Is there a way to turn LG webOS TV screen off?

Configuration
32

I‘ve just made a script in HA with:


alias: LG WebOS Screen Off - OLED48A
sequence:
  - service: webostv.command
    target:
      entity_id: media_player.oled_48a19
    data:
      command: com.webos.service.tvpower/power/turnOffScreen
mode: single

And it just works. This is so awesome with Alexa for a sleep command, like listen to a YouTube video, screen off and tv off in 10 minutes.

I have 3 LG OLEDs but only tested it on my 48A1.
