Add sensors or parameters - how to (in this case the new power limitation)

[stefanovich1]

Hey friends,

ist there a documentation, on how to add parameters or sensors to the integration?
My attempt is to add the power limitation as a writable parameter tobe able to use it in automations.

Thanks

[stefanovich1]

Thanks I gues.
I dont get how a windows exe can fix the integartion on the HA?
The exe is flagged as suspicious....can you give furhter info on how this exe will fix this problem?

I would definitely not do anything with what Wanderx said, I don't trust that.
What you can do, is find the ID. Download the diagnostics before you change the parameter, change the parameter and download the diagnostics again. Find the difference between the 2 files and try to find the right parameter. Mention it here, and Benpru might add it to a future version.

Thanks for suggestion: Do you mean the datalogger diagnostics from the machine, right?

See https://github.com/BenPru/luxtronik and then the chapter about Support / Creating tickets.

Hello friends,

I did some investigation:
The Parameter ID 1158 is ON/OFF Limitation
The Parameter ID 1159 is the limitation in kW but in a weird dimension.
e.g. 2kW is listet as "20" and 1.1kw is listet as "11"

Is there a way to add it manualy via editor in HA?

[stefanovich1]

As far as I could research, BenPru's integration removed the possibility to add those parameters manually.
So I'm still stuck with this task.
Could anyone give me directions on:

• either how to add those parameters manually (if possible)
• or how to support BenPru to add those parameters (I am willing to contribute, but with very little experience)

Thanks

How to manually add Luxtronik parameters:

• Go to HACS
• Search for Luxtronik
• It will find 2 integrations with the name Luxtronik and the same icon. You basically need both.

1. The original Luxtronik integration by Bouni, last updated last year. URL ends with "hacs/repository/260169906"
2. The integration in this repository by BenPru, currently at version 2024.9.23-Beta. URL ends with "hacs/repository/420733339"

• You will have already downloaded and installed integration 2.
• Download and Install the integration 1. It will install the integration in custom_components/luxtronik.
  (The BenPru integration 2. in this repository has been installed to custom_components/luxtronik2)
• Integration 1. cannot be configured via the HA UI: you need to configure everything via YAML.
• The Hacs page of the integration 1. (URL ends with "hacs.repository/260169906") describes how to configure via YAML the connection to the Heatpump, and how to add sensors for parameters that are not part of integration 2.

Should you have problem adding the sensors or getting things to work with the integration 1. , you'll need to ask for support at that integration: https://github.com/Bouni/luxtronik/issues

The Parameter ID 1158 is ON/OFF Limitation
The Parameter ID 1159 is the limitation in kW but in a weird dimension.
Firmware *.90 >=

@stefanovich1 Great, thank you very much.
Please let me release a new stable and after that I can have a look at the new values.
Unfortunately my heatpump has no new firmware (*.90) and I can't test it.

Hi,

I think these parameters are very interesting not just as sensors but also as writable. At the end I would be possible to adjust the heat pump power limit to the available power from PV for example.
I have no idea how to change these parameters via HA. But changing this via the UI of the Luxtronik is not an option.

There is a new firmware available which adds support for a HEMS based on Solar Manager .
See some infos at Link
Up to now i have no problems using this firmware with the latest integration 2024.9.30

EDIT: see this issue

[V3.90.1-12327]

• Allgemeine Verbesserungen und Optimierungen der Wärmepumpenregelung
• Integration Smart Home Schnittstelle (SHI) für die Anbindungen des Solar Managers (HEMS)

Hey people!
I would like to help wherever I can. I have a suggestion for the Sensors below.
The Sensors only apply when "smart grid" is active.
This switch is also not available in the integration....should we add this also?
