This seems to be similar to an idea I had a while back about using bluetooth, RFID, and/or NFC for home automation that was truly automated as in you walk up to the house, maybe enter password on your phone and the door unlocks, as you enter rooms the lights come on if the room is too dark, and if you star watching some TV or a movie or streaming some video or listening to music it would follow you around the house. Granted this would require you to keep your phone with you but I think it would be a good setup. I just never got around to trying to implement anything like that. Google's idea is a lot more widespread and I would love to see some standard interface for IoT like that so the consumer side is completely standardized. It does seem like something I read before about IoT devices basically pushing their own app or web interface rather than someone having to separately install an app on their phone or tablet to use the IoT device.
