EcoFlow Delta-2 MAX - reading device via API

The EcoFlow Delta-2 MAX has an Android application that can monitor and handle the generator.

It can show the battery charge and the instant load/discharge, enable/disable outputs, etc.

Hover one thing is missing : create and show a graph reporting the loading/discharge of the battery, to see for example how much the solar panel contribute to the charge and similar info.
