Being away from the house, in the past, one would leave a light on to simulate a presence in the house to promote security.  Can we do the same when hackers can see all messaging from the Internet of Things in a house?  Can we record the wifi signaling, then play it back to act like we are leaving a light on in the house?

I'm sure I read somewhere that programmers are thinking about artificial activity generators. It seems to be triggered by the observation that you don't need to hack, just observe wifi activity in a street!

Remote controlled guns in the house should do the job - you could then shoot the burglars while thousands of miles away on holiday. The system could doubtless be hacked from the outside if it isn't well designed and someone could use it to shoot you in your own home, but the guns could use face recognition to work out who's a legitimate target in your house and they would refuse to shoot anyone who isn't. The only controlls that could be hacked are the ones for aiming and shooting, but the rest of the software would run in a closed system, and this would refuse to respond to instructions to shoot or even to aim at non-legitimate targets.
