It looks like CurrentCompressorUtil value is in the wrong dimensions

[pieterb26]

Since an update to the latest version of Ebusd, the CurrentCompressorUtil value is for me in the wrong dimensions.
When I'm heating water it should be 60%, it shows only 6% and now I'm running cooling on 0,75%, but it should be 7,5%.

I'm using the - "--configpath=https://ebus.github.io/next/" files.
So I can't change the datatype like mentioned in: #396

Decision to change was made surrounding this discussion: #481 (comment)

The repo presumably in operation (https://ebus.github.io/next/) actually uses the correct D2C datatype:

r,,,CurrentCompressorUtil,current compressor utilization,,,b51a,05ff3225,ign,,IGN:3,,,,value,,D2C,,%,

Here it seems there is factor of 10 error, maybe an incorrectly set divider?

What can I do?

@pieterb26 You could see if RunDataCompressorSpeed is an alternative for you (I've been using that).

But judging from the positive remarks in the #396 issue you linked, one could conclude that the config is actually correct now, while it was not before.

Could it be possible that you have a setting in your dashboard that corrected the value, dividing by 10 or 16? In that case changing that correction could resolve the problem (I do not know what kind of dashboard you use, so I'm guessing).

Edit: I could finally test it with the heat pump and the current config is correct: compressor speed at 30 rps, CurrentCompressorUtil gave 25%. So the problem should not be in this repo!

Maybe double-check the CSV definition used for CurrentCompressorUtil.

ebusctl find -f CurrentCompressorUtil

If you can't access the command line you could also connect to ebusd using netcat (e.g. provided by the 'Terminal & SSH' addon in HA).

nc x.x.x.x 8888
(substitute x.x.x.x with IP address of your ebusd server)

then:

find -f CurrentCompressorUtil

and post the output here.

this is the output:

For this one I don't see any value:

And it's not only in the dashboard, but also direct on the mqtt device, so no dividing. But maybe it's in the mqtt-hassio.cfg?

Interesting, judging from the IDs you seem to have quite different units. What model is the heat pump? Maybe it indeed encodes the CurrentCompressorUtil differently? I would suggest to switch to local ebusd configs (CSV), so you can adjust this.

I have a Vaillant Arotherm VWL 85/2 + VWZ AI + VWZ MEH60 + VRC700.
Maybe it's because it's an older model?

[chrizzzp]

Yes, very likely. Vaillant could have changed the data type from D1B to D2C in the newer models. The question is which models are also affected?

So this would require a specific condition in the current 08.hmu.csv or a separate config. If you use online ebusd config I would suggest to switch to local CSVs to fix the issue for you.
