Is it possible to integrate a Toshiba Estia heat pump?

I think I have a live data link now with my Estia heat pump… I thought that there should be a continous data-link, but it seems that only data is pushed when requested. So I can now request data to port 502. Big challange now is how to adress all the elements in Home Assistant…

As a first attempt, I would like to be able to read the following register and show it as a sensor in H.A.
Modbus register: 40022
Only read value
What: Water inlet temperature
IP Adress of Modbus RTU/ASCI over TCP/IP: 192.168.1.9
All registers are of the type: 16-bit signed holding register, in standard Modbus’ big endian notation.

How should I add this in a .yaml file to be able to read this value and safe it as a “sensor”?
