Is it possible to add extra entities

[stevenvanhoof]

I use this integration for a few months now for a new installed Arotherm Plus 55/6 heatpump with VWZ AI. It helps me with configuring the Arotherm. I'm curious if it's possible to add extra entities (if they are even available in the Vaillant cloud environment). For example I am looking for the inlet/return (T.0.41) and outlet/flow (T.0.40 in the VWZ AI) water temperature of the Arotherm itself and maybe the desired flowtemp. I think the displayed System Flow temperature is the T.1.70 value. I'm not sure, but assume it uses the external sysflow sensor te measure this value (i taped it on the pipework), so it is not that reliable as the T.0.41 and T.0.40 values that use the internal sensors of the heatpump. I downloaded the Vaillant pro service app and these values appear in the demo-modus, I can't add my own heatpump because I don't have an installers account.

Any toughts on this?
