Input configuration for battery_discharge to show total household consumption

I don’t understand the question. In the context of emonCMS, a “Feed” is the data that has been conditioned and manipulated by the processing on the “Inputs” page, and it’s where and how the data is stored. So all your history is in the Feed.

Your data comes from the emonTx instantly - there’s no storage on the emonTx at all - and it’s labelled at the emonTx with a NodeID. When the data arrives in the emonPi, it’s received by emonHub, checked and passed into emonCMS and appears as an Input, now labelled with the name it picked up in emonHub.
