@Marioo sounds to me like you will have to change the battery, again 😞   @Fiedel thanks for pointing out to a working battery tester 🙂  Would you be so kind to recommend a battery too? ... Mehr anzeigen

Hallo  @MacVito ,   danke für deinen Vorschlag. Ich habe die ViCare-Statistiken der letzten 4 Jahre, daher sollte es kein Problem sein, sie mit den Messwerten des Anbieters abzugleichen und ein Verhältnis festzulegen. Natürlich ist es der Anbieter, der den „richtigen“ Wert angibt. Was deine Frage betrifft, die Zustandszahl ist der Wert, den ich am Ende des Jahres gemeldet habe, oder? Allerdings habe ich keine Ahnung, wo und wofür ich den Brennwert angeben soll. Ist es Teil der Vitodens-Konfiguration? dort habe ich noch nicht nachgeschaut. ... Mehr anzeigen

thanks @Marioo for the photo and infos, I'll check at the next chance.    Anyway, now it seems obvious to me I must have a battery too (s. Bedienungsanleitung für den Anlagenbetreiber):  "Uhrzeit und Datum sind werkseitig eingestellt. Falls Ihre Heizungsanlage längere Zeit außer Betrieb war, müssen Sie ggf. Uhrzeit und Datum neu einstellen."   As of the ViCare app, this feature has been there for a long while. It's just the standard API that misses it. ... Mehr anzeigen

@Marioo  schrieb:   ... I have no slightest idea why the gateway doesn't sync the clock automatically! For me, this is one of the primary features this device should handle. @Marioo a real nightmare! what is your heater's model? I wonder if the VITODENS 300 (my case) has a battery that needs to be replaced too, and nobody tells the user 😠       This feature is not a big deal to program an should be part of an to come software update! Maybe one oft the Viessmann guys like @CustomerCareChris can handover this idea to the developers. @Fiedel  ,@Customer_Care , 4 months later, are there any news from your developers?   Thanks!   ...

Good night @Fiedel ,   the problem is back. ViCare App and API stopped updating at 02:00 last night. Heater panel shows (like in all my previous reports) an active connection to the server. Resetting the connection did not solve the problem. As a test I used the API to change the water temperature. The ViCare App immediately updated showing the new target temperature. The Vitodens panel however did not show it, even after 5 minutes.   Any ideas what can be causing this?  It is really frustating that ViCare and the API live in their own "cloud" and don't bother to synchronize with the heating unit. 😠 ...

Good morning!    last night the Vissmann server (and ViCare app / API) all of the sudden and without any actions from my side stopped being "frozen" and started showing up-to-date information 😅  this after 72 hours of incorrect information! 😠   @Fiedel , @CustomerCareBen , @CustomerCareChris  any ideas why the server was out of sync with the heating device and still didn't report a communication error? what caused it to restart "talking" to the heater? I wonder how Viessmann is offering priced ViCare services when the basic realibility is not given 😕   Thanks! ... Mehr anzeigen

Hi all,   we have again the same problem. It started yesterday 20.08 around 02:00. SInce then, the ViCare App and the Viessmann API are out of sync with the VITODENS 300 and show the same unchanged status all the time. I tried a power off/on cycle as did last time, but this time without success. The VITODENS 300 touch panel shows correct, up to date information (outside temperature, date/time, online status, ...) the app doesn't. Any ideas of what could be causing this?  to me it seems more like a problem in the Viessmann server!   Thanks in advance for your help 🙂 ... Mehr anzeigen

Thanks @Fiedel, I take you at your word 👍  Let's see how long it takes to receive a response and update from development. If you need someone to do beta testing here I am. Thank you! ... Mehr anzeigen

Thanks @Fiedel , in this case it seems the clock of my VITODENS 300 can only be set MANUALLY.  For me, it means all heater schedules (boiler and pumps for warm water and heating) and optimizations made using ViCare or similar smarthome tool using the Viessman API will stop working as intended in case the VITODENS 300 clock is reset. This may happen inadvertently after a power lost.   It also means there is no way to detect it, except when the end user notices it (i.e. water to cold) or visually checks the heater's datetime in the touch panel.   This is a pity or even a shame 😩   ...

No NTP through the operating panel, but perhaps through the Vicare API?     Verifying and/or setting the date/time through the API would prevent similar issues in case the local clock goes bananas ... ... Mehr anzeigen

Hi @Fiedel!  thanks for your prompt reply. Here the serial info's: "HeatingBoilerSerial": "7560881502880101", "HeatingControllerSerial": "7555113508520100" Would be great if you have a way to automatically correct date/time should it go wrong. All the best ... Mehr anzeigen

Good morning @MichaelHanna,   the infos in the documentation allowed me to move a bit forward, but now I'm stacked with the "authorization code". As already mentioned I tried with the browser (as indicated in the documentation) and with Postman (following an earlier recommendation) with no success.    How do I get the "authorization code" so that it can be used with Postman?   Thanks! ...

Ok thanks @MichaelHanna.  I have now entered my client_ID, redirect_uri (vicare://oauth-callback/everest) and created a code_challenge.   After clicking send I get status 200 OK and can see the HTML output, but cannot find the "code" which I believe to need for the next step (POST Authorization code exchange). I also tried copying the resulting URL into my browser (Edge Win10) as suggested in the documentation. This took me to the login screen. I entered my userid and password which seem to be accepted but got no "code" I could use in the "POST Authorization code exchange" step.    What did I do wrong?  how do I get the "code"? ...

Hi @MichaelHanna !   thanks for your patience. With your help I have now created myWorkspace importing the collection you provided. Then I went to Authentication / GET Authorization Request and set client_id to the 32-characters string from "your clients" in my Viessmann's developer account. I clicked then the Postman GUI SEND button and got:    "error": "Invalid redirection URI." What should I enter as "redirect_uri" ?  and  what as "code_challenge"? My goal is to test the API data points that are giving me problems under pyVicare. Thanks! ... Mehr anzeigen

Hi @MichaelHanna ,   thanks for your support. In the meantime I:   created a text file containing the "collection" you supplied registered a Postman userid login to my userid (via browser) and tried to "import" this collection, but cannot find an "Import" button Am I on the right track?  in which Menu/Submenu I need to get to find the import option? Sorry for the very dumb questions, I've no Postman knowledge whatsoever.   Thanks.   ... Mehr anzeigen

Hi @MichaelHanna ,   thanks for your reply. I can now see the changelog. Concerning the heating.circuits, it resumed working short after your reply, without any changes from my side 🤔  Now all of the sudden, heating.burners stopped working. Last successfull call was on 2022-06-14 12:27:17 however the changelog does not show any changes in June. 🙄 Now I'm wondering if these errors may also occur as a result of an operational problem in your server and/or in my burner. What do you think?    I have been pointing to development changes but perhaps it is not their fault. Is there a way to check this?   Thanks!   ... Mehr anzeigen

Hi everyody, @MichaelHanna    unfortunately I must go back to this old thread to report a new (old) missing point error, this time is <heating.circuits>. It suddenly stopped working a few days ago. I'm using the pyvicare python library. I tried to look at Viessmann's changelog but got a broken link (https://developer.viessmann.com/de/doc/changelog) Any ideas or information what has changed? Thanks ... Mehr anzeigen

Hallo @MichaelHanna,   Dieser Datenpunkt fehlt mir auch! es war Mitte 2021 schon einmal verschwunden und wurde dann im Oktober restauriert <Missing data point heating.burners.0.statistics ... - Viessmann Community (viessmann-community.com)> Was ist los? Ich habe gelesen, dass es jetzt endgültig weg ist. Ist das Wahr? Wer trifft solche Entscheidungen, ohne sich um ihre Auswirkungen auf die Benutzer und die Community zu kümmern? Gibt es einen neuen Anruf/Datenpunkt, um dieselbe Funktionalität zu bekommen? Ich nehme an, Du bist genauso verwirrt wie die meisten API-Benutzer 😞 p.s. Ich bin auch seit Jahren Benutzer der Honeywell/Evohome-Schnittstelle. Es ist auch aufgrund der unterschiedlichen Typen/Modelle von Geräten, die es unterstützt, breit und komplex, aber ich musste nie eine Codezeile ändern, weil es zu Breaking Changes in der API kam. Ihre Entwickler kümmern sich um die bestehende Benutzerbasis und implementieren Änderungen/Erweiterungen in einer nicht störenden Weise. Es ist möglich! ... Mehr anzeigen

Hi @MichaelHanna ,   thanks for your reply. I hope your development is able to localize and provide a fix for the "heating.circuits.N.circulation.pump" problem. Unfortunately I need to report another problem introduced with the October update that I just noticed:  the daily gas consumption value for domestic hot water (heating.gas.consumption.dhw) is not being updated. It always returns the values (7, 15, 18, 17, 15, 21, 22, 18).    Is this a known Problem? Thanks   ... Mehr anzeigen

Hi @MichaelHanna    I don't know if you ever got a reply from your development, but the feature ( (burner-hours and burner-starts) is now working for me 🙂  unfortunately at the same time heating.circuits.0.circulation.pump stopped working. Is this a known problem? At this stage I'm wondering if all this API is really intended as a serious, professional platform, or is it just somebody's playground.  ... Mehr anzeigen

@MichaelHanna  yes, it is still available. I'm not familiar with the gateway models, but it is indeed a wired connection. Why should this matter for the software API?  it takes almost 2 months for your development to react and then this reply?  Hmm not the Viessmann I was used to ... ... Mehr anzeigen
