Volume Flow

[marcus198006]

Hello, is it possible to get the current volume flow of the water circuit? The hydraulic station shows me the value, I wonder if it is possible to get it as an entity?

Thanks

Is that possible in the myVAILLANT app? If not, it's unlikely that it can be added.

I can confirm that it is not possible in the myVAILLANT App.

Sensocomfort get's it via eBus from the Arotherm, but I have never seen it in the app.

Hi Robert, ok danke, aber wie hast du den Volumenstrom vom eBUS nach HA bekommen (also ich vermute, dass du das hast)?

[rmalbrecht]

Hi,
es gibt verschiedene eBus-Adapter, mit denen man an die interne Kommunikation zwischen den Vaillant Komponenten rankommt.

Signalkrafts Addon ist viel "einfacher" (man muss die Heizung nicht aufschrauben) und stabiler. Dafür ist die interne Kommunikation informativer.

Nice! Danke

eBus is a really deep rabbit hole. And eBus access can properly confuse (and maybe even damage) your heating.

Not promising and that's my first impression by reading your blok. I will try to understand it and if I conclude that it is too risky, i want go further down that road.
I also requested Vaillant to get dQ/dt into the API. First respond was that it is only available for professionals with professional software. Not proper reason to me. They check it. Let's see.

is volume flow the same as volume temperatur?
in the old vaillant integration it was possible to get the volume temperatur. Is it possible to get in via myvaillant - i had to upgrade yesterday.

[rmalbrecht]

What is volume temperature? Volume flow is the amount of liters the pump is pushing through the underfloor heating pipes.

Vorlauftemperatur in German 🙈

lists the entities. Maybe you are looking for

** Home Circuit 0 Current Flow Temperature**

For my installation, this is the supply temperature. For heating it's around 22°. For hot water, it's changing a lot.
