New installation, interceptor not getting any packets, workarounds?

[jeff....@gmail.com]

Hi all,

I've been running weewx 3.9.2/sqlite/python 2.7 on my OpenBSD based router with interceptor configured to sniff traffic going to wunderground.  That all worked just fine for several years.

When I decided it was time to upgrade to weewx 4 (4.10.2) I decided to move everything to an Ubuntu 20.04 OdroidN2 in my lan so sniffing, while not out of the question, would not be as easy as listening.  I also wanted to move to python3 and use mysql as the database.

I installed weewx and its requirements from apt as detailed in the docs.  I added weewx-interceptor using wee_extension and the latest interceptor zip file downloaded from github.

My weather station is a Tycon PWS 3000WC and can upload data in the ecowitt format so I used WSView on my phone to set that up to push data to the odroidn2 on port 8001.  Configured interceptor in listen mode on port 8001, and fired up weewx using systemctl.

All interceptor ever reports is an empty queue.   I can see data coming from the Tycon with tcpdump but interceptor just doesn't. 

I redirected the PWS to send its data to the firewall instead and wrote a small python3 program to run on the firewall that captures the data from the Tycon with nc and inserts it directly in the mysql database running on the odroidn2.

On the odroidn2 I set up a cron job to run every minute to run wee_reports and rsync everything up to my web server.

That works sort of okay  but I'm missing a lot of the functionality of weewx:  no generated data unless I run wee_database --calc-missing, no sending weather data off to places like windy.com and I'm sure there's a lot more.

Given that I can insert data from the PWS directly into mysql how can I then trigger all of the other magic that used to happen when ever interceptor parsed a line of data from the weather station?

Or, probably even better, if anyone has a fix for interceptor that would be great.  Tried it in standalone mode with python 2.7.18. and python 3.8.10 and the results are the same:  nothing.

Thanks for reading!
