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.
