MMM-DWD-Pollen

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 ;)

Hi,

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): https://www.dwd.de/DE/leistungen/gefahrenindizespollen/Gebiete.html?nn=16102&lsbId=463856

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!

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

@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?

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!

CarstenD

@duxnobis In general yes, I think Switzerland gets data from Meteo Schweiz (https://opendata.swiss/de/dataset/messstationen-des-nationalen-pollenmessnetzes)

CarstenD

@TechJak7000 said in MMM-DWD-Pollen:

Astma-Allergi Denmark

I found some information here: https://github.com/rugaard/pollen
Thus it looks like Astma-Allergi Denmark does not offer any official API. Thus you have to use this API here (which I guess takes the data from the website) and renders the data accordingly. There are only two regions as far as I can see (East and West?) and 25 pollen. If the API works it should no big problem.

TechJak7000

@CarstenD Thank you very much for your attention and effort. I have contacted the owner of the post to have more in depth information how to go about and use this API.
As far as my limited knowledge for implementing this, one has to install / use 2 different programs systems to utilize it, and I have sent the guy a message with and example of the “MMM-pollen” to give him and idea of what I am looking for and how can I implement this, I hope I get a useful response.

CarstenD

Added the option to select which Pollen to display through config.

MajorC

I have the DWD-Pollen on the right side of my scree. Unfortunately, there is a gap as you can see in the picture.

I checked the CSS, but it is a table and I can’t see a good way to get rid of the space on the right.

Any idea is appreciated.
