The Vero4K doesn’t sleep during playback of TV or a video file. The screen is black and the LED is red for a short moment but then the Vero4K wakes up again.
To use the standby I have to stop the playback first . This doesn’t work on the following ways: 1. Standby initiated by the TV via CEC and 2. Standby initiated from Kodi over the power menu.
