Happened on this topic by accident, but am very grateful now to be able to say a big THANK YOU to tomho. The app version of Powerwall Companion saved my sanity in the early days of having a Powerwall, on my Android phone of the time the Tesla app didn't load reliably, and was ******* useless when it did.
I could only wish that it had been you that designed the Tesla app, as Powerwall Companion is so much better. That said, the official app does seem to load quicker now, and they have taken some comments on board and made some improvements, such as a "go to a specific date" facility; it seems unbelievable that prior to that one had to scroll through day by day to get back to a specific date, with each page taking up to 15 seconds to load - such an omission.
But how I also wish that you could extend the app to give charging level control to the user. By this I mean an option to "charge to x% tonight", with x being chosen the evening before by the owner of the battery. Although again it is better than it was, the Time Based Control option doesn't always make the right decisions for charging overnight, and only I can know what demands I will make on the battery the next day, such as, say, exceptional use of an oven or an extra washload. And only I can make a reasonably accurate forecast as to how much sunshine there will be. A "charge to x% tonight" would be such an improvement.
I know it can be done using Raspbery Pis but it's completely beyond me, and I would be delighted if someone such as tomho could devise something that idiots like me could use. Sadly I suspect it's impossible.....
