Isn't it possible to just change the target temperature for heating and/or warm water?

• luxtronik2.0.parameters.warmwater_temperature
• luxtronik2.0.parameters.heating_temperature

If I change warmwater_temperature my Luxtronik does not change the target temperature for warmwater ("Wunschwert") but only the "Deckung WP" value in the menu on the display. If "Deckung WP" is set lower than "Wunschwert" the heat pump will also try to reach "Wunschwert".

Has anybody a solution to set the warmwater target temperature via the adapter?

There is even a parameter 'luxtronik2.0.parameters.temperature_hot_water_target' but it's read-only.

I finally found a way to set 'luxtronik2.0.parameters.temperature_hot_water_target' and it does exactly what I guessed and what I was looking for (set the real target temperature "Wunschwert").
I will try to open a pull request...I never did this before :-)

BTW the second state (luxtronik2.0.parameters.heating_temperature) is not the actual temperature, but rather the offset as you would also configure it on the display of the heatpump.

to avoid the heatpump start heating the warmwater I used "Sperrzeiten". So the taget temperature would only work to start the heatpump outside the defined Sperrzeiten. The ID_Einst_Warmwasser_extra would allow start the system immidiatly.

[MiniBlister]

would this be an "easy" fix or does this need more time to implement? Can I help doing it?

[UncleSamSwiss]

Unfortunately, I have currently absolutely no time. So, if you can create a PR, that would be awesome; otherwise this issue will be on my list of todos as soon as I get time to work on ioBroker again.

There is a python luxtronik script availabe which specify the following parameter

1052: Unknown("ID_Einst_Warmwasser_extra")

Hi @MiniBlister,
Could you provide the link to that python script please?

[MiniBlister]

sure: Bouni/python-luxtronik

Hm, I was able to set the parameter 1052 at my heatpump from "0" to "1" during Sperrzeit and during open hours, but with no effect! But maybe my Lux/Firmware does not support it.
Are you sure this one really fires a hotwater cycle? I cannot find any explantation for it.
You could simply try yourself as a first step by following the installation and commands here: https://pypi.org/project/luxtronik/

But: why not using the already existing "heating_operation_mode"?

        heating_operation_mode: {
            role: 'value',
            type: 'number',
            writeName: 'heating_operation_mode',
            states: {
                0: 'Automatik',
                1: 'Zusatzheizung',
                2: 'Party',
                3: 'Ferien',
                4: 'Aus',
            },
        },

'Party (=Continuous operation)' should work during Sperrzeit, you only need to take care to set it back to normal when the sun disappears:

[MiniBlister]

thanks for your help. I did run the python script and you are right, it does not chance the mode and heating does not start.
Party mode seems to be the only way.

Any plans to implement the timer functions? I do not need all of them but heatingOperationTimerTableWeek would help for my automation process
