Hello, Is it possible to retrieve messages "as in Vicare" informing us of updates on Viessmann servers from the API? Thanks for your help.

WSchafmann · ‎26.02.2024

Please ignore my question above - I got it 😉

nerixs · ‎28.11.2023

Ich habe das gleiche Problem! Die Stabilisierung der Viessmann Server ist immer noch sehr gut!

Hi @MichaelHanna , Back to the news. The easiest way for maintenance information would be to provide access to: "heating.service.timeBased: activeMonthSinceLastService, serviceIntervalMonths, lastService, serviceDue". Have you been able to discuss this with your team? Cordially

hello @Boeb, the first step (Authorization Request) always works (almost) exactly as shown in the documentation. For demonstration puposes, Viessmann used a browser to make the call with the bogus listening/webhook address of http://localhost:4200. This of course results in a browser error message but the authorization code is created nonetheless as part of the URL shown in the browsers address line. To automate this, you need a calling app that is also providing your credentials automatically. Viessmannn responds to the request by sending stuff to the Redirect URI. Your app has to listen to the redirect URI. The URI can be anything but has to be set and saved in the edit client window of the developer portal. I'm using Node-Red running on a Raspberry Pi. Node-Red is using portnumber 1880 for html responses, hence the Redirect URI is set to http://localhost:1880 Frankly, I'm not sure why you want to use .NET for this - unless you have a low power consuming hardware on which it runs. Using the API in a 24/7 fashion definitely isn't something for a desktop computer. It's much easier to have the Interface to Viessmann running on a Raspberry Pi or similar and access it with a browser. Or do you intend to duplicate Viessmann's ViCare App on a mobile device? Also this article could be helpful in understanding the Authorization Request. Also some of my other articles and tutorials in this forum might provide more info. Hope this helps. Kind regards Chris

Hi @MichaelHanna, Thank you for this procedure. Better, Eric

Hallo an alle im Verlauf, ebenso @MichaelHanna Dieses Thema erneut aufgreifend ..... heating.buffer...... features sind zwar jetzt beschrieben, was bitte ist aber der Unterschied zwischen load und temperature? Ich habe eine Anlage (Vitolignio 300C, Solar und multivalentem Puffer) und 4 Temperatur Sensoren. Eine Abfrage der Buffer Features bringt: heating.buffer.sensors.temperature.top, $resp "{"viErrorId":"req-21b1aab121004cafb78ffab22d059cde","statusCode":404,"errorType":"FEATURE_NOT_FOUND","message":"FEATURE_NOT_FOUND","extendedPayload":{}}" Wo bitte liegt mein Fehler? Liebe Grüße HackyJ

Hallo, Mein Gaskessel Vitodens 222-W B2LB 19 kW Bodenheizung, 11% Modul bei 0° Aussentemperatur. Bei Wind ist die Modulation mit viel kürzeren Zyklen schnell auf 35 % gestiegen. Welche Art von Rauchrohr kann ich benutzen, um den Gegenwind zu reduzieren? Ehrlich

The reason for ( a lot of ) more datapoints being returned started on Dec 2nd for me. Actually the used Regex statement was not used and ALL datapoints were returned. This misbehaviour was corrected today. However the order of the returned datapoints is NOT fixed, for that reason the USORT function will not help!

@JueBag, Thanks for your help. It helps a lot. Best regards

Hello @MichaelHanna, Can you give us an answer regarding the maintenance data? Does the eventType: device_message_service work in this direction? Best regards

MichaelHanna · ‎20.08.2021

Hi @nerixs , we added new features to the list of features. You can find them in the feature overview list: https://developer.viessmann.com/en/doc/iot/data-points and the changelog: https://developer.viessmann.com/en/doc/changelog Best, Michael

MichaelHanna · ‎12.08.2021

Hi @nerixs , Thanks for the feedback. We will have a look at the consumption features.

MichaelHanna · ‎06.08.2021

Hello @nerixs , I replied to this issue in the thread you mentioned. For completeness, let me also add it here. We have checked with our development team and did testing on the mentioned issue, but could not find any bugs on the logic. After reaching limits, requests are not counted at all so they can’t lead to extending ban. If the issue still occurs on your side, please contact me directly via PM and provide us with steps for reproducing the issue, as well as your user id (login name) and your client id (API key) to remove the >24h ban. Best, Michael

MichaelHanna · ‎02.08.2021

Hallo @ceeage , um deine Daten via API abzurufen, musst du dich zunächst authentifizieren. Die Authentifizierung nutzt den sog. "OAuth" workflow. Hierbei ist die redirect_uri die Adresse, die bei der erfolgten Authentifizierung aufgerufen wird. Du kannst die redirect_uri frei wählen, sie muss aber in den Einstellungen deines API Keys und in deinem Befehl identisch sein. Für Testzwecke bietet es sich an, als redirect_uri "http://localhost:4200/" (ohne Anführungszeichen) zu verwenden. Bei der Nutzung der API über eine andere Applikation wird meist verlangt, eine bestimmte redirect_uri zu verwenden. Hast du schon in die Dokumentation auf dem Developer Portal reingeschaut? Dort haben wir eine Anleitung für die Authentifizierung: https://developer.viessmann.com/de/doc/authentication Ansonsten kann ich dir auch empfehlen, den Sample Code aus @nerixs Beitrag zu testen (Thanks nerixs!) Den ReCaptcha kannst du in den Einstellungen zum API Key aus- und einschalten (während des Erstellens oder beim nachträglichen editieren). Aus Sicherheitsgründen empfehlen wir, ReCaptcha einzuschalten, für die Automatisierung ist das Captcha allerdings abzuschalten. Gruß, Michael
