Keeping Fully Kiosk dashboard awake

Configuration
1

I mounted a tablet to the wall, showing an HA dashboard via Fully Kiosk.

The design goal is that it goes off (to protect the screen and save a little bit of power) when nobody is around, and turns on when someone is in the vicinity.
To accomplish that, I have an movement sensor nearby, which triggers whenever someone walks past it. An HA automation responds to this event and turns the screen switch of Fully Kiosk to on. In Fully Kiosk, I’ve configured the screen to automatically turn off after two minutes.

This works okay, but it expectedly fails when there’s movement for more than two minutes. The HA automation cannot ‘extend’ the timer of Fully Kiosk. So after 120s, the screen turns off and with the next movement, back on.

Is there an elegant solution to this? Some kind of ‘wake lock’ in Fully Kiosk to trigger instead of the screen switch?

Or should I just disable all screen management in Fully Kiosk and instead implement everything in HA: the ‘on’, the timer and the ‘off’ event?

Fully kiosk has built-in movement feature (via tablet’s camera). It might be a part of paid features, but it’s worthed to buy it.

My motion sensor is working perfectly. The question is how to tell Fully Kiosk to extend the wake time by another x minutes when movement is detected while the screen is already on.

If you want to use your motion sensor you’ll need to disable Fully Kiosk’s screen off function and use your automation to turn it off as well, just as you would a light. At the moment you’ve got control split between two devices.

There’s a very economical automation for lights here - it should work for the screen switch as well:

Beside using suggested automation above; another way is with using fully’s motion system as i suggested, it will automatically extend “on time” until camera detects any motion.
