weewx installation failure on Raspberry Pi

[John Mora]

Hello, I am attempting to install weewx on my Raspberry Pi 4 8G. I follow the instructions in the manual: http://weewx.com/docs/debian.htm

I log in to the system using the same user/credentials as when I installed PiHole and Unbound which installed and ran without any issues.

When the weewx installation completes, the service fails to start and there appears to be folders/files missing.

Here is the console output from the installation process, the output of "systemctl status weewx.service" and "journalctl -u weewx"

Any assistance would be awesome. If any other information is needed please ask and also keep in mind I am a bit of a newb at this, meaning "Explain like I am a 5 yesr old"

Thanks in advance.

1. Any particular reason why you're trying to use Python 2 on a Debian 10 system? Normally, the expectation is that Deb 10 (buster) users would be using Python 3.

2. What is the results of

ls -l /usr/share/weewx

3. What is the results of 

ls -l /usr/share/weewx/user

aaaah - he used the python2 instructions, not the python3 instructions.

Might be easier to just delete the package and follow the python3 instructions which will get him the python3 package.

[John Mora]

Thanks for the response. The reason I used the python 2 directions was pure user error.

I retried using the python 3 instructions and was much more successful, although am still getting an error, but it appears that the it can't open a port to connect to the weatherlink live device.

Any direction as to why?

Thanks!

It appears that you are trying to use the WeatherLink iP logger.

Are you sure that's what you want? Most people have serial or USB loggers. The WLIP logger is not made any longer.

Thank you for the response and your patience.

I am using the new WeatherLink Live connected via Ethernet cable directly to my router. I am able to ping the device from the Raspberry Pi and even use the browser to show current conditions via JSON.

It is currently configured and working as expected. It is sending information to weatherlink.com.

[Tom Keffer]

I see. The WLL logger is not a supported logger, so you'll have to install an extension for it. There are several listed on the Wiki.

AHA! Yes, I understand. I just read into the extension for it. I will install the appropriate extension and move forward.
Thank you for your time, it is highly appreciated.
If I run into an issue with the extension and getting it to work, I will start a new thread.

Cheers!
