Setup a Gen 2 for Sub-Metering

The Gen 2 Vue is a great way to keep track of energy usage in sub metering situations. Some localities have specific laws related to sub-metering, especially in rental situations. First thing to do is to check your local regulations.

Depending on how your usage is broken up between users, you can use the data to separate usage per user and bill accordingly. You can have multiple devices on a single account and monitor/ bill user based on the usage from all/ a portion of a devices monitored usage:

Tenants on a separate meter: Install a Gen 2 Vue in a panel where the tenant is responsible for all of the usage in that panel. The total usage for that device will be the figure for which the tenant can be billed off of.

Tenants on a shared meter: Install a Gen 2 Vue in the shared panel. Install 50A CTs on every circuit the tenant is responsible for. The sum of these 50A sensors will be the total usage the tenant is responsible for.

How to Bill Users: 

Fixed Rate Users: If you have a fixed rate plan, you can enter that rate in the Cost/Rate Settings. Then, when you set the Unit of Measurement to Currency, your devices kW/kWh usage will be displayed with your fixed rate applied in Currency. You can use this figure to bill a user.

Time Of Use Rate Users: If your TOU rate is in the NREL database, you can enter that rate in the Cost/Rate Settings.  Set your devices Location if you haven't already and select your TOU plan from the dropdown. Then when you set the Unit of Measurement to Currency, your devices kW/kWh usage will be displayed with your TOU rate applied in Currency. You can use this figure to bill a user.
