Just installed Trixie on my Raspberry Pi 3. I created a virtual environment
and installed Python, required software, and WeeWX using PIP. The weather
hardware is from BC Robotics, which has worked beautifully for many years.
I wrote the driver many years ago.
My test app runs fine. I can also run WeeWX manually (i.e., activate my
weeve virtual environment and then run 'weewxd') and it operates just fine.
However, if I start weewx using the command 'sudo systemctl start weewx'
and check the system log it does not start properly. I'm very confused by
the following error in the log:
Oct 08 08:35:08 raspberrypi systemd[1]: Started weewx.service - WeeWX
weather system.
