Hey guys. Is there any Android TV app that can trigger auto turn off after set amount of time of not using CC remote control?

We have a projector connected to ChromeCast with Google TV 4k and also a bluetooth speaker connected to CC. Sometimes we fall asleep while watching a movie/show at night and it is just wasting projector lamp hours. What I want is actually a basic TV feature that pops a message on the screen “shutting down in xxx seconds” and gets canceled with any button on CC remote control.

Projector actually has that feature, but then I have to use projectors remote control (trying to get rid of it with smart IR blaster and Home Assistant) to cancel the shutdown and even if it goes off CC is still playing sound from BT speaker. Projector has HDMI CEC settings, but it is not working at all unfortunately.

CC has a feature “Automatically turn off when inactive”, but it never gets to inactive state because Jellyfin will just play a next episode (can be disabled, but would like to keep it) or TiVi mate is just playing until closed manually.

All opinions are welcome, thanks
