Re: Private message regarding: [weewx-user] Weewx stopped posting data

[Tom Keffer]

It appears that whatever user you are running weewx as does not have permission to access /dev/ttyUSB0. 

Either use sudo, or change the permissions on /dev/ttyUSB0.

The reboot of the console did nothing. So I stopped weewx and ran the dump and clear memory command.

I restarted weewx and still nothing.

Set debug=1, restart weewx, let it run until it crashes or the first reporting cycle, whichever happens first, post the log.

I have a vantage pro 2 station. My OS is Linux Mint. I had changed the batteries in the console. When I did so, I also unplugged the power to it. Upon replacing the batteries and rebooting the console, weewx not longer posts anything to Index HTML or NOAA. I tried removing power including batteries and rebooting again but to no avail. 

Next, I purged weewx and then reinstalled. Still nothing. Yet, when I run weewxd in terminal it posts the loops there with all my station data.

It dumps directly to the database. See the documentation on wee_device --dump.

Running those commands using sudo solved the issue. Once I did that, weewx started posting data again. Question - where does wee_device --dump put those files? Many thanks for your help!
