Kobo Wifi Weather Forecast

Sorry about the permission denied, I forgot to set it as public.

I really don't know why it can't load the font file. I'm looking into it.
Does it work if you change the font-loading lines in weather.py to use a default font?

tiny_font = pygame.font.Font(None, 18)
small_font = pygame.font.Font(None, 22)
font = pygame.font.Font(None, 40)
comfortaa = pygame.font.Font(None, 60)
comfortaa_small = pygame.font.Font(None, 35)

Yeah, I guessed about the file permission thing.

I lied in my last post, I can't leave anything alone until it's working...

It looks like it can't load the TrueType fonts. When I converted them to otf format and used those instead it worked. Then I just had to copy full_update from .python into the weather app folder (or change line 363 in the weather.py script to point to it) and it worked perfectly! Presumably full_update looks in the current directory for a file called image.png and blats it to the display?



Thanks ever so much for this. Now I've got it working I'm going to make an astronomer's version, possibly based on data from 7timer.com.

I can't quite believe that the Kobo can run Python and pygame natively - that is so cool!

Great! Yeah, I misplaced full_update. It was supposed to be in the same directory as weather.py.
And that's weird that TTF files don't work...

Pygame is actually drawing directly to the Kobo's framebuffer, full_update just tells the system
to update the e-ink display.

Edit: I've updated the Kobo Touch installer to use OTF fonts, as well as placed full_update
where it needs to be.

Fantastic work, I was able to get the weather display working on my kobo wifi easily! I''m now working on making it display some custom data of my own. How did you edit the python file during development? vi is such a pain to use, is there some easy way to get nano (or similar) running on the device?

[PeterT]

It could be worse... could be emacs rather than vi, or teco (but not sure teco ever got ported from DEC).

[jkgeyti]

Would it be possible to make the home button restart the Kobo? This way, I can add a link in ikarus9999's plugin to the weather-app, make it kill nickel and run, and still be able to "get back" to nickel by restarting the device using the home button. It's kind of a hassle that you have to telnet into the device to reboot it now.

Since the script uses pygame, I wrote and ran the code on my computer before putting it
on my Wifi. But if you'd still like to have nano on your Kobo, you could try downloading
and extracting this debian package to your Wifi.

Absolutely. I've set up something similar on my Wifi so I can start or stop nickel and
the weather display by pressing the back and home keys at the same time.

The easiest way to do this would probably be to start a "listener" script when you start
the weather display. Here's a python script that waits for the home button to be pressed
and then restarts the device:

import struct
from subprocess import call

buttons = open("/dev/input/event0")
format = "iihhi"
key_event = buttons.read(16)

running = 1

while running:
        
    (key_time1, key_time2, key_type, key_code, key_value) = struct.unpack(format, key_event)

    # Home button.
    if key_code == 102:
        if key_value == 1:
            print "Home button pressed"
            # Restart the device.
            call(["/bin/busybox", "reboot"])
            
    key_event = buttons.read(16)

Then all you have to do is point the plugin at a script that starts both the listener and the
weather display:

#!/bin/sh
killall nickel
cd /mnt/onboard/.apps/koboWeather
python listener.py &
./autoupdate.sh 
python weather.py

I've added a few bits to the display routine in my copy to make it run sensibly on Windows as well as the Kobo (though I haven't tested it on the device yet). I intend doing all the development under Windows then hopefully copy it across and off I go.

Sure enough, I'm now up and running. Thanks so much for doing this - it's a great hack!

Which plugin are people using on the Wifi? All the plugins I could find on this forum seemed to be for the Touch, not the Wifi.

(I've got firmware 1.9.10 which is the latest as far as I can see)

There is no plugin for the Wifi, though it might be possible if someone wanted to give it a shot.
What I've done on my Wifi is set up a listener that starts on boot and waits for the "back" and
"home" buttons to be pressed at the same time, and then starts either nickel or the weather display.
I'll upload the script as soon as I have time.

Hi,

First of all thank you for such great development. I bought a Kobo just for that, and now I have a fancy weather display

As a newbie, I have no idea about python, but I sure can follow instructions LOL, I have some questions regarding the weather software and Kobo:

1- After I setup the weather.sh with my latitude and longitude I went to worldweatheronline.com's website to check the data, turns out the temperatures on kobo are not the same that the ones on the website (using same lat/long). since this is my first day I will keep running weather.sh for a few days to compare data. Is that a reason why the info is different????

2-Is that a way to avoid kobo going to sleep, so I can have the weather display on all the time????

3- I understood kobo's OS is debian (or debian compatible, right??), if that so would be possible to install a webserver on it (I was thinking about using kobo as a python learning platform), for web development using python.

4- Is that a way to start weather.sh directly from kobo and not with telnet??? I saw something about this here but I have no idea how to implement (need some help).

Thank you again one more time

I too would like to be able to set this up and forget about it.

If it's connected to a power source, will it stay awake?

Fantastic project BTW.

I'm not sure why that is. I've noticed that sometimes it seems to be off, but other times it's fine.

Yes and yes. If you run the command "killall nickel" from a terminal, your Kobo will not
go to sleep. To start the weather display without telnet, install this package on your Kobo.
You can then switch between the weather display and the normal Kobo interface by pressing
the Back and Home buttons at the same time (this will stop your Kobo from sleeping as well).

The Kobo runs Linux, and most debian packages work just fine on the Kobo once you
install all the necessary dependencies, which is the hard part. I know nothing about
setting up a webserver, but it should be possible.

It will. Or you can use the installer I linked to above.

[pcapelo]

Hey Kevin,

Thank you very much. I couldn't ask for more.

Everything its working and I am now running some battery test to figure out how long it will last keeping kobo on all the time and updating weather every hour.

Again, I really appreciate your work and dedication

cheers
