Energy usage cost breakdown

Energy
#1

Hello,

I have an Emporia Vue that reads the meter consumption by minute, day, and month. I also have several plug with energy consumption meter. How can I have the plug, the Tesla charger and other be sub costs of the entire house consumption?

As you can see the Energy dashboards adds up all the meters together and result is obviously wrong.

Thanks

If you are going to add separate loads like that you will have to create a template sensor to replace the Whole House sensor with: Whole House minus the extra loads you want to add.

Makes sense. Do you have a template I can copy or have as an example?
