iOS 14 and Big Sur widgets have a few restrictions:
- They can’t live-update; they update more like watch complications.
- There’s multiple sizes: 2x2, 4x2, 4x4. The smallest is a single tap target, the larger more.
- They’re likely going to have to be native UI, e.g. no Lovelace cards.
Here’s a few ideas:
- Actions, like the current today widget. Single for 2x2, multiple for the larger.
- Single-sensor, perhaps with some kind of history graph.
- Template text, image, like the watch complications.
