Hi @javalin, you can use curl command to turn off the light, like so:
curl -L -X POST 'https://api.smartthings.com/v1/devices/<device_id>/commands' \
-H 'Authorization: Bearer <token>' \
-H 'Content-Type: application/json' \
--data-raw '{
"commands": [
{
"component": "main",
"capability": "execute",
"command": "execute",
"arguments": [
"mode/vs/0",
{
"x.com.samsung.da.options":[
"Light_On"
]
}
]
}
]
}'
Ironically, as Ronaldo mentioned above,
Light_On = display off
Light_Off = display on
