I have been using Fully Kiosk+ActionTiles+Smartthings for awhile and been happy. Screen would go to sleep after a couple of minutes but motion in front of the camera or sound would wake it up. PIN needed to exit Fully to the app menu screen.
Updated to Android 10 recently. As a result, frequently the screen would not wake up and I had to resort to using the power switch (not easy on a wall mount) or sometimes even needed a reboot. Only current solution according to FK tech support is to have the screen stay on 100% of the time. I am worried about that burning the screen.
So, I have resorted to just using Chrome to display the AT panel. To facilitate ready access, I removed PIN protection on the lock screen so I only have to swipe to restore AT panel when the screen saver comes on. To keep from automatic powering down after extended screen saving, I enabled “developer mode” and enabled “constant on as long as plugged in”. Anyone have a better solution?
