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.

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

@HeikoGr
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!

@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!
