Is there any way the Official Tesla Energy App by @Diederik could be updated to allow control of my Powerwall?

One key thing I’d like to do is to control the backup reserve %.

My use case, is that when my electricity cost is cheap, then set my backup reserve to 100% to force my powerwall to charge.

Currently it’s only possible to read data, not write?
