Blackscreen parameter not working

[MephistoJB]

Hi everyone, I don´t know why, but I can´t get the blackscreen parameter working. as far as i understood, with my config below the screensaver should kick in after 1 minute (which is working) and the screen should be black after 10 minutes (which is not working. Am I doing something wrong or is this a bug.

I use the newest ha and haos version.

Here is my config

wallpanel:
  enabled: true
  debug: false

This should be working.
Can you please try a minimal config, like:

wallpanel:
  enabled: true
  idle_time: 5
  black_screen_after_time: 10

Sorry for the late answer, but I wasn´t lazy. I tryed to narrow down the problem as the minimal config worked on my side. It seems, that this problem (also with the minimal config) appears only with my ios Devices. Could this be a problem with mobile safari?
