Apple Widget & Watch - No Options under Settings

Yes, the official SmartThings widgets are only associated with routines.

If you are in the US, you have some additional third-party options.

You can use IFTTT do buttons. This is a free service.

If you have iOS, you can buy a $9 third-party app called smartrules which is both a rules engine and has widgets. I like this one a lot.

If you have android, you can buy a third-party app called sharptools. Not a rules engine, but does have widgets. Also very nice.
