Not nearly complicated enough. Why not interior cameras (infrared?) that watch for signs of water encroachment/flooding or a certain % of the floor area to be a temperature that implies its water. > all that's required is that the valve be able to actuate after N+ years of disuse, which is actually a tall order. Too true. Regular tests and preventative maintenance tend not to happen in too many households. I too am guilty of this, I would say that I find the seal in the shut-off valve for toilets to be dried and leaky a majority of the time I've gone to turn off the water to replace components inside the tank.
