Car charging

This charging session, or the last one: its energy (counting up), what it cost and its average price. Under it, the prices of today and tomorrow as bars, with the hours the car charged bracketed and the cheapest hours of the coming night banded. A note says how much of the session fell in cheap hours. Below that, the last sessions as a list with their energy, cost and average price in its colour. The header shows this month’s total.

Sessions are worked out from your charger’s energy readings, which Energy settings record. Costs use the price of each quarter hour the car charged in. The tile only shows what happened: it never starts charging. Small tiles keep the session.
