Hello,

We have noticed a discrepancy in the monthly and yearly reports in the FoxESS Cloud.

Monthly Report (Daily Breakdown)
Below is the data from the report for November (by days):

The API also returns the same data for this month:
Endpoint: /op/v0/device/report/query
Parameters: year=2024, month=11, dimension=month
{"errno":0,"msg":"success","result":[{"unit":"kWh","values":[3.8, 8.3, 3.2, 20.9, 6.7, 2.6, 4.1, 5.3, 3.2, 4.4, 3.0, 2.4, 2.4, 1.2, 14.9, 3.6, 6.4, 4.8, 2.6, 4.3, 8.8, 0.2, 0.3, 0.5, 6.3, 1.0, 2.3, 1.9, 9.4, 2.4],"variable":"generation"}]}

Yearly Report
Here is the yearly report:

The yearly report shows 148.6 kWh for November. However, summing up the daily values from the monthly report yields 141.2 kWh.
At the same time, the API returns the correct data for the yearly report:
Endpoint: /op/v0/device/report/query
Parameters: year=2024, dimension=year
{"errno":0,"msg":"success","result":[{"unit":"kWh","values":[61.6, 220.9, 965.2, 1181.1, 2383.0, 2069.7, 1812.3, 1893.5, 1347.9, 670.2, 141.2, 46.5],"variable":"generation"}]}

What is the source of the discrepancy for the number 148.6 kWh displayed in the yearly report for November?

If needed, I can provide the inverter's serial number (SN) in a private message.

Thank you in advance for your assistance!

Best regards,
Alex
