Unable to find WeeWX log messages

[Ben W.]

Hello!
New/noob user and slowly getting everything together. I have weather sensors feeding into an Ecowitt GW1100 hub. Over the past day, I worked on getting WeeWx installed on my RPi 5. I feel I'm almost there, but not quite.

When I run the "weewxd" command, I get results so that tells me the connection is there. It polls/refreshes every 20 seconds. But that is it. That's as far as I can get.

I want to view the data and build a report (I believe you call them skins(?)), but cannot seem to find any of the folders/directories where the data should be.

To find the logs, I run, "sudo grep weewxd /var/log/syslog" or "sudo grep weewxd /var/log/messages" but then a "no such file or directory" is returned.

Any pointers or directing me to the resource that I missed/overlooked would be great!

What I'm using:
Ambient Weather WS-5000 weather station
Ecowitt GW1100 hub
RPi 5 8 GB Headless (no monitor/ command line only)
2TB HDD drive (that I want to use to store the WeeWx data - to do later)

Thanks!

Take a look at the wiki guide View logs. 

You didn't say what kind of operating system you are using, but odds are your system is using journald, so pay particular attention to that section.

Thank you, Tom! 

That was the right section and I am seeing some critical errors now that I should investigate:

The only USB device is the HDD external drive connected to the RPi. The weather station, Ecowitt GW1100 and the RPi are on the same home network.

Thanks
