Guide how to use the data for the energy page in HA

[ThomWee]

Thanks for this extension.

Describe the bug I'm trying to configure the energy tab in my HA making use of the current Wh produced by my panels. But somehow the data displayed are never matching the output. I'm new to this topic, so maybe I'm understanding something wrong.

To Reproduce My HA instance is running as a docker image on my raspberry pi. HA is running as version 2024.1.5 and your extension in version 0.1.4. Language I'm using is German.

I did configure the energy page to display Port 1/2 DC power.

But the final results are just wrong. I'm having a 800Wh solar installation and can't make 8kWh.

It would be nice to get some hints how to correct setup HA displaying my data.

This is if I show the extension data on the dashboard.

Your screenshot looks correct. The first image shows the total number of kW/h for the time from 22.02.2024 - 26.02.2024 (see upper right corner).

So the 8.8kW/h are not for one day but for the entire week. You can change the view by clicking on the small calendar icon and select, e.g. "Today".

Edit: Also bear in mind that you are using the DC values, which might be slightly higher than the actual AC values reported by the Hoymiles HMS-XXXXW-T2 AC daily energy sensor

@suaveolent thanks for reply. I thought the view in the upper right corner are the actual values from right now, because of the nice animation. When checking the history for AC daily energy, the board shows me that this value is always 0 or like in my second screenshot Unknown. Do I need to tweak something in the extension?

It works if you use the daily AC energy:

To get the same animation for live data you can use the following plugin: https://github.com/flixlix/power-flow-card-plus

Yes, I noticed that the power was 0 or unknown before. Are you running the latest version of the integration (v0.1.4)?

Can you maybe navigate to Settings > Devices & Services > Hoymiles HMS-XXXXW-T2 > Hoymiles HMS-XXXXW-T2

and see if the sensor "AC power" shows up (entity id should be sensor.hoymiles_hms_xxxxw_t2_ac_power)?

[ThomWee]

I can see this entity but no data are present, just 0. Can I somehow create logs or some printout helping to debug my problem?

[ThomWee]

And yes I'm using 0.1.4

Are you familiar with CLI / python pip?

You can try running the get-real-data-new request from the underlying library itself and see if the dtu_power: is returned. See:

https://github.com/suaveolent/hoymiles-wifi

e.g.

hoymiles-wifi --host <IP-Address or Hostname of DTU> get-real-data-new

Also which SW/HW version does your DTU/inverter have and which model do you have?

[ThomWee]

I know how to use CLI and python pip. I got these information using hoymiles-wifi from inside the home assistant container.

[suaveolent]

Thanks, It seems like you have a completely different HW/SW version than I have and the dtu_power is missing in your response.

Have you already upgraded to latest DTU version (V00.01.11 for me)?

This might fix your problem. Otherwise I might also be able to fix it in a future update using the active_power of sgs_data.

[ThomWee]

Hmm, I updated my DTU now from SW version 00.03.12 to 00.03.13 ... now I get way less data

[ThomWee]

okay waiting and retrying finally presented me some new data

[suaveolent]

Thanks, seems like this info is still not provided with your DTU. I will fix it with next version.

Btw: Which inverter model do you have?

[ThomWee]

Thanks. I added the active_power sensor by hand now. Let's see tomorrow if there are data send to my HA sensors.

[suaveolent]

Ah that explains everything.

You are using the DTU Wlite and not the integrated DTU of the HMS… W series.

The integration was developed for the W series.

However, it seems that most functionality is indeed the same. I will cope for that in the next release. Thanks for sharing.

[suaveolent]

Pushed fix to main, will be fixed with next release.
