Modbus (Waveshare RS485) to Deye Inverter - First reading of the day wrong

Hi, I am struggling with the following problem. I connected my Deye Inverter via RS485 Waveshare TCP Connector and configured everythign. So far it’s working. But - the first reading of the day is wrong.

As you can see, the Inverter seems to be powerd down at night, so there are no readings. The first reading of the day is the last reading of yesterday.

Any ideas how I can fix this?
