"""An off light and an off binary sensor look off, as in Home Assistant (app 0.2.62 / firmware 0.2.53).

Home Assistant's own light icon is a bulb that is crossed out while off (`mdi:lightbulb-off`), and every entity that is
off is grey. An icon of its own, or one chosen in ESP Screens, stays the same and turns grey, as in Home Assistant.
