MagicMirror² v2.14.0 is available! For more information about this release, check out this topic.


  • Description
    Since the existing module to display Pollen information from Germany seems to be broken, I wrote a new module but used the US version as a template (MMM-Pollen).

    The data is sourced from DWD.

    Hi Carsten,
    love the idea of this module. I have just installed it with DWD_region: 120, for Bayern. It does not show any data. Does that mean there is no “Pollenwarnung” for today? When I put in the default DWD_region: 92, it shows me two values for Erle. If this is not a mistake, it might be a goog idea to show something like “Keine” when there is no “Pollenwarnung”.

    Thanks and excuse my bad English 😉

  • @thedoorsfanatic

    thanks for the hint. I am parsing for the partregion_id which in case of of Bayern has 4 sub regions 121-124:
    121 Allgäu/Oberbayern
    122 Donauniederungen
    123 Bayern n. der Donau, o. Bayr. Wald, o. Mainfranken
    124 Mainfranken

    There is a map showing the regions (even though the numbers are wrong):

    But good idea with the “no data” warning.

    Thanks (btw, I mad a bug fix yesterday that prevented some of the items showing up)

  • Hey @CarstenD,

    thanks for the update. I put in DWD_region: 121, for Munich and now it shows up data.
    Keep up the good work!

  • New version available with icons as alternative display

    Hi Carsten,
    I have installed the module MMM-DWD-Pollen according to specification. Unfortunately it (as the only module) does not provide any data. I have also tested different DWD regions (81,92 and 122), but it only shows “Load …”. tcpdump (tcpdump -n host -A -s 0) shows no connection attempt to

    npm run config:check

    magicmirror@2.11.0 config:check /home/pi/MagicMirror
    node tests/configs/check_config.js

    Checking file… /home/pi/MagicMirror/config/config.js
    Your configuration file doesn’t contain syntax errors 🙂

    What can I do to isolate the error?

    @Sachse - Have you tried running the mirror in developer mode and looking for errors?

    x:~/MagicMirror $ npm start dev

  • @bhepler said in MMM-DWD-Pollen:

    npm start dev


    you mean the error messages in the bash or the console of Chromium?

  • Hi Mate, could you do the same for Switzerland? Or chat bilateral to talk about what is required and I will see what I can organize. Thanks!
