!

One additional change, if anyone is trying to run this on Mac OS X:

OS X doesn't come with the "wget" command installed (at least not in 10.4), but it does have "curl", which has similar functionality. So replace "wget -q -O -" with "curl --silent" and it works fine; no need to install wget.

Also, I changed the line:

       $to1date = substr($1, 0, 2).".".$monname{substr($1, 3, 3)}; # the date reformated: "dd mmm" to "dd.mm"

to

        $to1date = $monname{substr($1, 3, 3)}."/".substr($1, 0, 2); # the date reformatted: "dd mmm" to "mm/dd"

to put the date displayed into the US style month/day; likewise for $to2date.

When I press home 3 times, the display does not change. I know what messages you are talking about, I see them when T4ROKU first gets the weather info. I moved the Y offset so I can see them on my screen, but I don't see these messages (or even a screen clear) when pressing home 3 times.

First time I press home takes me to the menu as normal. Second time locks up the soundbridge for approx 20 seconds. The screen does not clear and no messages appear. After 20 seconds, I can control the menu for a second or two with the remote, then it locks up for another 20 seconds again. This repeats several times, and then the soundbridge works normally. Maybe wget is retrying. I haven't had time to look into it.

I think there's an error in this line to calculate the wind direction:

$winddirection = $direction[ int($1/(360/($#direction + 1))+.50) ]; # the wind direction

If the direction is 350, this is int(350/(360/8)+.50) = 8. The array only has indexes from 0 to 7. I think there needs to be a modulo on this line.

$winddirection = $direction[ int($1/(360/($#direction + 1))+.50) % ($#direction + 1) ]; # the wind direction

A tip that you might find useful. I have made a script my own previously that have the same functionality as "pressing home button three times", but instead uses the on/off button ("double click"). When this is done a menu will be shown. And one of the options is "shutdown music server" which will do "shutdown -h now".

Hi,
first of all thanks for your efforts!!!

I tested Goemon and Haggis .pl files on my two SB M-1000.
Haggis one works perfect.
With Goemon's one i've the problem that i only see half of the information.

I think Goemon's soundbridge has already the new display from the sb Radio (280x32). I think they now produce at roku only one display for the soundbridge m-1001 and the sb-radio, to reduce the production costs.

M-1000 (280x16) all versions
M-1001 (280x16) older versions
M-1001 (280x32) newer versions ???
Radio (280x32) all versions

When i press 3 Times Menu, it works most of the time with both scripts, but not everytime. I'll check that tomorrow.

I've managed to get the script running but not working (the m1001 version of the script) -- let me describe what I'm doing:

I went to http://www.weather.com and gave my location as Chicago, IL. The URL of the page it returned was http://weather.yahoo.com/forecast/USIL0228.html ; I assume the USIL0228 is what I need to enter as the $locationid value in the script.

Everything else is pretty straightforward and noted in earlier posts in this thread:

I set $display to the Soundbridge's IP address.

unitsID is f, direction has the English direction abbreviations.

Because I'm using OS X, I followed the warning (much appreciated!) to change the wget to curl:

$weatherdata = `curl -s -"http://weather.yahooapis.com/forecastrss?p=$locationid&u=$unitsid"`;

And I changed the to1date and to2date lines:
$to1date = $monname{substr($1, 3, 3)}."/".substr($1, 0, 2); # the date reformatted: "dd mmm" to "mm/dd"
(and similarly).

When I run the script, I get:

Is this merely the particular server that the script uses is down, even though Yahoo's weather Web page server is running? Or maybe I made an incorrect assumption about the location ID? (On the off chance the US wasn't necessary, I tried just IL0228, but it didn't work either.) Or can you folks who know your way around scripting spot something else I might've done?

Many thanks not only for any advice anyone might have but to all who've worked on the scripts. It's very cool and I have a feeling I'm not very far at all from getting it running.

Hello,

I get immideate response for the rss feed, but I noticed that there are differnet URL for the feed - the retruned data is the same.

If I go via www.yahoo.com it is:
http://xml.weather.yahoo.com/forecastrss?p=USIL0225&u=f

And via http://developer.yahoo.com/weather/ it is:
http://weather.yahooapis.com/forecastrss?p=USIL0225&u=f

maybe you can try to replace the server name...

Hello again,

I changed the icon drawing procedure a little to improve the speed. it now draws successive white pixel as a line now. this improved speed on my roku by over 50% (I drew all icons one after another and measured the time):

# perl fixicon.pl
start old
Old: 627sec
start new
New: 258sec

I will copy it into the t4roku script at next release. Change is at the botton:

sub drawIcon {
    my $filename = shift;
    my $u = shift;
    my $v = shift;
    my $bits = "";
    my $x;
    my $y;
    my $i;
    my $j;
    my $s;
    my $t;

    open(iconfile, "<$filename") || die "Icon file ".$filename." not found!";
       my @icon = <iconfile>;
       my $cnt = 0;
       my $s2;
       my $help;
    close(iconfile);
    if ($icon[0] eq "P1\n" ) { # continue because its a PBM file
       # read the pbm dimensions
       $icon[2] =~ /^([0-9]+) ([0-9]+)/;
       $x = $1 ;
       $y = $2 ;
       # make a black box before drawing
       $display->cmd("sketch -c color 0");
       $display->cmd("sketch -c rect $u $v $x $y");
       $display->cmd("sketch -c color 1");

       foreach (@icon) {
         $bits = $bits.$_ ;
       };
       $bits =~ s/\n//;
       $bits =~ s/^.* $x $y//;
       for ($j = 0; $j < $y; $j++) {
           for ($i = 0; $i < $x; $i++) {
           $cnt = 1;
           $bits =~ s/([0|1]) //;
           if ($1 eq 1) {
             $s = $u+$i;
                $t = $v+$j;
                while ( ($1 == 1) and ($i < $x-1) ) {
                 $bits =~ s/([0|1]) //;
                $i++;
                 if ($1 == 1) {
                    $cnt++;
                 };
                }
                $s2 = $s + $cnt;
                $display->cmd("sketch -c line $s $t $s2 $t"); # line x1 y1 x2 y2       
           }
         }
       }
    }
}

Thanks danme, the idea for server shutdown is great. On my uNSLUng it does not work with "shutdown -h now" but with "/usr/sbin/DO_Shutdown". I will set this on the to do list :wink:

Hi, Goemon, thanks very much for helping -- I got some time to read up on curl over the last couple of days, and the syntax was wrong (at least for the version of curl installed with my Mac); the - before the URL shouldn't have been there, and once I took it out, the script worked fine. My next project is to put this into cron so it will run just before I get up in the morning (I use my SB Radio in the morning, so the M1001 this is running on isn't used otherwise) and then switch back to the regular display once I've left. Thanks again!

Hello,

The next level :lol:

. Today I have got the last missing part for my project. The USB2Serial adapter (PL2303 chip based) arrived and my digitemp setup on the server works:

# pwd

A problem is that the adapter is USB 1.1 and does not work on my USB 2.0 hub :evil:

. Simply putting the Hub together with the UNSLUNG dist did not work. Anyway I can play and write some more lines in perl to show my local temperature in addition to the RSS data. I will post this here too.

Good night

I had a problem that the Roku become a unresponsive Brick, when I shut down the server which runs t4roku. So here is the solution for a clean killing (based un my uNSLUng server)

Write a new file in /opt/etc/init.d starting with "K" so that ist will be called at shutdown. My file "K80t4roku" contains:

kill `pidof perl t4roku.pl`
cd /public/t4roku
perl cleanroku.pl

If the t4roku is killed only, it will leave your Roku unresponsible...
Make both files accessible with

chmod 711 K80t4roku

The script rokuclean.pl contains the following code

#!/usr/bin/perl
use strict;
use RokuUI;
my $display = RokuUI->new(host => '192.168.123.123', port => 4444);
for my $int ('INT','QUIT','HUP','TRAP','ABRT','STOP') { 
      $SIG{$int} = 'interrupt';
}
$display->open || die("Could not connect to Roku Soundbridge");  
$display->close;
sub interrupt {exit(@_)};
END {
  undef $display;  
}

That works fine for me.
