When adding energy values from a service providers API they are usually retrospective for the previous day but when adding them to HA shows them as the current day. Adding the ability to add a timestamp when adding an energy sensor reading would allow accurate recording of energy use per day.
Do you mean energy injecting history? If so, integrations can already do that. Some do even.
Injecting History is a far more succinct way of saying what I wanted yes, must be an issue with the Octopus Energy integration specifically then which pulls yesterday’s usage from cloud.
