Connection Error message/exception not catched #184

Open legantois opened 1 year ago

legantois commented 1 year ago

i regularly get this error sequence (i removed my IP address in the error messages)

i am connected to the Solar Edge using a Ethernet connection (not wifi)

Could be a better way to treat this use case😀/error ?

these are two different errors!

the first one:

Error: [Connection] ModbusTcpClient(): Connection unexpectedly closed 3.4332275390625e-05 seconds into read of 8 bytes without response from unit before it closed connection

indicates a lost connection to your inverter - which could be caused by a network issue...

the second one:

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

reports, that a sensor (the data_meter_exported) is reporting a 0 which is unexpected. The integration is checking for 0 values on sensor that should not report a zero - like the exported kwh sensor. allowing this zero to be written to the sensor values would cause a major impact on the generated statistics.

This error usually comes up, when the inverter is in (going into) sleep / night mode - according to the time it was logged. Therefore, I am pretty sure, this error can be ignored and a possible solution would be, to not log this occurance.

seems the first error is still poping up. Difficult to think it is caused by a network issue as inverter and HA instance are both wired
