I installed Weewx 5.1 on a RPI 2 and made a BYOWS station. It worked, but I screwed up installing updates and shutdown the RPI, so my SD was skrewed. I made a new installation, but no having trouble to get Weewx with BYOWS driver working. BYOWS scripts work, Weewx installing works (works fine with simulator. But when I install BYOWS driver and set the BYOWS as default in weewx.conf I get this error:
