REST API to get online/offline device status

I have been using the REST API to get information about various devices at my home (API | SmartThings Developers)… But I’m not able to find a way to get the status of the device if it is offline or online. I have tried all the Devices GET methods. I can clearly see the online/offline status via the Graph.API site (SmartThings. Add a little smartness to your things.) so there is clearly some data available to show it. Can anyone confirm what call / property will show the offline/online status?

Thanks… That solved it.
