since I upgraded ubuntu 16.04 to 18.04 my WH1080 weather station is 
unreachable.
I did a reset of the station, powered it off (no batteries) and reconnected 
it - same output.

I attached the weewx.debug file with my configuration.

The station is connected to a banana-PI. I installed weewx with the 
packages from ubuntu 18.04.

I can't find the error - would be great if anyone could help me, I hate to 
downgrade a system (especially if I don't know if it will fix the problem!) 
;-)

Thank you
Manfred
