Modbus Integration of Sentron PAC3200T / Reading Register Values

Hello Community,

I’m at the very beginning with home assistant and I’m trying to integrate Sentron PAC3200T.

With help of some forum samples, I was able to read live values based on offset used as address

But now I would like to access the historical values, which are placed somehow in registers.

I’ve tried it in the same way as reading using addresses, but I’m getting implausible values.

I’ve no idea, how to use File/Offset/Address/Length in a proper way.

Thank’s a lot for your valuable help
