Last x hour average


Last week I installed Emoncms on a Raspberry pi and I have a Arduino Uno counting the pulses. This energy monitor is the 4th I test in our house. I have tested one ready made system (Efergy) that I did not like and two home-made systems. The last system was a scratch-built Picaxe based system that worked quite well, but the limitations of the Picaxe (strange interrupt handling, performance and occasional re-boots) made me want to try OpenEnergyMonitor. So far I have been impressed with the system.

On both my home-made systems I implemented a meter that showed the average energy consumption for the last 2 hours. This meter was according to my opinion the most useful to get a quick overview of the energy consumption. 

Is it possible to build a "Last x hour average" meter on the emoncms?
