Please make a combined energy graphs to know how much electricity has been consumed in the month within the "whole house". So we don't have to go from device to device summing each bill calculation. 
 

also it would be nice to be able to select in wich day our bill starts and ends, because my company ends every 12 of the month, so I have to check each 11 to sum it up to last month and remove those 12 days from the last bill.
