Visualize Target Temperature of Stiebel WWK Hot Water Heatpump

[AAPohl]

Hey,
I am trying to implement a stiebel WWK integration. So far, I managed to create a custom driver with a UI:

I visualize currentTemperature, current TargetTemperature Compressor On/Off.

Since I cannot set SG_Ready via this API, I plan to set target temperature. Therefore, der Target Temperatur should be more prominent than the small value.

Can I use the session soc limit for that? Make the Slider Readonly from UI to only visualize the value?
