How to meter main Panel with a submeter on a panel downstream

I have a main home on a Main 200a panel.
I have a second smaller home on a 60a panel downstream of the main panel. It is powered by a breaker on main panel.
I have tenants in each home I would like to Bill using encompass.

I was able to hook up a Push3 and omnimeter v.4 to the subpanel to monitor the smaller home and set up online billing via encompass.

basically my setup now is in this order : Main Meter> Main electric panel > omnimeterv.4 > Small home subpanel.

I would like to be able to create a bill using the encompass billing tools for the main home, however I do not have any submeter on the main home.
I would like to subtract the amount owed/energy used on the smaller home from my main electric and gas bills, and bill the tenant in the main home accordingly.

I am able to create separate groups for each home on encompass, but I am not able to set up billing for one of the homes due to no submeter being on it. Is there a way to override this and enter information manually?

Hello, no there is no way to manually enter 3rd party meter data into encompass. In your case you would also want to install a submeter on the main house which excludes the circuit going to the subpanel on the smaller home. That way you could get the meter data from both residences into encompass.

You can do what you are doing now where you are manually subtracting the smaller homes usage from the utility meter and then billing the difference to the main home. This works if the utility meter is accurate, but can sometimes lead to disputes. The best way to avoid disputes is to have 2 submeters (one for the main house and one for the small house) whose combined usage per month should equal the utility meter per month. Im trying to say this from experience rather than in an effort to get you to buy more submeters :lol:

I hope this is the information you were looking for.

Thank you for the response.
How would I set up the 2nd meter to exclude the 1 circuit?

I have about 15 breakers on this main panel.

To meter the main house, you could have an Omnimeter with 2 current transformers. You would pass all of the wires from Line 1 (with the exception of the wires you want to exclude that are going to the small house) through the Line 1 CT and pass all of the wires from Line 2 (with the exception of the wires you want to exclude that are going to the small house) through the Line 2 CT.

Here is an article that describes how you can pass multiple wires from the same phase through a current transformer:
