Here is what I do. Someone please correct any errors.
stop weewx sudo /etc/init.d/weewx stop
remove power to Van2
restart and set time on Van2
check time on Pi is correct or reboot and wait until it is correct.
restart weewx sudo /etc/init.d/weewx start
watch syslog for Pi d/l from Van2 sudo tail -f /var/log/syslog
sometimes the data has to be cleared from Van2 ( search doc)
I recommend using a power pack with "pass through charging"
for a cheap UPS and a SSD for the Pi. Those cards all die
at some point and a cheap drive will save a lot of time and
frustration. A hardware realtime clock would have saved you
all this trouble. After an interuption the Pi and Van2 will
not have the same time and will be unable to d/l.

So I'm a complete newbie. A friend did the initial setup on my
Raspberry Pi and it worked great for several years. Uploaded my Davis
Vantage 2 wx station to Weather Underground flawlessly.
Power blinked and went off for several hours last week. Since then
... nada. I have tried to restart weewx but I know zippo. I don't
know enough to follow some of the threads here and make any sense of
any of it.
My friend emailed me this:
Try sudo /etc/init.d/weewx start
I did try that using my VNC Viewer to connect to the Pi and Weewx said
it started. But it's not uploading. So ...? I don't even know where
to begin. Any and all ideas are very welcome. Thanks!
