It's only a partial report this month. My Netatmo mysteriously stopped reporting on December 15. The power and wi-fi were still on as I could see the webcams and the luftpump, but no weather reports, frustratingly.
The good news is that Olle and Annika stopped by yesterday and found that the power plug had somehow become loose! They plugged it back in and all is well again, so I will be able to share most all of January's weather observations.
