As geek-chic as it is to be able to control lights and such from your phone... Am I the only one who would rather just pick up a dedicated remote control with physical buttons?
Automation isn't just about controlling a device through a remote app on your phone though, and most people seem to be missing the real point of home automation.
The killer part of home automation is scheduling, controlling a device through a schedule, or controlling unrelated devices to create an outcome.
For instance, I like my sofa lamp to come on at certain times, I like bedroom side lamps to come on at certain times. I like having a tone of lighting in the house, not oppressive overhead lighting, just accent lights in the house, especially in the evening. So my system already set up does exactly that. Turns lights on an off to a schedule.
You can then link unrelated devices together, so if a window sensor is detected as open, and the ac kicks on, then I get a text telling me which window or door is open. In fact, I believe I can prevent heating/cooling coming on if something is detected as open.
The door and window sensors also act as an alarm. The sensors also have thermometers built in so when the feature is unlocked I can track temperates around the house.
The other thing that is coming, and I'm buying into late this year are remote controlled air vents. I can now run a standard hvac system as a zoned system, simply monitor the temperate in each room, and hopefully the hub will start to direct air only to rooms that need it. I can also start running a spare room at a slightly higher temperature, eg unoccupied guest room.
Another thing that can be added, are the use of scheduled blinds, and with any luck soon, temperature controlled blinds. Why kick in the ac if you can lower a blind for a bit? Again, run ceiling fans without kicking in the ac for a short time. Hmm, 3000W ac system or 600W by multiple fans for a short time.
