Hi,
Ok I can try that.
I am running weewx 4.3.0 installed with setup.py.
I have a SDR with weewx SDR driver and a custom extension derived from a
BME280 extension that will inject some extra measures in the measure loop.
Regarding logs, even though I set debug=1, i find only minimal info in
message and no stacktrace whatsoever.
So I run ./bin/weewxd > logfile 2>&1.
Below is the crash log from last night:

the mysql exception may be linked to the mysql instance nightly backup. I
don't remembet having these on the previous nights.
the loginf is not defined (I botched my traces in exception handling),
should have been a print.
;
PISenseWX.py is the fancy name I gave to my extension.
TCS32725.py is the sample python module provided with the pisense for
lightsensor use.
