It would seem that performing a connection with

Code:

minicom --baudrate 19200 --device /dev/ttyUSB0

and typing some stuff such as TEST, LOOP etc...
somehow helps getting past the "unable to wake-up console" issue.

I can then get this (notice the "TypeError: format requires a mapping" in the end):

Code:

wee_config_device --info
Using configuration file /etc/weewx/weewx.conf

Also from this it would seem that it's failing while starting to make sense of the loop data:

I know zero about Python myself I am afraid.
