prima, habe jetzt einen neuen Beitrag eröffnet und für mich sieht das jetzt so aus als wenn ich wieder ignoriert werde. Hätte zumindest mal eine Reaktion des Typs " ist zur Kenntnis genommen und wir kümmern uns" erwartet.  Der Frust gräbt sich tiefer und tiefer ! Aber was schreibe ich hier denn noch Beiträge Viessmann juckt es ja doch nicht. ... Mehr anzeigen

Hallo, Puffer als Heizkreis,wie meinst das? ich habe auch Weiche und Puffer und nen B3HA,mit dem richtigen Schema funktioniert das wie verrückt, Hauptsache man durchströmt nicht den Vitodens mit der heißen Brühe ausm Puffer.    Gruß  ... Mehr anzeigen

@Nochdhesse  jap, funktioniert jetzt bei mir auch wieder. Irgendwas is definitiv anders, weil jetzt kommen ohne das / vor dem 'Bearbeitung zulassen' zumin schon mal die Knöpfe, die vorher garnicht mehr auftauchten... Bei mir ist die 'alte' auch etwa 50kB kleiner.   danke für die Aktion! 🙂 ... Mehr anzeigen

Hi,   I have as well the impression that API calls are not counted as should be: I am polling data every 30 minutes. For some testing, I added another job to poll every minute starting 1.00 (at night). At around 12.30 (noon), I exceeded the API limit - with 1 call/minute, it should have been working almost  the whole day (due to the additional 30 min calls). What I forgot - due to issues retrieving data, I added auto-retry into my coding   in case the API call failed and didn't retrieve data, it tried up to 5 times. My impression: 1) The retries due to failures got counted 2) The API fails quiet frequently   Why that? Thanks, Cbo   ... Mehr anzeigen

Hallo Zusammen,   gibt es zum Thema "Vorlaufsolltemperatur bei witterungsgeführtem Betrieb" bereits neue Erkenntnisse?   Eine wertvolle Information zur Bewertung der Heizungseinstellung fehlt mir in meiner Auswertung.   Vielen Dank Stefan ... Mehr anzeigen

Hi @davids1 ,   I would not expect a gateway restart is the intended flow for changing the heating circuit operating mode (I expect you are using the feature heating.circuits.N.operating.modes.*).   Could you share the complete API call you are using to change the operating mode?   If you change the operating mode through ViCare, do you also need to restart your gateway to see the correct readings?   We do not offer a feature to restart the gateway via the public API. You can find all available gateway related features in the IoT features section of the documentation: https://documentation.viessmann.com/static/iot/data-points   Looking forward to hearing back from you!   Michael ...

Temporarily I am using a workaround to achieve my "goal" using Node Red.   "Heizmodus abfragen" is now polling heating.circuits.1.operating.programs.active "Temperatur festlegen" switches to one of three outputs depending on the given back "active program". "normal --> 20" changes msg.payload to the preconfigured temperature levels (in my case 17 / 20 / 22). "influxDB" writes the result to my database. Starting from there I can post-preocess the results in Grafana, etc I am fine with this result but maybe there is a datapoint which provides this information without the need of my above workaround.     ...

Thanks for your attention Michael,   Smarthome as it is right now is more a marketing label or business model than something really useful. Who needs an app with some nice animations just to control the fridge? What's smart about doing the same thing you can do on the display of the fridge by an app (and sending your data around the universe...)?   Unfortunately Viessmann is leading towards the same direction with the new API (not the unofficial one, this was cool!). Really guys, no one really needs an app just to set the room temperature. You install it once, enjoy the nice animations and tell everybody how trendy your heating is. But after that you never use it again because as long as your house is warm you don't care and you have 1000 other apps to feed...   My vision of smarthome is different. To do something really smart you need to connect several devices of different manufacturers together and find algorithms for example to save energy or optimise the charging of your electric car depending on solar production. Those are very specific solutions which are different for every building. You need to implement the same optimization as it is done in large systems as heatings for factories and large buildings.   To achieve this, you need open and standardized API's of any manufacturer you use. To find the algorithms you need access to all available sensors and parameters and after some coding and tryout you will find some params more useful than others just for your specific system.   And now the important thing: you need feedback! For heatings it is the efficiency factor. In a lab environement you will stick energy counters to every pipe you find. In the real world this costs way more money than you will ever save. So you need a cheap and accurate way.   The flue temperature is the key factor of the efficiency of wallmount boilers like Vitodens (calorific effect). As Vitodens provides a flue temperature sensor (nice work Viessmann!) I use this to simulate the efficiency of the whole system. With some maths I get pretty accurate results. Just the effect of the LAS (which is minor cause of the limited heat capacity of air) and the standby losses (which are pretty small on Vitodens, again nice engineering...).   So, as soon as I get back access to this important sensor I will be able to thweak the algorithms further and make the Viessmann heating smarter and smarter... Without nice animations and apps but with the perfect temperature in every room at the absolute minimum of energy consumption... Big project (large historic house without any thermal insulation) but the results I already got are pretty exciting...   I really hope that the Viessmann API will head towards an open plattform and not staying focused on how much people will be willing to pay for which datapoint. Let us create some really smart solutions and you will be inspired and take Viessmann to the next level...   Thank you guys... ... Mehr anzeigen
