home energy monitoring

I would like to develop a home energy monitoring system able to monitor the total home energy flow (both direction) and appliances (load) energy flow. The system comprises a master unit (PCB) to be installed on a DIN rail in the main home switchboard and a plurality of client units to be installed on the plug of the home loads. The client units and master unit shall communicate via power line. The client units shall be able to connect or disconnect the load on end-user request. The master unit shall be able to connect to external server though the home internet access. The user shall be able to connect to the home energy monitoring through the internet or through the home net. The master unit comprises a SD card for local data storage. The master unit can be configured as client if needed (in case more master units are installed). the winner must: define the EU standards to target select the components and the suppliers design the PCB layout select the manufacturer make a prototype test the prototype and ship to us eventually assist us in certification process make modification in case we fail certification The winner must then cooperate with the software developer team (android, os, chrome, etc). Attached: system overview, master unit overview, client unit overview.
