[Xorfor]

Since 12-oct-2017 retrieving values from Winddelen gives errors:

URL is changed. to https://backend.windcentrale.nl/windcentrale/productie?id=111 Line 90 from winddelen.cpp has to change from sprintf(szURL,"http://backend.windcentrale.nl/windcentrale/productie_%d.txt", m_usMillID); to sprintf(szURL,"http://backend.windcentrale.nl/windcentrale/productie?id=%d", m_usMillID);

mmm

Is this the solution for Domoticz to? When is this in the last Beta to find?? [ can some one make this fix please to domoticz beta? ]

Or where can i replace the changed line??

[Eternity-again]

I browsed my Syno directories hoping to find winddelen.cpp but couldn't find it...

[trandbert37]

I try to do this fix but it doesn't work for me

[Dylantje]

Is there perhaps someone that know who build the winddelen hardware..

Perhaps he can update the hardware..

[gizmocuz]

The problem is that the old URL gives a 403 (Forbidden) and the new URL never returns as it keeps pushing new data

[Dylantje]

My app is functioning ok... Perhaps there is a other feed..

I will try contact with windcentrale for a live feed...

[gizmocuz]

Your app probably has been updated... We need a URL that returns immediately, and not keeps the line open... maybe a GET parameter (or POST header) would be great (if it is not already there)

[gizmocuz]

Solved.. will work again in the next beta version

[Xorfor]

Just updated to 3.8614 and it works fine now. Thnx!!!

[Dylantje]

oke great work!!! Thanks! Gizmocuz

[Dylantje]

mm It still works :-) Perhaps for the masters 👍 I get a answer: `Dit is de betere manier:

https://backend.windcentrale.nl/-gxvt=1

of mag ook zijn: http://backend.windcentrale.nl/-gxvt=1

Dit gebruikt de app om productie van molenid 1 op te halen.

Als je die opent krijg je elke vijf seconde een regel in beeld (in Firefox en Chrome werkt dat in elk geval), dat ziet er dan zo uit:

Hij hangt na 5 minuten de lijn vanzelf op, om te voorkomen dat er runaway clients zijn (sommige Android telefoons openden om vage redenen meerdere verbindingen die nooit stoppen).

Die code gxvt in de url is een timestamp waaraan het serverproces kan zien wanneer deze link verstrekt is, en op basis waarvan hij kan oordelen of een link recent uitgegeven is.

Klein beetje technische achtergrond nog: dit is een server die één response geeft, waarin regel voor regel data doorkomt. Een basic http client voldoet dan meestal niet, omdat die vaak pas resultaat geeft als het laden van de pagina voltooid is - wat hier dus 5 minuten zou duren.`

Perhaps this can help when there is something wrong in the future :-)

Was able to install a beta Domoticz v6.1_3.0.8614-7 on my Synology and can confirm it is working again. Thanks!

[gizmocuz]

Hi Dylantje,

Yes that is the issue we have, we are a basic http client , so this does not work, we need an URL that returns immediately with 1 result line (and close the connection)

So the way i made it, it i will close the connection after i receive one line... so now we have a more advanced client ;)

[Eternity-again]

The problem seems to be back
