If your KS8000 is a North American version (begins with UN), you should be able to add it a device using the martketplace Samsund products section (some say the V1 hub wont work with it). For the notifications, the DTH exposes deviceNotifications () in CoRE. It can be found in the Control Any Device area under Notification Devices once it is a thing. You can enter text as a string value that will be displayed on the TV following a trigger event.
