Since I only want to display a few PV data, I decided to use the two database fields "signal1" and "signal2" as storage location for the output data of my two inverters. In principle, this also works, but I do not receive totalized yield data. This means that at the end of the day, I can display the history, but not the daily output.
Another issue is the subsequent import of the stored data into the WeeWX database. I wanted, to have the year 2022 complete, to transfer the data saved as csv to the WeeWX database afterwards using wee_import. I have prepared the csv accordingly and assigned "signal1" and "signal2" to the group group_energy in the units.py file. If I start the import with the parameter "--dry-run" everything is fine. Without "--dry-run" the process also runs without errors, but the data is not included in the database due to a UNIQUE problem. However, I would like to add the PV values to the respective existing data record and not create a new data record. Is there no way to keep the existing record and only save the additional values?
