Access to 'All Time kWh/d'? - For use in Home Assistant

I see in the My Electric app that there is an ‘All Time kWh/d’ value.
Is it possible to access (maybe an API) this value so I can bring it into Home Assistant?

If I cannot get this value directly, then is the next best option to add the ‘Max daily value’ process to my input and then capture that in Home Assistant to then calculate the mean? Or is this possibly a better option anyway?
