Multi Metering scenario

Hi,

I am having this scenario related to Device Management.

There is a premise (office premises preferably) where the client has:-

  1. LeD lights with Single Phase connection.

  2. AC with 3 phase connection

The client will be getting a month end bill with 0.5% Discount for LeD connection & INR 2/unit additional for 3 phase AC connection.

Pls advise from the DM point of view how to map this in the system.

  1. Do we need to install 2 different Meters for single & 3 phase connections

  2. Do we need to do FULL installations for the both.

Thanks,

Aditya
