MMM-Departures - Public transport departures based on Oeffi data

[Ashidian]

Nice! I really love the oeffi app and always thought it’s a pity that it’s not available through an webpage.

I will definitly test this out and maybe make contributions. Could you provide some screenshots? That would be awesome.

I can only guess, but I don’t think the module will need changes. The providers data is fetched through the REST wrapper initially provided for a FHEM home automation module, and I thankfully may use it too. As I understand, behind the wrapper runs a instance of https://github.com/schildbach/public-transport-enabler which is actively maintained by Andreas Schildbach. And this enabler is the core unifier for the different providers.

@BenGig I know the repository from Andreas, if your module use this code, I suppose his changes will also work on your module. In between, I installed your module and it works perfect for my home town, what else could I need. It’s great.

[sindbad6]

After updating of MM to 2.1.1 and updating your module I get no data anymore. I get only the information “Lade” means load or wait. Any idea why this happens?

Both was installed with git hub && npm install
Anything I have to do?

[BenGig]

No idea yet. I just upgraded to 2.1.1 and have no issues.

Do you see any error messages in the browser console?

[sindbad6]

@BenGig No, there are no messages belonging your module.

[BenGig]

I added a global config option which will give some output to the browser console:

    {
      module: 'MMM-Departures',
      position: 'bottom_left',
      config: {
        debug: true,
      ...

Results should look like this:

Processing station Aazopf
- Departures found: 5
-- Processing departure: NFB21,Arth-Goldau, Bahnhof,333
-- Processing departure: NFB21,Arth-Goldau, Bahnhof,374

Well, should…

[sindbad6]

@BenGig I tried the debug mode. The only things I get is
Module helper loaded: MMM-Departure and
Connecting socket for: MMM-Departure
nothing else to see. Sorry! :disappointed_relieved:

[BenGig]

I have added more debugging output, and an error output on the system console if a call to the web service fails.

And: most debugging output appears in the browser console. Hit F12 to open the development panel (Firefox or Chrome), and switch to the tab “Console” if not initially active.

[sindbad6]

@BenGig Find out, that the error only occurs if I set

absoluteTime: false,

If the parameter is set to true or the parameter is commented out the module works fine. Before the updates this setting works fine.

[BenGig]

Great, that helped, problem found and fixed!

[sindbad6]

@BenGig Yeah, here the same, it works now. Thanks to you. Just for curiosity, what did you change? What was the problem I have no idea in javascript programming and would like to learn something about it.

[BenGig]

@sindbad6 I refactored part of the main routine into a subroutine. A variable which was defined in the moved part was also used in the main routine, in the part for absolute time calculation.

[sindbad6]

@BenGig Ok, I understand. At the moment I have two other issues.

The first is, that even, if I switch off the debug mode, I get dozen of messages in the terminal, where I start the mirror. I suppose the parameter is not handled properly.

The second is, that the time values for the relative time display flickers for maybe a tenth of a second to another value.

Can you evaluate this?

I’m looking through the git and I don’t see Washington DC listed as a possible sight, am I missing something?

[BenGig]

@lucallmon maybe a suitable provider can be found, here https://oeffi.schildbach.de/ I can see a general “USA (local and regional, e.g. Philadelphia, Chicago)”. Maybe Washington DC is supported? Since there are so many providers I don’t know in detail what is provided.

Here in Switzerland the main provider aggregates national and local information for train, bus and tramway, so there is no city specific provider.

[BenGig]

@sindbad6 Can you paste some of the output? I can see general output from all modules but no debug from mine (and I checked with absoluteTime: false too ;). And the part of the configuration with the debug turned off.

[sindbad6]

@BenGig You find the output below. It’s allways the same. :slight_smile:

MMM-Departures error: null
MMM-Departures error: null
MMM-Departures error: null
MMM-Departures error: null
MMM-Departures error: null
MMM-Departures error: null

[BenGig]

@sindbad6 That’s not debug output, that’s a problem in the code.

Can you post it as an issue in github and add your configuration, if possible? Looks as if your config triggers an error mine doesn’t.

[BenGig]

@sindbad6 Added the “flicker” issue to the tracker, have just noticed the effect.
