Fronius SmartMeter - two pieces for measuring heat pump consumption

A Fronius inverter SymoGen24 Plus is being installed.

A Fronius SmartMeter is placed here at the feed-in point so that the household consumption as well as the surplus can be measured/calculated anyway.
Now I would like to install a second SmartMeter directly in front of the heat pump.
The goal is to be able to display its consumption as well.
Is this even possible?
Unfortunately, there is little information on this.
A measurement should be possible, but the measured consumption of the second meter is simply to be added to the household consumption, which leads to an incorrect value.

That’s doable. Whether it makes sense is another question.

What kind of heat pump will it be?

Not yet certain. Possibly a Nibe from the S series. Would like to have the consumption of the heat pump displayed, though.

Almost all heat pumps have integrated meters. Some have their own apps, some have interfaces to inverters and co.

There is a video from Fronius as a webinar that explains how to integrate additional consumers. You might want to have a look at it.

You can generally measure that more or less well with Shellys and track it in the app.
