Hey there, @Tinhwee. At this time, Samsung SmartThings is not a supported partner with us on all products you can see their full list of supported Ring products here, which may be why the device is not showing up under your SmartThings app. I have passed on the integration suggestion to the appropriate team, but in the meantime, you can try reaching out to Samsung SmartThings Support to see if they have any suggestions for you on this.
