Server is DOWN   New heating season. New round of outages. When will this finally start to meet proper SLA goals? ... Mehr anzeigen

@yenz2222I'm not sure what you mean (google translation could be off). Tado is great and I don't need any further customization  via e.g. Home Assist.   But the communication between Tado and Vitodens is really poor, and I would like to improve that. Now it's just on/off control, nothing more. So you have on one side the Vitodens doing it's thing with the heating curve, and on the other side Tado doing it's thing with the thermostats. But they lack any form of communication which is off course bad. But I don't think there is anything I can do myself there?     ... Mehr anzeigen

In the end Viessmann exchanged my Vitodens 222-w model from 2021 to a 2023 model to fix the broken pump logic. Same as with @Wegi , I also had to lobby for 2 years to get this done.   Vicare Smart Climate was also taken back and exchanged by Viessmann for a Tado system due to the many ongoing issues with Smart Climate.   I'm now finally "ok" with my system. Tado is night and day difference compared to Vicare. And in combination with the new boiler the pump logic is correct and the boiler doesn't fire any longer when all valves are closed and no heating is required.   One very real downside still is the prehistoric communication between Tado and the Vitodens 222-W. Tado can only control it by on/off relay due to no support for OpenTherm or KM-Bus on the newer 2xx Vitodens. Hopefully this still can be rectified as especially during mid-seasons the setpoints will be easily reached and Tado can only control it by short-cycling on/off the heating at such times.   So whoever at Viessmann reads this: please sort out the interface to 3rd party thermostats! Either with an add-on OpenTherm adapter or an open interface to PlusBus which is easily accessible to 3rd parties! ... Mehr anzeigen

automatisch übersetzte Version:   Beunruhigende Menge an Fehlern, fehlende QA, versteckte Einstellungen und mehr   Vicare und Vicare Smart Climate wird immer schlimmer. Derzeit sind mir folgende Probleme bekannt:   - Überschreitung der gewünschten Raumtemperatur, oft um mehrere Grad. - Die manuelle Temperatureinstellung für die Raumregelung in Vicare funktioniert nicht mehr - Die Einstellung einer manuellen Temperatur im Absenkmodus heizt gemäß einer abgesenkten Heizkurve im Vergleich zum Normalmodus - Der Warmwassermodus in Viguide wird fälschlicherweise als aus angezeigt, obwohl er tatsächlich aktiv ist - Ein Timer für manuell eingestellte Temperaturen ist für OPTO2-Benutzer verfügbar, nicht jedoch für E3 (OneBase) - Vicare Plus ist für die früheren E3-Modelle (ab ca. 2020 - 2021) nicht vollständig verfügbar. Auch Intelligent Heat Control ist im Grunde genommen eine Rückmeldung der Raumtemperatur und hat keinen Platz als kostenpflichtige Premium-Funktion - Vicare war am Abend des 15. Februar erneut für mehrere Stunden nicht erreichbar. Ausfälle wie diese treten monatlich oder häufiger auf - Die Google Home Integration ist komplett kaputt und unbrauchbar - Wichtige Kesseleinstellungen, die das 3-Wege-Ventil und die Ein-/Ausschaltlogik der Kesselpumpe steuern, fehlen (frühere E3-Modelle) oder sind hinter einem Viguide pro/plus-Abonnement verborgen (neuere E3-Modelle, exklusiv für Händler) - Es gibt keinen allgemeinen Ein-/Ausschalter in der App für Benutzer von Vicare Smart Climate - Die Benachrichtigungsübersicht in Vicare enthält irrelevante Nachrichten und kann nicht gelöscht werden. - Meines Wissens gibt es keine Systembenachrichtigungen für kritische Ereignisse (z. B. Druckabfall oder ähnliches) - Für die nicht-deutschen Benutzer: viele Rechtschreibfehler und/oder Texte, die nicht in die richtige Sprache übersetzt sind (z. B. englische und deutsche Texte gemischt mit Niederländisch) - Für die nicht-deutschen Benutzer: kein Benutzer-Feedback-Formular in Vicare - Vicare zeigt Einstellungen in Bezug auf CO2-Werte an, aber ich habe keine CO2-Sensoren in meinem System. - Im Vergleich zu ähnlichen inländischen IoT-Produkten ist der Zugriff auf Vicare sehr langsam. Das liegt unter anderem daran, dass es keine direkte Verbindung zwischen der App und dem Heizkessel gibt. Alles passiert immer zuerst die Vicare-Server. - An bestimmten Stellen sind HTML-Tags sichtbar (z. B. Einstellung der Anzeigerichtung des Thermostats). Könnte auch exklusiv für nicht-deutsche Benutzer sein.   All dies wurde hier und bei Viessmann Belgien schon oft gepostet. Aber sehr wenig scheint sich zu verbessern. Zum größten Teil werden meine Mails oder Posts ignoriert (was bei diesem sicher wieder vorkommen wird). Und ständig tauchen neue Bugs oder Probleme auf. Es wird nur noch schlimmer.   Was braucht es, damit Viessmann den Weckruf erhält?! ... Mehr anzeigen

No OpenTherm or KM-Bus any more on the Vitodens 2xx, so you are vendor locked in to Viessmann thermostats only. And saying those are bad is an understatement. ... Mehr anzeigen

@Lala_OK Wo kann ich das finden?   Übrigens keine Entschuldigung von Viessmann, auf meine E-Mails nicht zu antworten ... Mehr anzeigen

@CustomerCareBen    Ich bekomme keine Antwort von Viessmann Belgien. Was kann ich sonst noch tun? ... Mehr anzeigen

So Viessmann thinks that not being able to properly control your heating (or in the case of child locked thermostats no control at all), for the most expensive system on the market, isn't a big issue? Wow.   Same goes for Viessmann Belgium btw, they don't even respond when asked about this bug.   Your corporate culture is so so very wrong. In every way.   The mistake I've made investing a lot of money into this. I would have felt better just burning a stack of cash. ... Mehr anzeigen

To add to this: the Vicare servers are highly unreliable and are down at least once a month.   It would already be a significant step forward if the communication between the Vicare app and the boiler would be local when on the home wifi. Not only would be it more reliable but also a lot faster. ... Mehr anzeigen

Why don't you hire some software testers instead of letting the high paying customers do it for you. ... Mehr anzeigen

I can confirm this bug.   I have 9 thermostats, 2 repeaters. Even the one with the strongest signal (consistent 50%+) has this. For me it's not that annoying. And there are a lot of other issues to fix as well. But I can imagine if you are a sensitive sleeper this can be annoying. ... Mehr anzeigen

@WegiI just now only read this thread. I have been fighting the same (and many other issues) for 2 years now.   As a Vicare Smart Climate user the problem is even worse. The minimum temperature only goes to 8°C. This is an example how my actual heating looks like on a cold day and when I set the heating to turn on only between 7h - 10.15h. The upper graph shows my supply water temperature (in red) and the return (in blue). The lower graph shows my gas usage.     Conclusion: 44% of the total gas usage was for nothing. All valves where completely shut outside of 7h - 10.15h. Next to that you have constant short cycling which is very bad for the boiler wear and a pump that is constantly running.   This kind of major technical flaws, as well as the reluctance and ignorance from Viessmann to fix this I have never seen before. And this happens in the most expensive residential gas heating system you can buy in Belgium! This is not even borderline criminal anymore, it actually IS criminal I think. Like a new dieselgate but then related to gas.   So because Viessmann does nothing I reported this to my local economic government department. Because of this they are now investigating Viessmann for greenwashing. And if Viessmann still does not come with a solution in the near future I will also take this to court. ... Mehr anzeigen

I take back what I said about it maybe being fixed. The bug is NOT fixed.   - Boiler keeps heating yet the setpoint is overshot by 0.7°C by now (no other rooms active) - The motor positions in Viguide stopped updating since this morning (for about 11 hours now) - The radiators still feel very warm so I presume the actual motor position is still "fully open". - The temperature will keep rising until I restart my communication module, as I type this it already went up another 0.1°.       @CustomerCareChris @Customer_Care when will this finally get fixed !!!!! I did not receive any update so far from Viessmann Belgium. Yet they are also notified of this since 28/12/2022.   How on earth can you ask so much money for this system yet leave it completely broken and unsupported !!!!! ... Mehr anzeigen

Right, because measuring or correcting the temperature is different in Belgium then it is in Germany. ... Mehr anzeigen

So basically what every other competitor already offers for ages Like this or this or this (page 8 below)  or this   shall I continue? ... Mehr anzeigen

True the valve positions do not update consistently in Viguide. But do the actual overshoots still occur on your side? ... Mehr anzeigen

I think this might have been resolved (about time). @Lala_OK can you confirm this on your side? ... Mehr anzeigen

It is true that the Vicare thermostats are now available in Google Home (long overdue), but it is anything but functional:   - they frequently disappear and then you have to add each one again (as described above) - they often time out when opening google Home, showing them wrongfully as offline - I created a Google Assistent shortcut to lower all my thermostasts and it just doesn't work properly. The Google Assistent shows errors when triggered, some thermostats do change temperature afterwards, some don't, ... - The Home/Away routines are NOT supported (probably so customers are forced to pay for geofencing in Vicare Plus if they want it)   So basically it's just another totally broken feature that their marketing department can start to abuse. ...
