Warmwater set target temperature

[jumahrauf]

Hello,
I am using 2024.10.5-Beta with luxtronik firmware V3.90.1.

Actually I am not able to set the warmwater target temperature.
Where can I see in a log what the current problem is?

Settings --> System --> Logs.
Then, using the search-bar at the top of the page, search for "luxtronik"

In my case (SWCV92H3) with firmware 3.90.1 the target temperature is 49° and the coverage temperatur of the heat pump is shown as 75° (at the control panel). In HA the target temperature is then shown with 75°.
Maybe the wrong parameter ID is used?
In the list of parameters there exist
2: Celsius("ID_Einst_BWS_akt", True),
and
105: Celsius("ID_Soll_BWS_akt", True),

The fixed 75° for the coverage temperature seems to be a bug in the 3.90.1. Usally this value should be the same as the target temperatur.

Attached the temperatures in the control panel - with 3.90.1 the second one is shown with 75°, in HA then the hot water target temperature is then shown with 75° without possibility to change (the target temperature in the panel - the first one - is still 49°). If you want to change the target temperature you change the first one, the second one change automatically to the same temperature.

When I create a "Entities Card" tile for "DHW Target"on a dashboard, and modify its value, I can observe that the value is changed on the heatpump.
So for me setting the temperature still works OK.
I am using firmware V3.79.

Note: I do also get the warning " /config/custom_components/luxtronik2/coordinator.py:121: RuntimeWarning: coroutine 'DataUpdateCoordinator.async_request_refresh' was never awaited self.async_request_refresh() ", but as I said, the value is still correctly changed on the heatpump. So the warning does not mean it does not work.

This, combined with the post by @blue-bean suggests that the problem that the may be in the 3.90.1 firmware and not in this luxtronik integration.

Or are you suggesting that starting with V3.90.1 the luxtronik behavior changed, and that starting with that version the water temperature should be changed by changing
105: Celsius("ID_Soll_BWS_akt", True),
instead of
2: Celsius("ID_Einst_BWS_akt", True) ?
Did you try writing parameter 105: Celsius("ID_Soll_BWS_akt", True), and does that change the hot water temperature on the heatpump?

No, i don't know how to do this.
Did you try to set hot target temperature by 105: Celsius("ID_Soll_BWS_akt", True) using firmware 3.79?
