I am still trying to fix the March 1, 2 hole (where the system will have to look two months back for data vice one month. Currently, it will cause a very incomplete summary (only using Jan and March data). Now that the basic algorithm is smooth, I can change to accommodate the special case. Stay tuned.
Monthly Summary Stats. The bulbs (and plugs?) with energy monitor can provide monthly consumption summaries for the previous year by month. Is anyone interested in a SmartApp that will gather this data on the 1st of each month and SMS to your phone? It would send two messages - current year summary and previous year summary.
