White screensaver

[drbartek]

I have the same symptoms on an old Samsung N8010 + LineageOS 16 like issue 208.
The tablet turns white from time to time and needs to be woken up usually 'back' is enough but sometimes it needs a reboot.

my settings:

wallpanel:
enabled: true
enabled_on_tabs: []
hide_toolbar: true
hide_toolbar_action_icons: false
hide_sidebar: true
fullscreen: true
idle_time: 0
fade_in_time: 0
crossfade_time: 0
display_time: 0
keep_screen_on_time: 0
black_screen_after_time: 0
control_reactivation_time: 0
screensaver_stop_navigation_path: ''
screensaver_entity: 'off'

Once an hour tries to send a command via MQTT and still appears a white screensaver not responsive to touch.
{
"wake": true,
"wakeTime": 15,
"clearCache": true,
"relaunch": true,
"volume": 100,
"reload": true
}

Could I ask for help how to disable this white screensaver.
Thanks

You can try to use keep_screen_on_time: 86400 to keep the screen from dimming or locking.

I think I might also be running to the same issue although I have a slightly different setup

My setup: Raspberry Pi with touch display and a docker container running chrome browser
(https://github.com/Tomcuzz/MQTT-Pi-Display)

Checking the logs around the time the white screen comes up shows the following:

This seems to be related to authentication of Hass due to timeout of the refresh token.

@drbartek Did you find a solution to this in the end?
ALso how are you authentication your dashboard? Are you using trusted_networks or logging into an account on your dashboard?

I apologize for the delay.
The problem still occurs -> occasionally reboots the device.
I'm logging into an account directly on my dashboard.
