ISS

The International Space Station circles the Earth in ninety-two minutes and flies over your home several times a day. The app computes those passes ahead of time, for the position of your Homey, and carries them into your Flows. Above all it tells apart the passes you can actually see, which needs three things at once: the station lit by the Sun, your own sky already dark, and enough height to clear the rooftops. A Flow can then switch on an outdoor light or push a notification a few minutes ahead, the notice being adjustable. Nothing requires an account or a key, and the position comes from your hub rather than from typing one in.
