Looking for Time of Flight (VL53 ToF sensor) product

My project: Due to having 3 boys in the house and powder room, one of them tends to leave the toilet seat down while standing. After watching NetWorkChuck video of HomeAssistant dealing with is kids leaving the toilet seat up and the door open, I got on the quest.

What I need is to know when the toilet seat is down and someone is standing. When this occurs, I could set a light to change color to alert them to wipe the seat. Now for me to know whom did this and could be a suspect of leaving the seat wet, when the door opens, a camera would then take a picture of the suspect. No camera would be in the bathroom.

My thought is using a door sensor to know if the seat is down, same for the door when it is opened. Camera shouldn’t be a big deal either. My search for a sensor which I found on here, is the Time of Flight - VL53. However, I’m hoping there is a product so it wouldn’t be something I have to build.

Does anyone know of such a product?

Thanks!
