I have confirmed and to the best of my knowledge, the station altitude is
set correctly (altitude = 2320 foot).
When I run weewx directly (sudo weewxd weewx.conf) I get the following:
Traceback (most recent call last):
File "/usr/bin/weewxd", line 64, in <module>
weewx.engine.main(options, args)
File "/usr/share/weewx/weewx/engine.py", line 852, in main
sane = os.stat(config_path).st_ctime
OSError: [Errno 2] No such file or directory: '/home/pi/weewx.conf'
I really do not understand what that means. I went and looked at line 64
and 852 but don't know enough to see a problem. I understand the last line
because my config file is at /etc/weewx/weewx.conf. Is there another way
to run it directly?
Once I get past this step, I can try the other suggestions you had.
