This app is not yet available for us (Belgium). However it is a huge information. I think I will stop my dev and wait for this new app.
I found that: https://upgrade.myvaillant.com/, it sounds itâs already possible for some countries.
The android app is here:https://play.google.com/store/apps/details?id=com.vaillantgroup.enduserapp.vaillant
I hope there will be some API documentation⌠
Wait and see
But it is only for sensoApp ? Or also for Multimatic ?
For what i read, both.
I already installed the app but cant start the migration without Vaillants auths. Looks like they send you a sms when u can do it.
It is also for multimatic ? Now i can not install this on my smartphoneâŚI ask by opinion from multimatic app and Polish Vaillant send me response that now i can not upgrade because new version is in testâŚ
Now in POLAND i can not install it.
Well, french version doesnât mention mutlimatic at all (as well as english version), but there is a mention of multimatic in german version, see here: myVAILLANT App | Vaillant
For Multimatic show that upgrade will be availeble from Q1 2022 
Iâve installed the multimatic, but how can i see all the values now?
for example outside temperature and if the system is in cooling mode?
I dont see any Entities for example.
You should see devices and entities in the integration screen
This is what I see
Hi all,
same question from me, I don´t see any devices and entities!
Installation of integration was OK, asking for password and so on was successful.
I just using the SensoAPP because I have an VAILLANT VR 921 sensoNET as an Gateway and this device COMFORT VRC 720 for controlling of the heating system.
This is exactly the same problem I have. And I also have the axact same setup
multimatic integration doesnât support sensoApp, while they are quite close, multimatic and sensoApp are different API
Ok, but how I get this work for the sensoApp, I would like to control also my Vaillant heating system until this new myVaillant starts up.
This is not supported, and I think it wonât be supported until âmyVaillantâ is released
Ok,
I gone this all through so MultiAPP is for the old heating systems and SensoAPP for the new ones and now they are inviting a new app that shut combine all devices old and new!
Has somebody a time schedule when this new App âmyVaillantâ will be supported by Home Assistant??
The next winter is coming and I would combine my heating system with my smart thermostat and so on.
In the App store its already released and Vaillant is starting to upgrade the old systems and there is no way back anymore.
BR
Ok thank you, i thought it was working in this version looking at the github repo
Actually, this is almost the same, only difference is VRC700 (multimatic) and VRC720 (sensoAPP).
There is no schedule at my side, only thing I know is my system (multimatic + ambisense) will be migrated Q1 2023, I hope somebody will do something before that
when I change Vailland integration to Multimatic integration I`ve got problem with entitiesâŚ
as below my variables goes to unavaiable and there is no connection⌠any one got the same problem?
see issue #48. for me itâs more stable the last days. but problem still occurs.
