Hi Tom  

Many thanks for the prompt reply. I should have mentioned that I upgraded 
to v.5.0.1 early today, that made no difference. I've just set 'debug = 1' 
and restarted. The "weewx" log looks exactly the same (no additional info). 
Therefore, I haven't repeated it. I'm finding the only log I can see is 
when using:

*sudo journalctl -u weewx -f*

If I try the log I used to use on v.4 (i.e. sudo tail -f /var/log/syslog) 
it just says 'No such file or directory'. Ditto if I replace syslog with 
messages.

Here is the log without specifically specifying 'weewx' (not sure if this 
is helpful):

I don't use DHCP - I have a static IP address assigned to the Pi and am 
using the LAN port, connected to a gigabit ethernet switch. I also prefer 
IPv4.

I should point out that I have a very basic knowledge of Linux, hence my 
posting to the group.

Thanks
Neil
