I use both Do and SmartThings widgets on my apple watch. If I’m understanding the question, for this issue they work about the same, but you can have more choices with the SmartThings app.
You don’t get a toggle, but you can set up one Hello Home Action for each switch state. Add those HHA’s to the SmartThings apple watch app.
- Wrist turn
- “Hey, Siri. Open SmartThings.”
You will now see one button options for each hha you added to the watch app.
Admittedly it can get cluttered if you have too many of them, but that’s true of any watch app.
edited to add it’s a little more complicated to set up, but as @mbhforum points out in the next post if you set up a virtual momentary switch and tie the real switch to that and set the virtual switch up inside a Hello
Home action then you can have the watch widget act as a toggle, so you only need one HHA widget for each device (not each state).
