Hi Luc, Ok I took a look at the weewx web interface and it does look like it's receiving data, which is good! I had not checked before because I thought the driver was not working. It's just this that fails:
pi@wxpi:~ $ sudo PYTHONPATH=/usr/share/weewx python3 /usr/share/weewx/user/rtldavis.py --cmd="/home/pi/work/bin/rtldavis --tf US" Weewx itself seems fine though, no errors in the logs. Not a big deal for me, but if you would like to continue troubleshooting the driver I am happy to help. Unrelated (?) question. I don't seem to be getting any pressure data. Station is a Vantage Pro 2. Maybe the loop period needs to be longer? Happy to attach some data if that is helpful.
