I am rebuilding my RPi and have copied the weewx.conf and weewx.sdb from my
previous implementation. When I attempt to start weewx it exits beceause
it can't find the serial port. The error message in the log file indicates
that the port is ttyUSAMA0 while the weewx.conf has ttyAMA0. Not sure what
has happened.
FYI the OS version has changed from Buster in my previous implementatio to
Bullseye very recently.
During the OS install I have seen some errors about the locale being
unknown. LC_MESSAGE, LC_ALL and LC_CTYPE. I executed export commands for
each setting them to en_US.UTF-8. No idea why this happened or if it is
related.
I have attached my weewx.conf and a text file with the standard output
created by the command grep weewx /var/log/syslog
An advice would be helpful.
