OK, I tried stopping the daemon and running directly. The LOOP data shows
no difference between outTemp and windchill although the console shows a 4
degree difference. I have attached my conf file in case I messed up
something. I see that when the change to support LOOP2 was submitted, a
request was made for testers. Was it ever tested?
On a side note, when I tried running weewx directly without a config file
argument, it would not run, even though my config file is located at
/etc/weewx/weewx.conf. Is that a bug?
Thanks!
