Last Update date : Jul 25. 2024

There are a couple of solutions you can try if your Samsung TV appears as offline in the SmartThings app after it has been added to the app. For example, you can check the power cord connection and network connection, and then perform a diagnostic test using SmartThings.

Check the power cord connection

Note: TVs older than 2019 may be displayed as offline when turned off, depending on the network connection method, and cannot be turned on with the SmartThings app. In this case, please turn on the TV with the remote control.

If the TV is not connected to a power outlet, it may appear as offline in the SmartThings app. Additionally, if a TV registered in the SmartThings app is not used for more than one month, it may also appear as offline in the SmartThings app.

1 Disconnect the TV’s power cord and then reconnect it.

3 To check the status, open the SmartThings app, and then navigate to and select the location with your TV. The TV’s current status will be displayed on its card.

Check the network connection

You can check the network connection using the TV’s Settings menu. If your TV is not connected to a network, it may appear as offline in the SmartThings app.

1 On your TV, navigate to Settings, then select All Settings, and then select Connection.

2 Select Network, and then select Network Status.

Note: If there is no Network Reset menu, please reset your network settings.

4 Then, try connecting to a network. To do so, navigate back to the Network settings menu, then select Open Network Settings, and then select Wireless.

6 If the issue persists after resetting the network, please turn your Wi-Fi router off and then turn it on again.

Enable Power On with Mobile

You can also check if the “Power On with Mobile” setting has been enabled on your TV. If this setting is disabled, you will not be able to turn on your TV using the SmartThings app.

2 Select Network, and then select Expert Settings.
