By connecting your TV to your smart doorbell, you’ll be able to see who’s at your door without taking your eyes off the big game, or leaving the sofa.
Open the SmartThings app and add your smart doorbell as a device if you've not already. You can do this by clicking add (+), then "Device", and following the instructions on the screen.
Once you’ve added the doorbell, it’ll ask you to sign into the account for your doorbell provider.
Find the SmartThings app on your TV and sign in.
Finally, go to the settings on your SmartThings app on your TV, and pick when you want the doorbell video to show up. You can choose for this to happen when someone rings the doorbell, or when motion is detected. Whichever you decide on, the TV will then be able to show you when someone’s at your door.
