Maybe I did not get the example? I would not need to get up to turn off the light b/c I can use a trigger like touching something on my night table. But if that something and the light switch are somehow networked, can't I just use my phone and some app to directly turn it off? Same thing with the timer example: isn't my phone already capable of running all sorts of abstractions? Why would I need to borrow the timer function from the tv? Finally, as far as discovering objects and its capabilities, wifi + some sort of IoT protocol should do, right? No need to point a camera, this gadgets will always be broadcasting its API (and ACLs I hope). Sorry, maybe I did not get the product at all.
