High-end toilet can be hijacked by anyone with an Android phone
I'm sure you could find several ideas in here.
Family believes their toilet is possessed - the lid flaps whenever someone enters the room, mimicking speech, and the toilet whispers "Feed me!"
A number of technophiles have been robbed. The MO is pretty similar in all cases - the home owner was locked into the bathroom while the crooks entered the home and stole the loot.
