N.B. The values in Settings.php/Settings-weather.php override the built-in settings in other scripts when using the Saratoga template.
Even in ajax-dashboard.php? Hadn't realised that could be used standalone. . .
Sorry for the duff gen, @chief-david
P.S. If this is your new Davis station you probably need
$SITE['DavisVP'] = true; // set to false if not a Davis VP weather station
too. . .
