I put the new version up on my iPad, and am comparing that to my iPhone running the 3.x app. Weirdly I like it, and I usually hate changes. Quick observations on the Powerwall screens:
The default Powerwall screen has a lot more information (like all of the power meters in addition to the charge level). In the animated power graphic on that screen, they swapped the position of the Powerwall and Grid.
The energy graph expresses the breakdown of where energy goes and comes from in kWh instead of % now, which I think is more useful.
I do like being able to see the Powerwall's charge level during the course of the day. I understand that you can't get all four of the meters overlaid at once...personally I always found that confusing so I never did it. But I get where losing it would be disconcerting.
The Impact screen gives you more information about usage during different TOU period.
In general it feels like it takes fewer taps to navigate around the app.
I presume that "Time-Based Control" now maps to "Cost Savings" in the old app? I wonder what happens if you were on "Balanced" before? Thank goodness they got rid of the gratuitous Storm Watch animation in the settings. They went from up/down buttons for e.g. reserve settings to a slider.
On the backup history: The old and new app are actually showing different data! The new app is showing several outages of "a few seconds" that the old app did not. The new app shows the starting and ending times, where the old app did not. The new app seems to show less history. This is weird.
