Scenes, scripts and buttons

Tiles that do one thing when you tap them.

On the tile: the icon and the name, with when it last ran as the second line: "Last 14:05", "Yesterday 9:15 PM" or "Never run". A script shows Running… and its colour while it runs.

Tap runs the scene, runs the script or presses the button. Helper buttons (input buttons) work the same.

On a bigger tile: an Activate or Run key on the tile. A full-page scene is one big button, nice for "Good night" by the bed.

To run something that is not a scene or script, put any entity on a tile and set On tap to Perform action: every action Home Assistant offers for it, with its fields.
