hello every body,
I am come back on the forum; I just upgraded my weewx from 3.9.2 with skin Belchertown to weewx 4.1.1; I followed the doc.
after upgrade , weewx works well in simulator mode; after I modified my file weewx.conf with my specifications, restart and weewx doesn't work.
After more researches, I done update with "sudo pip3 install RPi.bme280"
now it is good, good job TOM
