i own a powerwall in the UK as as we move into winter i am fed up with waking up in the morning to see that the powerwall has not charged overnight.
I have been through support with this already and am told that the algorithm needs to "learn my system". Well i'm sorry but this just doesn't cut it.
Why on earth can't i just tell my powerwall to charge up to a certain level every night on my cheap rate electricity because this is what i need to be able to do. And, frankly, this is what i thought i was getting.
There's no way on earth someone can write an algorithm that can predict my energy usage properly. Even if you tie the system into the local weather forecasts i live in a coastal region where the forecasts are frequently wrong and even if they were right, it's still not good enough.
I have an electrical heating system (air source heat pump) and i need to ensure that my battery is charged adequately, every night, so that the following day i maximise the usage of my low cost electricity.
And what happens if i'm away for a few days, or a holiday, does the algorithm learn that "hey, this guy's not using much power, let's not charge up at all!". Whereas the reality is that ifi had the ability to define when and by how much the powerwall charged up i could have the system ready and waiting for me upon my return. And vice versa, I can tell the system not to charge at night when i'm away up to the day before where it can charge from the mains electricity.
I ask that you give us, your customers, the ability to do this please. Give us the choice - if people are happy with the algorithm then fine, leave the box checked - call it "automatic learning" or something. But for goodness sake stop trying to be so clever because it just doesn't work for people like me, where i live.
