Hi all,

I’m facing exactly the same problem on my RPi3. The screen is all black and shows only the mouse arrow. I can access the MMM-RemoteControl from a separate notebook or mobile and it is possible to remotely restart the MM software to bring everything back to normal.
With a connect mouse you can move the mouse pointer but still there is a black screen. below please find the result after typing pm2 log mm

in the log is written… Maybe no Internet connection? but this is definitely not true…

Anybody an idea why this happens?

Thanks also from my side… this is exact the module I was looking for. Is there a way to change the “STR” into “Tram”? Thanks for your help.

@raywo said in MMM-PublicTransportHafas – Public transport information for all stations known to Deutsche Bahn:

.str11:before {
content: "Tram ";
}

works perfectly…
thank you for the prompt support

Hi there,
while configuring this awsome module another question came up. is there an way to get rid of the city name being displayed behind the final destination of e.g. the bus? In my configuration I want to remove “München”.

Thanks in advance…

@raywo Thank’s… best support ever

One more css question popped up while I reconfigured the appearance of the module

There is a train called Meridian stopping at our station. If I do not add any css style for this train it appears as the 5 digit train-number only that changes depending on the time of day.

I want the module to show only the name “Meridian” for all of the trains. So is there a possibility to rename all train numbers to “Meridian” only without showing the train number?

Below please find the css code I’m currently using:

/* Meridian */
.m79600:before {
  content: "Meridian";
}
.m79500:before {
  content: "Meridian";
}
// ... and so on for every train number

thank you for yuour help…

Hi @raywo , Hi all

I’m using the MMM-PublicTransporthafas (https://github.com/raywo/MMM-PublicTransportHafas) module for more than 2 years now and I’m really happy that it exists. Since several month unfortunately this module is not working for 100% anymore and some of the bus or train stops can not be recognised anymore. After some internet research I found that the hafas-client used in this module was updated several times, see: https://github.com/public-transport/hafas-client
I’m not very familiar with java coding and do not know how I can adapt MMM-PublicTransportHafas to the latest version of hafas-client. Is there anybody who can help to solve this? it would be a shame to loose this nice and universal module just because a simple but necessary update cannot be done.
I really appreciate your help!
Thanks
onkelbobby

@chris1971
if you just wanna remove the wind in the forecast tile try to add that line in MMM_DarkSkyForecast.css

.MMM-DarkSkyForecast .wrapper.tiled .forecast-container .forecast-item .wind-container{
  display: none;
} 

of course it makes sense to remove the existing line before
hope this helps

Minimizing to font size should not be a big thing. If you open the module specific css file you an search for font and play with the values in that section. Note that you need to restart MM after saving the modified css file.

I implemented this fantastic Modus and it integrates almost seamlessly into our existing mirror layout. To make it perfect I need to reduce the gap between the time and the icon as wells between the day and the icon (yellow arrows). and also between the individual block’s (arrows in red)

I know that I have to modify the .css file can someone give me a hint what would be the correct values to be changed?
Thanks

@htilburgs
mine is connected to an Arduino micro 3.3V version and this one is controlling a simple relais switching the monitor inside the mirror. But as @MadScientist already mentioned you can also hook it up to the Raspberry Pi since It works perfectly with MMM-PIR-Sensor.

I did not use PIR sensor because it needs to “see” through the frame. After a little research I found an microwave based motion sensor called
RWCL-0516. This tiny PCB works super reliable even though ma 20mm thick wooden frame.

no ideas?

…finally the module is working like a charm since more than 4 weeks. I think this was an issue with the data provided.

I updated our mirror to 2.4.1 about 2 weeks ago… since the new software is running we don’t see black screen anymore…
