After Switch to myvaillant: no system data

[Tharanis]

Hello,

i hope you can understand my english, sorry...

i use this components:
-Vaillant VC 15 CS/1-7 ecoTEC exclusive
-Vaillant sensoNET VR 921

i have to begin a few month in the past:
in the last few month i´d use the multimatic homeassistant-integration, because i had to use the Vaillant app multimatic. In the same time i registered my Vaillant Components at the myvaillant-system without to use the new myvaillant-app.

In the last few days i got two emails from vaillant to switch from my old system multimatic to myvaillant. Yesterday (Friday) i migrate my system to use the myvaillant-system with an Update from vaillant for my Vaillant sensoNET VR 921. Since this step i only can use the new myvaillant-app for my Vaillant VC 15 CS/1-7 ecoTEC exclusive.

The homeassistant-Integration multimatic did not work anymore, so i installed this promising mypyllant-component-Integration.
I can use the same login and i got no errors, but also no data from my vaillant-system. So i tried to get some debug-infos:

Is there anybody with the same problem? Is there anybody who migrate too from the old to the new vaillant system?

I had the hope that something would fix over night,

My hope now is that someone here might have some advice and otherwise that Vaillant might have to do a few more clicks manually and this will happen at the beginning of next week.

Otherwise I'm unfortunately without an idea.

Thank you for your help.

There's a related issue here, maybe you can help find a solution there!

[Tharanis]

Thank you, i also read the https://github.com/signalkraft/mypyllant-component/issues/86.

In the first posting i didn´t tell, that i have also a VRC700, i thought, that this is not relevant. Now i know, this is perhaps the major-Problem in my vaillant-Setting... sorry.

I got better logs now, if they are helpful. My logs has also the string:

DEBUG (MainThread) [myPyllant.api] Starting request TraceRequestStartParams(method='GET', url=URL('https://api.vaillant-group.com/service-connected-control/end-user-app-api/v1/systems/[key deleted]/vrc700'), headers=<CIMultiDict('Authorization':

So, If it is helpful, i could upload a file. Perhaps with attached file(?). What Information is helpful and what informations can i delete in the normal case. I´m a newbie at github and i dont want, that anybody could read too much informations...

Please try https://github.com/signalkraft/mypyllant-component/releases/tag/v0.7.2b1 by enabling beta releases in HACS. If you have any issues, please use the ticket I linked.

[Tharanis]

Thank you very much.
I´ve installed the beta-Version through Hacs (v.0.7.2b1). After the nessesary Restart of HA my Vaillant Components appear immediately.

Do you need any logs about it?

Because of my first use of your Component i can´t say if all functions are ok, but it looks ok! Thank you again!

To read the state of my vaiullant-Components seems to work. I tested to make some changes to the vaillant-components trough homeassistant and got error-messages. I tried to upload this error-messages without any personal informatiuons from me. I hope the error-Messages are helpful. Thank you.

I'm responding to this thread though three months on the issues may be different.
My AroTHERM ASHP was installed on 16 April with a VR940f MyVaillant CONNECT gateway. I could not read energy data via the Vaillant app or via mypyllant till 2 May when everything started working. From the forums I gather that Vaillant have had server problems for almost exactly this period and possibly problems with app versions before 2.17. mypyllant is now reading daily energy data and the app is displaying weekly and monthly data as well.

All being well OvO is due to go live with a variable electricity tariff this week for Vaillant customers with smart meters. I don't know how they extract energy consumption data but I would expect that they must read the accumulated energy total that can be seen in the controller. I do not believe that mypyllant can read this information directly but it is an important variable. I also believe that the MyVaillaint CONNECT allows access to more information than the older SensoNET. I'm just a newbie but would an expert like to comment here? Will future versions of mypyllant be able to extend the list of variables that it can read?

[dr-dongle]

PS: I am pretty sure that the Vaillant app isn't reading the cumulative energy figure but is adding up daily figures to get week and monthly totals. I also believe that Vaillant are either about to make changes to their API or have done so very recently in order for discounted heat tariffs to work.

A gateway firmware update was pushed out last night, in the UK at least (0404.01.19)
