I haven't tried it, but form the docs, http://www.weewx.com/docs/customizing.htm#general_aggregation_periods, I would think something like this would work. If you were using the Seasons skin I would add it to "current.inc". <tr> <td class="label">$obs.label.Rainfall Yesterday</td> <td class="data">$$day($days_ago=1).rain.sum</td> </tr>
