I come over ISG integration which is based on modbus binding. Sadly, combination of Stiebel components I got to work with is not well covered by modbus-isg. I had to revert to traditional register based play.
Problem which I face currently is joining two registers:

These two are presented as 908 kWh and 44 MWh. Final number is
I had a look on available number formats (int32/uint32/float32 with swap) and I haven’t found any way to join above two into a desired number.
I’d appreciate any advice how to get it over.
