ValueError: Value 0 failed validation (>0)

Hello,

The intergration has worked perfectly for some time and now is not reading all the data all the time with these errors in the log:

Traceback (most recent call last):

I found another post regarding same error, #114 involved this so i did what that post said. I now have to wait if the error returns.

I still have problems that not all values update everytime, sometimes there are a few hours between updates.
How can i see if there is an issue between my meter and the inverter or the inverter and this intergration?

I also have this error after turning debug logging on.

Entity sensor.solaredgemodbus_m1_imported_kwh from integration solaredge_modbus has state class total_increasing, but its state is not strictly increasing. Triggered by state 252.982 (254.402) with last_updated set to 2023-08-30T19:50:18.861421+00:00. Please report it to the custom integration author.

raise ValueError(f"Value {value} failed validation ({comparison}{against})")
ValueError: Value 0 failed validation (>0)

the integration is trying to validate the "m1 exported" value.
The sensor value should be greater than 0 -> but the inverter is sending a 0 value, therefore, the validation failed.

THe problem here is, that if we would validate for > = 0 - the integration would allow the zero value, and then the integration will fail when the inverter is sending a value greater zero, because it would just add the new value to the previous one, causing issues with the energy dashboard and statistics.

MAYBE a solution to this would be, not to write this into the logs... at least, when this behave is expected.

the second error indicates, that the inverter has sent a smaller value for the imported_kwh sensor, than earlier... which should not happen, based on the fact, that this sensor is continously increasing
