does your router allow the server (RPi) to connect to other devices,
especially to the GW1000, resp. the GW1000 to connect to the RPi ?
Routers often restrict the access by default.
Ports 45000, 46000 TCP/UDP need to be open for weewx to communicate with
the GW1000 and vice versa.

I'm moving my WeeWx back to the right Pi, but with up-to-date Pi OS,
WeeWx and GW1000 driver. Versions are:
WeeWX 4.5.1
GW1000 0.4.1
Raspbian 5.10.63-v7+
I have another Pi working quite happily picking up data via the GW1000
driver, so I don't think there's a problem there.
I've following the instructions at GIT to install it using
wee_extension but when I try to test it I get:
$ PYTHONPATH=/home/weewx/bin python -m user.gw1000 --test-driver
Using configuration file /home/weewx/weewx.conf
Unable to connect to device: Failed to detect device IP address and/or
port after 3 attempts
So I've run this:
$ PYTHONPATH=/home/weewx/bin python -m user.gw1000 --sensors --debug=3
And this is in /var/log/debug:

No idea what the problem is. I have a feeling I might have had this
problem previously and documented it, but I've managed to lose that
document - if it ever existed. :(
