As I continue my tests, I realize that in fact it works with the latest version but with 2 hours of delays, i.e. that the integration shows 15:42 instead 17:42
Hello,
since the update to 2025.5.Beta I get the following error messages

I had last updated to 2025.5.0b7, the same message appeared with the previous beta of the 2025.5 version.
Maybe someone here has a tip.
Here is a temporary fix for the problem:

Just updated to 2025.5. removed completely the integration and the hacks custom component. The error remains the same

Hello,
thanks for the work that’s done here to keep our Vaillant compatible with HA.
I have a question not 100% related to HA but well with vaillant. I’m searching for a “working” VR921 for my cousin. with Working, i mean old hardware version that has been updated when vaillant changed their app or a recent hardware version S/N must be higher or equal to 212246xxxxxxxxNx. because if you have an older hardware that was not updated to myVaillant. You can’t use it anymore.
Best regards,
EL
hi guys,
is it possible to set the heating curve in our integration?
target:
entity_id: number.hjem_circuit_0_heating_curve
data:
value: 0.7
action: number.set_value
I need to change the curve itself - is that also possible like in the app?
The reason why I have to change this is that I have my office in the basement and the heating curve has to be set 20° higher in summer otherwise I won’t get the basement warm.
Or do you have a better idea?
This is how I change the heat curve.
Can I use this without a sensoCOMFORT? So only with an myVAILLANT connect module? Because if I already integrate into Homeassistant anyway, the use of an additional thermostat seems very redundant to me.

Hello,
the consumed energy entities are missing now… does anybody have the same problem?
My Energy entities are also missing, but my heatpump is new (since may 28) so i am just getting up to setup all things.
Hey. I’m using gateway that let me configure everything via MiGo app only (saunier). I have successfuly installed your integration even authentication goes without any problem. But after that - the end. No thermostat appeard in home assistant, not even one entity. Something changed after years? I have thelia condense boiler
Hi,
to be able to fix and make changes, I forked this integration and the supporting library.
It builds, installs and updates via HACS, has a (kind of) new HACS icon, has several updated libraries, has more test-data, has some more countries, two more sensors, …
I also updated the documentation and started to document the API itself.
It works for some weeks on my installation without any problems.
It can be installed in parallel with myPyllant.
If somebody is interested in collaborating, I’m happy to grant rights to the repositories:

Is Philipp (pdd) not open to collaboration on the original project?
Hi @romal the instructions in your README.md say to search for myvaillant in HACS but that brings you to the version you forked from. VaillantCloud doesn’t bring up anything. Could you update the install instructions?
Fixed. Thanks for the hint.
For anyone who is looking. Works perfect with below setup.
Vaillant arotherm split vwl 105/5
Vaillant MyVaillant connect vr 940f
I just ordered the Vaillant vra 42 for a clean installation and power the vr 940f directly from my Vaillant indoor hydraulic unit (vwl 57). This means the vr 940f doesn’t need and external power supply.
