Describe the bug

Incorrect values are reported for multiple sensors i.e.: Load Consumption Today. After integration restart correct values are reported for a short time but after short time values drift away again.
Attaching graph showing incorrect values over time
Solax-incorrect values
Few minutes after 10PM integration was restarted and value jumped from a bit over 4kWh to over 7kWh.
Value should reset at midnight ( as this is daily consumption) but it does not.
Attaching second graph from different source ( solarman) but same sensor showing how correct values should look like:
Solarman - correct values
