INV;Aggregations;Has unknown data

Q: Some data loggers have a strange message in the log file and sent data: 

{“$ts”:230728071507,”$msg”:”INV;Aggregations;Has invalid data”}, …

A: There is a bug fix available for the aggregations driver, suppressing error log message “Aggregations;Has invalid data”, even, when aggregations are not used.

Upgrade your firmware to a version higher then V4.8 B5.
