I don’t know what smartthings plans to do about it officially, but you can take a look at the Ifttt Apple Watch app and see if it gives you sufficient functionality.
I’m developing an Apple Watch SmartThings app. This allows you to execute scenes and control devices from your wrist. I am looking for a small group of beta testers. You must have an Apple Watch with WatchOS 7 (or higher) paired to an iPhone with iOS 14 (or higher). Right now this app is for US only. If you are interested in testing please email me at info@jwerfel.com
Grab a cheap Raspberry Pi (a Zero W will do) and install the Homebridge image. After a bit of configuration, you will then be able to use any of several HomeKit apps to control your SmartThings devices. You will be able to automate with iOS automation, and Siri to control devices and scenes. The Apple Watch has built-in HomeKit, and there is at least one app for scenes.
Here’s the real hoot: Homebridge on the Pi usually works more quickly than the new SmartThings app. (At least for me, running this setup ar two locations.)
Can this app be made to be used/downloaded without an iPhone? I have my kid setup with an Apple watch family plan and really want him to be able to open and close the garage so he can ride his bike to school. The way the watch is set up, there is no iPhone paired with it and that prevents me from downloading any apps that require an iPhone. It seems like I could just copy the smartthings token to the watch manually if the app allowed it.
Sorry I didn’t see this question earlier. As you noted JSmartWatch currently is a WatchOS app that uses an iPhone app for configuration. This was done because there are not a lot of good ways of entering something like an API key on an Apple Watch. Using the on watch input functions works but it is tedious. All of the functionality is on the watch and after the configuration is done the iPhone app is not required (although it provides support).
I have not looked into the Apple Watch family plan so I wasn’t aware it didn’t allow Watch/Phone apps. I will look into what it would take to allow the watch app to work without the iPhone app. I’m not sure if it will be possible at this point but I’ll look into it.
