You can still use the Apple Watch. If you get Chowmain's TCP/IP driver, you can send programming actions to URLS. Such as
http://192.68.1.100:49486/GoodNight/
Now when you enter this URL into a web browser, the programming action set to GoodNight (or whatever you call it) will start. On your iPhone, you can use Shortcuts to fire the URL.
Use the Get contents of URL Shortcut from the Shortcuts App. When you do that, you will have a new Shortcut which is called GoodNight. You can add multiple shortcuts and even trigger them using voice commands.
This is all possible on OS3
