Feedback request: does changing the Heating Target temperature (using the Heat thermostat tile) work for you?

[rhammen]

This is a request to all users of this integration.

With #346 , the implementation was changed such that changing the target room temperature using the thermostat, should change the target luxtronik room temperature. (parameter 1148, new in approx. firmware v3.90)
Goal of this is to be able to change the target room temperature using this integration.
If this works correctly, then when you increase the target room temperature using the thermostat card, the target return flow temperature should also increase.

My question is: does this work for you?

Why do I ask:
For me, it does not work. :-(
I can change the Heating Target Room Temperature using the thermostat tile to e.g. 30 or 35 C, but the return flow temperature does not change at all. When I change the target room temperature on the RBE itself, the target return flow temperture does change correctly.
So for me, changing the parameter 1148 does not result in the target room temperature on the RBE being changed.

I did some tests and it looks like the heating target works as intended.

On wednesday, you can see how the heat flow in is opposite from the measured temperature. I assume that this is because of the room impact factor.
Maybe I should make a slight adjustment to the heatcurve to dail in the temperature a bit better.

On thursday, I lowered the room thermostat target via home assistant. I made a large change to ensure the effects would be observable. I observed that the physical room thermostat (RBE+) adopted the new temperature as well.
The heat flow in target adjusted accordingly. Because there was enough heat in the house, the heatpump didn't run that day. Also the wife confirmed the temperature had dropped at the end of the day, so I had to raise the temperature a bit again.

On friday, the heatpump had to run for a bit. Besides the idle time on thurday, I didn't see a notable change in the power consumption. The heat flow in target is enough evidence for me that the temperature change had the desired effect.

I'm using number.luxtronik_230305_047_heating_target_correction for correcting the target temperature.
My thermostat does not set a temperature request, but an offset on the heating curves.
The above parameter is another offset on the heating curves so the physical jog wheel still works.

Edit: I have firmware version V1.88.3 after updating the firmware, so probably this older (2013) device

Thanks for the input.
I expect that there are multiple solutions and not all solutions will for all heatpumps and firmware versions.

For me it works!
I have an alpha-innotec heatpump

I tried the target correction and noticed a different effect. Instead of affecting the heat flow in, it only affects the heat flow out.

Here you can see that I adjusted the correction by 2C. The heat flow out dropped by a bit more.

Great 👏. Next to the Luxtronik integration I was also using the myUplink integration because I couldn't change the RBE target temperature. With this I finally can ❤️ .

I'm using an Alpha Innotec Hybrox with latest firmware.

Question
In the config options, I had to set the Room thermostat (from Luxtronik) as a Sensor ID to get the thermostat card to fully work (now shows Current tempreature). Is this statement wrong? Or is something wrong on my end?

[Linos88]

Changing the parameter 1148 has no effect. This is explainable for me, because in my Luxtronik 2 (1.86.x, BJ2013) the room thermostat operation is deactivated.

I set a correction with "_0130_heating_target_correction". This changes the return_soll as desired and should be the logic layer as well. I use it exclusively as a "photovoltaic function" and as a "start delay"

@rhammen do you have enough information?
If so, you can assign the issue to me so I can document it.
