Analytics: Adapt GF Dashboard for ventilation correlation values

[Oggy512]

I can't remember if it was an issue or a discussion, but we had the topic of ventilation settings/states recently here. I wasn't the only one, who had problems with a loud ventilation system and other users recommended solutions like filter or grid cleaning.
One ventilation/noise related sensorvalue is the ventilationspeed (Drehzahl =^ ZULUFT_SOLL and ABLUFT_SOLL), however that value is only comparable, if the corresponding volume is also taken into consideration.
I.e. my exhaust ventilation speed is 35 Hz, which seems to be higher then other values, but my exhaust volume is 160 m³/h, which seems also to be higher then others. Having this correlation in mind, the speed looks not too high. ChatGPT also says a ventilation speed of 35-40 Hz with 160 m³/h is good.

Long story short:
Any ideas to have a dashboard/visualiziation whch shows the ventilation volume and the speed?

We could use a sankey card to visualize the ZULUFT, FORTLUFT and ABLUFT an color it based on community knowledge of what is good or bad 🤷‍♂️

We can use some sort of efficiency factor:

Oh, I like the graphics, it looks nice and I also like the efficency idea :-)
However, those are two different approches:

1. is the comparission of the own values with the communitiy (and the avg, min, max etc). That gives an estimate, if the own values are reasonable.

2. My initial question was more to display the relation between the actual setting, which one can adjust in m³/l and the actual value which the heatpump uses to fulfill this user setting. That value is also the same wich is shown in the sensor, which is in Hz, a different unit.
   To be able to better compare the own values in Hz with others, it's important to know which setting is it based on. It makes a difference if a ventilator runs with 35 Hz to make 160 m3/h or 110 m³/h ;-)

And cave: The FORTLUFT ventilator in the heatpump is the ventilation for the compressor. That ventilator starts and stops with the compressor, it has nothing to do with the acutal ventilation of the house like ZULUFT and ABLUFT. Just saying, since the wording is included in the picture above :-)

Are you sure about FORTLUFT?

The big fan for FORTLUFT results in less power needed for the small one it seems 🤷‍♂️

[Oggy512]

Well, thats what the Stiebel technician told me, when we were investigating the ventilationsystem. He said the FORTLUFT ventilator is bigger and more powerfull then the other two (ZU/AB) and only operates to cool the comporessor.

That sounded reasonable for me and based on the sensor values, it fits with my heatpump behaviour:

My comporessorstarts correlate with the on/off of the FORTLUFT

I confirm also fortluf is link to the blower for the evaporator of the compressor. And start with the compressor. Plus when the fortluf is on abluf goes down because a part of the flow is redirected to increase efficiency. At least on thz 5.5 eco

In total there is 3 fans in the system

Sorry for deleting the Post @Sulik7761 the github mobile App sucks 🥲 can you please post the picture again?

It is not the 5.5 eco but 504. Similar design

No problem :)

i did this several years ago (when I was on fhem for hp monitoring).
However i ditched the grafana dashboard and dont have it anywhere in backups..
