Set of the target hot water temperature not working.

[tunguskar]

the reading of the hot water temperature is pretty fine. But when I want to set it with:

service: luxtronik.write
data:
  parameter: ID_Soll_BWS_akt
  value: "60.0"

The value does not change. Do I have to set anything on the heat pump?

[mkubu]

Could you pls share excerpt of config how do you read the value?

[tunguskar]

- platform: luxtronik
  sensors:
    - group: calculations
      id: ID_WEB_Einst_BWS_akt
      friendly_name: Temperatur Warmwasser Soll
      icon: mdi:thermometer

Sorry for the late reply!

The parameter should be writable: https://github.com/Bouni/python-luxtronik/blob/main/luxtronik/parameters.py#LL139C51-L139C51

Do you see any kind of errors in the logs?

[Bouni]

I just check this and for me it seems to work!?

Hi,
I guess I have the same problem. I found out that I change "Deckung WP" instead of "Warmwasser soll" after setting the temperature via Home Assistent.

I have a Novelan LADV9 with Firmware V3.86.1

Hallo, ich glaube, ich habe das gleiche Problem. Ich habe herausgefunden, dass ich „Deckung WP“ statt „Warmwasser soll“ ändere, nachdem ich die Temperatur über den Home Assistent eingestellt habe.

Ich habe einen Novelan LADV9 mit Firmware V3.86.1

Hast du das mit der Deckung WP in den griff bekommen?

@PVAnfaenger

unfortunatelly I have no soultion and there was no feedback from any developer or user.

Kind regards

Hello
I tried this about 4 weeks ago, I would like to implement the whole thing in Node Red because of the overview. When I did this test, he also wrote it in the "Deckung WP" whatever "Deckung" means in this place?
Do you only do your tests when you are at home or should it be possible to check the values directly online via https://www.heatpump24.com/?
As I am currently at the beginning of the automation, I have set static blocking times in the controller for the domestic hot water supply from 9-12 pm so that this is only done during the day. Are there also variables where I can influence these blocking times? Or is there a complete catalog somewhere of all the variables that can be read/written to?

Thank you

[Bouni]

@PVAnfaenger

Is the name "Deckung WP" from the webinterface?

Or is there a complete catalog somewhere of all the variables that can be read/written to?

Kind of, you can install the python-luxtronik module (pip install python-luxtronik) on a computer that runs python (can be the same that runs HA). That gives you the ability to use the CLI:

luxtronik dump 192.168.178.26

That returns a long list of all Parameters, Calculations and Visibilities like this:

Hello @Bouni ,
Yes, the value “Deckung WP” is on the web interface but also on the heat pump controller display, to be found under Settings/Hot water/Temperature see attached picture.

My HA is installed directly on the Lenovo Think Center and not in a container. How do I get to the CLI? Or is the CLI the same as the SSH terminal?

thank you

please give this a try:

pip3 install python-luxtronik

Hello @tunguskar thank you, I overlooked that.
I have tried with the following result.

Yesterday, I spent some time on the subject for the first time in ages. It has now worked in NodeRed to read and write values. I read a lot again and stumbled across @benpr project. Maybe I should follow that one!?
