Yes. The log portion above is copied "as is" from weewx.log and I didn't 
touch anything before or after.

No, records are beeing generated every 5 mins. But since the connection to 
the console was interrupted, there was no data available hence no records 
being generated in the affected time window.

No connection - no communication. It is a 868MHz USB dongle which connects 
the Raspi to the console OTA. Y

No, I didn't, I didn't touch anything. Connection was regained without 
resynch.

It is running as intendend for over four years now with > 99,9% data 
completeness every 5 mins. I observed connection losses like this maybe 
once or twice before and backfilled the missing data as described above. 
I'd expect weewx to backfill data after connection loss and connection 
regain without any interaction. But something in the database prevents 
weewx from getting the missing data from the console. It acts like there is 
no data, When you restore the database to a point before the connection 
loss happened, weewx reads console data from the affected time windows 
without any problem.
