The WMR300 driver initializes differently starting with v3.7.0. It's possible this broke something. You could try reverting to the old v3.6.2 driver <https://raw.githubusercontent.com/weewx/weewx/v3.6.2/bin/weewx/drivers/wmr300.py> and see if that has an affect.
If you can successfully run weewx on a different computer and/or a different kernel, that would certainly suggest that it is an OS/kernel problem and not a problem with your WMR300 hardware or driver. -tk On Wed, Aug 9, 2017 at 12:59 PM, mot23 mot23 <motmotmo...@gmail.com> wrote: > Thanks for your fast response. > > In the first place, i was thinking about a hardware problem.
