During the solar smart charging Beta trial we will not have access to any hardware integrations. This means we can't assess the house "base load" or your home battery's charge level. Our algorithm doesn't take this into account. This means that your car's battery will take precedent over other household loads, including your home battery.
From the input we'll get from the Beta trial, we'll know which hardware integrations to prioritise on our roadmap. This means that in future, we'll take into account the load on your home battery. Ultimately this will provide you with a choice of whether to draw on your home battery or not.
