I was using the first statement from a previous installation of weewx
running a different version on ubuntu. There was an issue where the
expression wasn't evaluating correctly without first testing to be sure the
value was being passed from the station to weewx. The second, expression.0
is supposed to allow the alarm module to evaluate multiple alarm settings
but doesn't seem to work.
I need to test from the command line. Where would I see the values?
