Report generation for Multiple MiOS Controllers

Hi,

Me and my other 7 friends have setup the MiOS controller and few sensors like motion,d/w and few others
I am planning for report generation for the activities occurred (Conditions ) and send that report for each one of them for daily,weekly,monthly etc…by collecting the data at one location. i.e. all the sensors have to send the data to one location.
Let me know what is the best way to Achieve and how can i implement , so can you guys share any documents that might be useful as its very urgent requirement.
I can also call if required.

With regards,
Vikram
