inkycal's Issues

Remove hardcoded directory

Since the directory cloned is "E-Paper-Calendar-with-iCal-sync-and-live-weather", it makes no sense for it to expect this to be at "/home/pi/E-Paper-Master".

One can refer to files from his own directory and relative paths.

Using a webcal calendar with the software

I have an "abfallkalender" - some app creates a calendar with the days of garbage here in Germany, which you know how it works.

As this thing creates a calendar, I shared it from iCloud, and it creates a webcal link. As this is just the garbage, here is the example URL:

Link as webcal

If you just paste the webcal url, it fails:

Traceback (most recent call last):

If you change the protocol to http, it downloads a normal ics file. This file is not readable by the ics module being used here:

So, I took the public link and imported into a google calendar, which I shared:

[https://calendar.google.com/calendar/ical/lmnhsglq59s57uj8bi8jlgjl15psjp0n%40import.calendar.google.com/public/basic.ics](public version)

This works. And I love the new version.

Screen keeps blank with v1.7.1

Hello,
thank you very much for the update.
Unfortunately my screen remains white.

It works with the old 7.5 display, Waveshare 7.5 Inch E-Paper Display Hat(B) Module 640x384 Resolution

At startup the screen flickers only briefly, but the calendar does not appear.

Event-Icon suggestion

It's basically impossible to tell the difference between a day with an appointment and the current day on the black and white display. The current day's border is slightly bigger (as it goes around the appointment), but that's it.

Suggestion: make it dashed on b/w displays.

Bug reports for release v1.7.1

Bug reports

Here you have an option to chat about the Inky-Calendar software (v1.7.1) with the author (me) as well as other users from the community.

This issue is mainly intented to help identify bugs/errors/problems in the software. Once something has been reported, I'll try to take care of it as soon as possible.

P.S: Please remember to be nice :)

Auto-start issues (related to python3.5)

The calendar didn't auto start at boot. I installed supervisor as described in the wiki, but the new default version for python seems to be python3.7.

Suggestion:
Change Line 257 in Installer-with-debug.sh from
command = sudo /usr/bin/python3.5 /home/pi/Inky-Calendar/Calendar/E-Paper.py to command = sudo /usr/bin/python3.7 /home/pi/Inky-Calendar/Calendar/E-Paper.py

Everything else works like a charm, even for my Nextcloud Calender. Thank you!

Typo in file name

Separator is written seperator in calendar/other/en

Incompatible version of python-dateutil

Description
Exception "RRULE UNTIL values must be specified in UTC when DTSTART is timezone-aware" in modules\inkycal_icalendar.py:65:

except Exception as e:
    print('Something went wrong while parsing recurring events:' + str(e))

Reason
ics is not compatible with dateutil 2.7+.
Also see https://github.com/pimutils/khal/issues/767[https://github.com/pimutils/khal/issues/767](https://github.com/pimutils/khal/issues/767)

Solution
Downgrade to dateutil 2.6.1 which is the latest working version version.
Add python-dateutil==2.6.1 to requirements.txt

Feature request: Add support for more E-Paper displays

Hi everybody,

Great work with the software!

is it possible to use the Inky-Calendar with the new Waveshare 7.5 inch with a higher resolution (800 x 480)? I tried to change the libraries without any success.

Thanks in advance.

Uninstalling the software

Please extend the installer script with an option to uninstall your programm. Or maybe just add a step-by-step guide on how to uninstall it.

Merging with 9.7 screen E-ink repo

@aceisace, wouldn't it be too insolent to ask you to add 9.7 E-ink screen support for your project.
I'll promise to take care of testing part :)

Announcements (archived)

This is a view-only Announcement issue. It‘s intended to inform about news, important updates and bug-fixes.

Feel free to follow this issue if you‘d like to hear the news about the development of the Inky-Calendar software.

Calibration of black/white screens - was it updated?

Does it need an extra step of "red" calibration?

The code looks like it takes forever to go further.

Weather forecast

You know how I enjoy this project. And to make it even more useful, my suggestion is that the weather should show the conditions for the rest of day instead of the current conditions (after all, we can just look outside for the current conditions).

The rationale is: "should I take an umbrella? Do I ride the bike or the car?"

Missing multi-day events on agenda view

Describe the bug
Multi-days

Steps to reproduce the behavior:
(see screenshot).

There's a multi-day event from march 4th to march 6th, and I see events before and after that.

I can provide an example ics file if required. The Public URL for a copy of it is at webcal://p33-caldav.icloud.com/published/2/MTMxNDQ2NDAxMzE0NDY0MIs4JThLcd2nh4XXItgMUl_Pbg-xF525wLAyhd9OhrAGTB2SWSagUS6Otcajnrjc8ILuXs_9ilCXzUPvlUqFg-g

Expected behavior
To see an event which is between march 4th and march 10th. And there are multiple events on the 10th which don't show on the list.

Additional context
That's the latest pull from GitHub.

Plus, there's like an inch of empty space at the bottom. Is there some bad config I've done?

Installer points to incorrect location of main file

Hello,

I just wanted to tell, that the path to start the application is wrong in the readme.
See the image below:
Instead of
"python3 /home/pi/Inky-Calendar/Calendar/inkycal.py"
the correct path is:
"python3 /home/pi/Inky-Calendar/modules/inkycal.py"

(Looks like the files were reorganized at some point?)

Looking forward to test on the new display, once it has arrived!

All the best
Chris

Text also needs to be fixed in monochrome displays

Thing is, it's not just the bitmaps which need to be converted for 2-colours. Look at the missing month:

Support for 2-Colour E-Paper Displays

Hello

In the pictures some of the writing is red, but my E-Ink Display can not display this color. It can only show black. How can I change the corresponding color icons to black so that they are clearly visible on the display

No module named ics

The new version reads ics files as well (I was trying to do so as well).

However, it's not clear which ics version you are using (there are many of those).

I haven't found it on the documentation, either.

Invalid Alarm Action

Hello,
I have the newest software, the new version looks great, I love that I can now see the upcoming calendar items and the new layout is nice!

I am however struggling with getting the iCal feeds to work. Any of my private ones appear to generate messages like below. Do you have any ideas on how to stop these?

If I grep the ICS I see the following actions:

ACTION:AUDIO
ACTION:DISPLAY
ACTION:EMAIL
ACTION:NONE

Looking here, it looks like there is a workaround that is non ideal but possible. Appears to not work at first try but will experiment.

Thoughts?

Exception handling for weather fetching failures

When the weather service fails, the code throws an exception and dies.

As there is no watchdog to relaunch the process (should I write one?), a better handling of the possible exceptions (fetching ics file, fetching weather, drawing the screen) should have try/catch statements.

I am creating issues separately, should I just use the suggestion/improvements? Or just pull requests (complicated, since the api key, city name and ics url are on the main code file). Which leads me to the next issue...

Incorrect power unit in README file

Hi,

the mainpage states:
"Altough mainly intended for the Raspberry Pi Zero W, mainly since it only requires 1W per hour, it works on the Rapsberry Pi 2/3 as well.".

My grievance is with the "1W per hour". Watt is already a measurement of energy per time making the statement physically nonsensical. It should either read "1W" or something like "1VAs per hour".

Also, (just noticing while writing) Altough is writen Although I think,
Cheers,
Frederik

Use a separate config file for settings

This way, I won't push my key by mistake here :-)

Info about translations

Currently the modules are mainly in English, although I indicate DE in the settings.
For the weather it says "now" instead of "jetzt"
In the calendar only the English is displayed for "today_in_your_language", "tomorrow_in_your_language" and "at_in_your_language" and no 24 hour view.

E-Paper Calendar fork from mgfcf

mgfcf's E-Paper Calendar fork

Amongst the forkers of this software,, mgfcf (Max G.) has been working hard on the E-Paper software refactoring. Apart from some more design options, it's also modular so it's easier to modify.

I am very thankful to Max G. for taking the time on refactoring the E-Paper software. But since there is hardly any 'perfect' software, bugs and errors can still occur. The aim of this issue is to provide a way to interface with mgfcf (for bugs, errros, etc.).

As usual, nothing and nobody is perfect, but we can strive to get closer towards that. Please post your comments in a friendly way and remember to be nice. Thanks for your understanding.

Suggestion: font sizes belong to settings.py

I have the calendar in a corner, and my vision is not that sharp as it used to be. Plus, our font rendering is not optimal.

Because of that, I use bigger fonts... And this configuration belongs to the settings, no?

VERSION file with the version number

Since you have version numbers now, it could be that either a file named VERSION containing the current version, or at least github tags, where one could see which one is the current one (I keep my fork in line with yours and I have no clue which version is it hehehe)

Feel free to close this if you disagree, of course!

Settings file not configured

It does this:

Auto-expansion of middle section modules

Hi,

I just tried the software with the V2 7.5inch E-Ink display.

As you already mentioned, the text is sometimes not correctly rendered. But within first tests, the functionality is given!

My main concern is the customization: I would just like to use the display for calendar entries, I really don't need the top and bottom area for news or weather. So currently these areas are empty for me (see image). Additionally, only the entries till Jan 25th are shown, although I have more entries (see also image below)

Is there any possibility to use the calendar on the whole display (complete top to bottom)?
(or to use the agenda view on the complete display?)

Agenda View did not display anything, but I will test it again tomorrow.

Another thing that would be nice is to set a text size, because the calendar entries have very tiny letters.

Other than that, I am looking forward to using it. I hope that some changes/settings can be done for future releases :)

Calendar events rectangles are in wrong places

Calendar in /dev branch has an issue - it shows (some) Wednesdays marked as event, but some actual events are not marked. /master branch is OK with the same calendar URL.

Weather icon missing on some weather conditions

I thought it should show something at the upper-left corner. In other weather conditions there's always something there.

iCalendar support for iOS Devices

Hi
I would like to know, if iCalendar is also synced from Devices like an iPhone?
Would be awesome to know (:

Crash on first use

I'm new to GitHub and Inky-Calendar, so apologizing if this is not the way to inform about issues.

I have 1 or 2 issues when using the program the first time, the first issue might perhaps be because of or related to the second.

1. Nothing is shown on the 3-color e-ink display.
   It's connected to a Rpi zero WH through the e-Paper HAT. When running the Inky-Calendar calibration.py from the terminal, the e-ink display is first blinking black, then white (shouldn't it blink red? EDIT: It actually seems to be very light red) and then finally white. This process is run twice and takes almost 10 minutes which I've understood is to be expected. The label on the back of the display has the text SKU13380 which is the 3-color display.

2. When running the E-Paper.py from a terminal, the weather is shown in the terminal window, but then a crash occurs (see below). Nothing is happening on the e-ink display, it's completely blank.

General Discussion, Support and Improvement ideas for releases < v1.5

Here you have an option to chat about improvement ideas regarding the E-Paper Calendar.

As usual, nothing and nobody is perfect, but we can strive to get closer towards that. Please post your comments in a friendly way and remember to be nice. Thanks for your understanding.

All improvement ideas are welcome.

Wavefront 9.7inch E-Paper support

Is it possible to use a Wavefront 9.7inch e-Paper HAT as well?

Python shebang defaults to python2

On Raspbian, #!/usr/bin/python defaults to python2, which can be an issue for this code. I would suggest to have it as "#!/usr/bin/env python3" instead.

Images not generated after the initial (first) execution

I really don't know, what I'm doing wrong, the first time when I run the inkycal.py script, the images for the calendar are created. After that all successive updates skip this step and no new image is generated. This is why at every update, the modules images are taken from the the first run. (The behavior can also be seen in the attache image, as no "Generating image" is observable in the first update after the initial start)

This is my settings.py (for testing I use the standard settings from the HTML settings creator):

ical_urls = ['https://calendar.google.com/calendar/ical/en.usa%23holiday%40group.v.calendar.google.com/public/basic.ics']
rss_feeds = ['http://feeds.bbci.co.uk/news/world/rss.xml#']
update_interval = "60"
api_key = ""
location = "Stuttgart, DE"
week_starts_on = "Monday"
calibration_hours = [0,12,18]
model = "epd_7_in_5_v2_colour"
language = "en"
units = "metric"
hours = "24"
top_section = "inkycal_weather"
middle_section = "inkycal_calendar"
bottom_section = "inkycal_rss"

Software crashes when setting weekstart to Sunday

When week_starts_on = "Sunday" and it is sunday the program crashes.

Issue can be repeated on every sunday.

Outdated Calendar Events

Submitting Issues

Finally got a working Waveshare e-ink 3-color display and got Inky Calendar up and running. However, while it is displaying the correct date the list of events on the bottom are very old (some weeks, some years). Also the sunrise/sunset times are very strange and, I assume, connected to a different timezone. Any thoughts?

Bug reports for release v1.7

BETA testing

Welcome to the BETA-testing of release v1.7. Thank you for willing to test the new software.
As the Installer of the new release is still work in progress, an alternate way to install the software had to be found. For now, the Inky-Calendar software is offered as a pre-configures OS image, which you can simply flash on a blank MicroSD card.

Below is the link on where you can download the image file. Below are the steps on how to set up the OS and the Inky-Calendar software:

1. Download and unzip the OS file (with 7z) from here: BETA-RELEASE

2. Format an empty MicroSD card (with SD Card Formatter) with at least 8GB space and flash the OS on the card (with Balena Etcher)

3. Open Editor (on Windows) and paste the following to setup WiFi:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=US

network={
 ssid="WiFi-Name"
 psk="WiFi-Password"
}

Edit the 2-letter country-code, ssid and psk with your own. Make sure you don't add spaces after the = signs.
Save the file as wpa_supplicant.conf in the boot directory.
If you have access to an Ethernet connection, you don't need to setup WiFi.

4. Add the SD card in the RPi and connect via VNC Viewer (preferred) or SSH.
   The hostname is inkycal.local ,the username is pi and the password is raspberry (default values). You can also use the IP address of the Rpi instead of the hostname.

5. Expand the filesystem in the Terminal with sudo raspi-config --expand-rootfs and set the correct timezone with sudo dpkg-reconfigure tzdata

6. VNC Viewer: Go to Inky-Calendar, open the settings folder and paste your details in settings.py
   SSH: cd /home/pi/Inky-Calendar/settings && nano settings.py

7. VNC Viewer: Open the modules folder inside the Inky-Calendar folder, open inkycal.py and run with the main programm file by pressing the [F5] key.
   SSH: cd /home/pi/Inky-Calendar/modules && python3 inkycal.py

Once the main programm has started, you'll see the E-Paper display being refreshed.

Updating

---

For those who have installed this software already and wish to perform an update, below are the instructions:

• Rename the current Inky-Calendar folder to anything you like, e.g. Inky-Calendar-old

• open the Terminal and run the following command:
  git clone -b dev https://github.com/aceisace/Inky-Calendar
  This will take some time as it will download 120 megabytes of data.

• Copy your previous settings file (in this case inside 'Inky-Calendar-old/settings/settings.py') and paste it in the settings folder of the 'new' Inky-Calendar folder. You can use this command as well:
  cp Inky-Calendar-old/settings/settings.py /Inky-Calendar/settings/. Replace 'Inky-Calendar-old' with the name of the old Inky-Calendar folder.

• Create symlinks (symbolic links) for the settings file and configuration file:
  ln -s /home/pi/Inky-Calendar/settings/settings.py /home/pi/Inky-Calendar/modules/
ln -s /home/pi/Inky-Calendar/settings/configuration.py /home/pi/Inky-Calendar/modules/

• Run the new software
  VNC Viewer: Open the modules folder inside the Inky-Calendar folder, open inkycal.py and run with the main programm file by pressing the [F5] key.
  SSH: cd /home/pi/Inky-Calendar/modules && python3 inkycal.py
