@Beuvusiey94 We’re almost there 😉
When you see the screen with the two options The TV-Box turns off automatically / The TV-Box does not turn off you will see that in the banner at the top there is “Deactivation behavior” in blue, but also “Standby state” in white.
One arrow up, one arrow right + ok and you are in the right place to change the sleep behavior config.
