Writing a component for Luxtronik Heatpumps

ChrisM1983 · October 22, 2025, 3:38pm

Well, I was using the Alpha Home stuff… when I decoupled that, and not let Alpha Home mess around with it, I got it to work. (I don’t have a RBE).

I’m still stuck with this configuration problem.

Any help would be appreciated.

We have two sensors in this integration:
luxtronik_341022_0297_heat_source_input_temperature
luxtronik_341022_0297_heat_source_output_temperature

Can the translation (name) for this two be corrected in future releases?
Either name both "Wärmequelle … " or both "Heizquelle … " in German.
Or is this something I can change by myself?

Best
Martin

Hello,
i am using the Luxtronik Integration by BenPru.

This Integration has a Controll called DHW Domestic Water.

With Mode you can select the operation mode oft the HotWater HeatPump=Automatic Mode, Performance=PartyMode

Is there a way extract this Mode Button?
I dont need the rest of the control.

In the manual it is described to use a service.
But not where to Implement it.

In order to change parameters on the Luxtronik conroller, you can use the following service:

Domain: luxtronik2
Service: write
Service Data: {“parameter”: “ID_Ba_Hz_akt”, “value”: “Automatic”}


Can you please help me?

It’s not exactly clear to me what you want to achieve.

The entity had a number of attributes you can use:

You can use a template to retrieve these attributes using a template sensor.

There are actions to control the operating mode. Actions can be used in an automation.

I hope this points you in the right direction and if not, let us know.

I have made a feature request

AJediIAm · December 3, 2025, 5:33pm

This is a request to all users of the BenPru 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:
It might not work as expected. 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.

Which parameter changes work for you?
