Loxberry Vitoconnect

[wiggo87]

Is there already a solution?

[mantal]

What is needed to be done so my LoxBerry will work again?

[Marco74]

This was a quick and dirty change to make things work again for me using v2 calls. This is definitely not a final solution.

The original code only used the v2 for the Viessmann_SetData, not for the Viessmann_GetData calls. And it seems the GetData v1 calls are now also depreciated.

And the original code has:

define ("apiURL", "https://api.viessmann-climatesolutions.com/iot/v1/equipment/");
define ("apiURLv2", "https://api.viessmann-climatesolutions.com/iot/v2/features/"); 

Those are 2 different endpoints for different things and not just a V1 and a V2 endpoint. I think the v1/v2 switch has to be implemented a bit differently.

I dont't get your change. In defines.php you have apiURL and apiURLv2. You can select which you want to use in the web UI below the credentials.
You canged the apiURL and in vitoconnect.php you canged apiURL to apiURLv2. So your change in defines is not used!?

[Marco74]

I had the same issues yesterday where I got the installation info, but not any details. There was an error in the log about a deprecated call.

I edited 2 files and that solved the issue (of course until the current outage):
defines.php

define ("apiURL", https://api.viessmann-climatesolutions.com/iot/v1/equipment/"); 

Changed to:

define ("apiURL", https://api.viessmann-climatesolutions.com/iot/v2/equipment/"); 

vitoconnect.php

$installationDetailJson = Viessmann_GetData (apiURL."installations/".$Install->general->id."/gateways/".$Install->general->serial."/devices/0/features/" ); 

Changed to:

$installationDetailJson = Viessmann_GetData (apiURLv2."installations/".$Install->general->id."/gateways/".$Install->general->serial."/devices/0/features/" ); 

Not a thorough solution, but I managed to control my heatpump again.

Ich denke wir müssen kurz mal abwarten. Der API URL Change sollte im Plugin schon drin sein.
Auf der Viessmann Developer Seite steht aktuell folgender Hinweis:

Outage
Our systems are currently experiencing major outages.
Therefore, requests in the Developer Portal cannot be processed.

Daher wird sich wahrscheinlich alles wieder ohne Änderung ergeben...

I have got the same issue from yesterday, I see only info about installation-ID, Serial, version, modelID, country etc.. but not info about temperatures, power, gas consumption.. :/

Loxberry : 3.0.1.3
Viessmann Vitoconnect vs. 1.1.1

[Wing_Stefan]

Hallo, bei mir geht seit ein paar Tagen die ViCare app nicht, also ladet nichts. Habe VitoConnect heute resetet neu ins Netz gehängt, Auf Loxberry hat seit ein paar Tagen keine Daten bekommen.
Habe die Info bekommen das die developer URL ausläuft und sich ändert ab 26.11 glaube ich stand dort: Viessmann Developer Portal | Viessmann Developer
Weiters auch gesehen das es eine neue Version gibt. Hier waren aber Errors drinnen:

Schlimm?, Problem ist ich bekomme trotzdem keine Daten auch die Vicare app neu installiert und dort kann ich mich nicht anmelden, proxy error kommt als Fehler, ich habe keinen Proxy.

[mantal]

I am getting the same error. It seems that Viessmann Developer Portal and API services are experiencing some technical issues. I can not access Viessmann Developer Portal using web browser neither.

[seppal97]

hab ich schon beides versucht

[challo]

Vielleicht loxberry und vitoconnect Mal Neustart

[seppal97]

Hallo, kurze Frage von mir. Ich habe jetzt eine Zweite Anlage in Betrieb genommen. Leider kommen nun keine Abrufe mehr von der ersten Anlage. Bein Data wird auch nur die neue Anlage angezeigt. Ist es möglich, beide Anlagen mit der API anzusprechen?

besten Dank
Alex

[challo]

die Umschaltung ist schon länger drin! Gestern gab es wohl auch eine Störung der V2 API. Ich war auf v2 aber es hat gestern trotzdem nicht funktioniert. Jetzt geht es aber wieder!

[Simon_oO]

Danke der Tipp war Gold Wert! Das habe ich nicht mitbekommen. Jetzt läfut wieder alles :-)
