Just to dredge up this topic again... I was sitting at a course for work yesterday on Information Security and talking about network architecture and the like, so I decided to do a new count on network enabled devices I have at home.
For a 2 person house, my tally comes in at 32.
We have (not exhaustive):
4 x Lifx bulbs,
5 x wemo switches
2 x ipads
2 x iphones
2 x laptops
1 x imac
3 x Apple TV's
1 x TV, Blu-Ray, PVR, PS3, internet/dab radio, etc....
and to monitor all the nonsense, a few IP cams as well!
It might be getting a little out of hand.
