MMM-Webuntis

[kurkarte]

Hello,
I am experiencing an issue with your MMM-WebUntis module. Despite following the setup instructions and providing the correct credentials, I am unable to log in. After testing, I believe the issue may be related to the presence of an umlaut (e.g., ö) and/or a whitespace in the school name.

My Setup:
MagicMirror Version: v2.29.0
MMM-WebUntis Module Version: Latest from repository
School Name: Contains an umlaut (ö) and a space
Login Method: My school uses iserv (iserv.de) for authentication. I do not have direct login credentials for the WebUntis portal but instead rely on the QR code provided by the school, which works in the official WebUntis app.

Configuration:

Here is an example of my configuration (with pseudodata replacing sensitive values):

{
  module: "MMM-Webuntis",
  position: "top_right",
  header: "WebUntis Schedule",
  config: {
    students: [
      {
        title: "Student1",
        qrcode: "untis://setschool?url=kadmos.webuntis.com&school=schulname with ö and space&user=username&key=ABC12345&schoolNumber=1234567",
        useClassTimetable: true
      }
    ],
    days: 10,
    mode: "verbose"
  }
}

Error Messages:

Here are the errors I encountered:

When using the QR code:

[LOG]   ERROR for Student1: Error: Request failed with status code 400

Debugging with the check.js script

Error: getaddrinfo ENOTFOUND undefined

When manually entering the school name, username, and password instead of using qrcode:

Error: Failed to login. {"jsonrpc":"2.0","id":"Awesome","error":{"message":"bad credentials","code":-8504}}

Observations:

The QR code provided by webuntis contains the following (copied directly from the QR code content):
You see, the miscoding of the ö.

untis://setschool?url=example.webuntis.com&school=school name with � and space&user=username&key=ABC12345&schoolNumber=1234567

Notably:
The umlaut (ö) in the school name seems to cause issues.
There is also a whitespace in the school name.

Even when encoding the URL (e.g., using %C3%B6 for ö and %20 for the whitespace), I still encounter errors. I tried various configurations, including:

"school%20name%20with%20%C3%B6%20and%20space"
"schoolname with ö and space"
"schoolname+with+oe+and+space"
 ...

The QR code works perfectly in the WebUntis app, so I believe the credentials and format are correct. But my school uses iserv for authentication, meaning I do not have a standard WebUntis username and password.

@kurkarte you can try to search your school at https://webuntis.com/ . On the next site the school name in the URL could work if you replace empty spa es with „+“ signs.

@OliWer i pushed a fix to github.

I was able to reproduce your error.
it should work now.

[OliWer]

Data is getting displayed now, will play around with it more later. Thank you very much!

Hi, I am running on an RPI normally. The test system is running on Windows, yes. But both show the same issue.
I install modules the standard way, fro a git console by pulling and npm install.

I also tried without remote control module - same issue.

@HeikoGr Smashing, Heiko! Works perfect now! Many thanks!

@Eli said in MMM-Webuntis:

@HeikoGr Smashing, Heiko! Works perfect now! Many thanks!

Small update: Seems to work only when debug mode is true…

[HeikoGr]

@Eli maybe your school doesn‘t show more than 2 days to the future (like our school).

Because the only differences in the debug mode are more log output and not filtering past lessons (there is also an undocumented option „debugLastDays“ - so i was able to develop during the holidays…). How many future days do you see in the untis app or on webuntis.com?

[HeikoGr]

@HeikoGr a new commit is on github with a fix in the handling of “days” - maybe this fixes your problem.

[OliWer]

Fix works for me, thanks for your work!

[Eli]

@HeikoGr Sorry, for the delayed reply. You are acorrect, also works without debug mode. Seems there was some other hickup with the server and just next time I enabled debug again is was working again. So all fine.

Achtung, ich habe eine neue Version veröffentlicht und dabei die Konfigurations Variablen umbenannt - es muss die config.js angepasst werden.

Dafür habe ich jetzt aber auch eine Tabellenansicht implementiert:

@HeikoGr
Hallo & Vielen Dank für dieses tolle Modul!
I do love the module and especially the grid-view.

Is there a way to limit the number of hours displayed?
By that the vertical height of the grid-view could be reduced, I suppose.

I am asking because the generated table is exceeding the needed length to display the last hours of actual school, especially when there are weekdays in the grid which span across the whole day, like “kein Unterricht”.

I see there is a grid-comlumn-end, but I struggle to use it properly.
Thanks a lot in advance for any hint :-)

[HeikoGr]

@thk thank you for you kind word. I was able to implement a new config option “maxGridLessons” which will cut-off everything below the configured lesson. A “… more” badge is placed if an actual lesson is hidden because of this cutoff.

@HeikoGr
Perfect!
Thank you so much for this fast feature implementation, exactly what I was looking for.

Attention / Important

(for our school) Untis GmbH changed url and schoolname.
You may need to log in your (childrens) account(s) an edit the config.js according to the new values.

At least they didn’t switch off te old json-rpc api MMM-Webuntis is using

@schmucke, @HeikoGr
I have the same situation and i finally managed to receive the timetable for my daughter by using parents account. She did not register herself for Webuntis so no chance. I made a research on the module and the webuntis API.

By concept the function

getOwnClassTimetableForRange(rangeStart, rangeEnd);

must fail, because the parents account does not have an own timetable. So I used the function

getTimetableForRange(rangeStart, rangeEnd, id, WebUntisElementType.STUDENT);

The trick was to determine which “id” is to use. The id is meant as student’s id, in my case of my daughter. So I had to make a detour via

const studentList = await untis.getStudents();

I made a debug output of studentList to console and searched for the name of my daughter and found the id I needed for the function above. This list is very long because it showed all students of school (more than one thousand).
Afterwards I could use the function and received her timetable successfully.
It only worked by login with username & pass not by qrcode and only by hardcoded id because I did not find a filter method for the studentList, e.g. by name, etc. If available it should be possible not hardcoded but by config - Param.

[HeikoGr]

that’s great - i will look how i may use this in my module.
Thank you

Ein guten Morgen,

ich benutze Ihr WebUntis nun schon seid geraumer Zeit.

Leider musste ich feststellen das seid ca. 2Wochen keine Verbindung mehr zu WebUntis stattfindet.
mir wird jedes mal Error code 404 angezeigt.
Was ich mir leider nicht vorstellen kann, da ich es auch über Handy nutze und dort alle Termine sowie den Stundenplan einsehen kann.

Es wäre nett wenn ich dafür etwas Hilfe bekommen könnte damit dies wieder angezeigt wird.

MfG
Krause

@Rondejavu gerne:

Ich vermute, dass die Antwort schon hier im Forum ca. 3 Beiträge obendrüber steht. Untis hat an den Servern gearbeitet - evtl. müssen hier die Verbindungsparamter neu eingestellt werden.
