Getting ObserverIp working with python3

[Bill Eaton]

I'm upgrading my desktop/server to Ubuntu 20.04/Python3. My old installation of WeeWx was running on Python2.7. On Python 2.7, I was able to get Matt Walls ObserverIp driver working.

I hacked up the ObserverIp driver fixing all of the things that wouldn't work in Python 3 until all of the errors went away. I gave up when I got the driver running on it's own, but WeeWx was logging some kind of dict rain gauge error.

Now I'm working on the Interceptor driver in listen mode. It runs in Python3 with no errors. But I don't seem to be getting any data either. I'm not 100% clear how it's supposed to work. I telnetted into the bridge and configured it to point to the static address on my desktop/server computer(setdsthn <hostname/address>). By default the bridge wants to talk to port 5000, so I put port 5000 in the weewx.conf file.

The interceptor.py driver runs by itself without errors. And WeeWx starts without errors, but there are a bunch of messages

DEBUG user.interceptor: empty queue

Has anyone had any success with Interceptor in Python3?
