Bad off-grid data?

[travwill]

Having a hard time figuring out these bad estimates and data that show up in an outage or when off grid.

1. When off grid I show solar production which is bad since it’s 10:20pm hehe.
2. On the usage estimate, does that change real time or is it using historical data? E.g. in this pic if I have 2 powerwalls on this gateway, that’s about 26kW, so I’d expect at 3.3kW use, I’d have 7.8 hours left of energy, not 9.4. But also it often underestimated too.

Confused on this for sure, any thoughts or experience is appreciated.

Good chance your CTs are installed wrong. Send this picture to Tesla in a chat session.

I think usage is done historically (at least in Time Based Control) but if your CTs are wrong, its moot data.
