Tizen 4 WebApp Power Control

Hi everyone,

right now I’m struggling to keep the TV (Tizen 4.0) in the web application on for an infinite period. Every power option given through the menu (e.g power control and eco solution) has been disabled. But as soon as the web app has been launched, the TV automatically switches the “Standby Control” to automatic. I suspect this is the reason the TV goes black after an unspecified period.
I’ve been already through the documentation, the power control API is not available.

Any help would be really appreciated
