Hi, I have designed a simillar product, which uses ADE7755 to measure energy consumption of one or more appliances. The device will be plugged into wall socket, and appliances will be plugged into the device socket. It will then transmit data via IR link to a reader. You can view it here.

I can deliver the whole hardware project which includes schematic/PCB design, firmware development on arduino UNO (or another customized board) to provide energy data via wifi. But I need more information on this, and bid must be higher.
Or I can provide only the energy metering part (schematic, PCB design, etc...).
Pls PM if you are interested, we will discuss further and I will modify my bid accordingly.
Best regard
