@CarstenD
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 141.38.3.62 -A -s 0) shows no connection attempt to https://opendata.dwd.de/climate_environment/health/alerts/s31fg.json

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

[Sachse]

@bhepler said in MMM-DWD-Pollen:

npm start dev

@bhepler

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

$ npm start dev

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!

[bhepler]

@Sachse - I mean the console in Chromium. The dev mode should display the console on your mirror so you can see the log from the display layer. The log in “bash” is the log from the back end (the node_helper.js and similar scripts).

@Sachse said in MMM-DWD-Pollen:

ERROR] Error: listen EADDRINUSE: address already in use 127.0.0.1:8080

This means that some other process is already using port 8080 on your Pi. Usually, this means that you have two instances of Magic Mirror running. You may have something else using that port, but usually it’s another script attempting to also run your mirror. First, let’s check if PM2 has two instances defined. If you type pm2 status all what do you see?

General principle: You can ignore just about everything in a log file unless it is preceded by ERROR.

[Sachse]

@bhelper

Ohh, this is almost embarrassing. I could have figured that out myself by looking at netstat -plan|grep 8080. I was just irritated that the other modules worked without problems, so I didn’t suspect the error there. The module “MMM-DWD-Pollen” works great now :-)

Thanks for your support

Hello Carsten,

Thank you for making a such a useful module, just out of curiosity would like to know that you can the data free from DWD, I would love to have one for Denmark, I tried to contact the AAD :- “Astma-Allergi Denmark” but could not find a solution.

I was wondering if you can assist me making one for Denmark, I will be wonderful and beneficial for many.

Best Regards
JG

[bhepler]

@Sachse - Glad you got it working!

Don’t worry about the “gee, I could have figured that out for myself” thing. Today, it took me hours to realize that one of my customer’s problems was he had the wrong time zone set on his laptop. It’s the simple fixes with vague errors that hurt the most.

[CarstenD]

@Sachse Glad you got it working with the support from @bhelper. Sorry that I could not reply fast enough. Thanks for using!
