In addition to the $day($days_ago=1).rain.sum you can also use $yesterday.rain.sum if you just want yesterdays rain
or perhaps you really want to know if it rained while you were asleep and would prefer the last 24 hours in which case you can use the Span function like this $span($hour_delta=24).rain.sum where delta is the number of hours... Since Weewx stores everything in a Database lots of presentations are possible... On Sunday, June 14, 2020 at 5:24:47 PM UTC-6, Jeff A.
