When I first saw the LG's add of connected appliance, I think it's a hook to consumers to drive them either buy their smartphone if they own LG appliance or to buy their appliance if they own LG smartphone. I still believe that. Nonetheless, i can't rule out the potential of connected appliance. It might be able to tell you that you don't know or already forget - like expired food in the fridge.
Duane,I might suggest setting a timer on your smart "whatever" or just on the stove and have it go off when the washer or the dryer should be finishing. That is a low tech but effective means to smarten up your wash duties..
I think that these electronified (I avoided the term "smart") appliances have become "glamor goods." It's another place that early adopters can venture into - another place people can go to "one up" their friends and neighbors.
Beyond that, I'm not sure anyone really knows how much these new devices will change our lives. We may eventually find out that no one really gets added utility out of a connected refrigerator, but that everyone will find the need to own a connected coffee maker. I think we'll find uses we never thought possible.
I, personally do see the utility in a connected washer / dryer. Mine are in a location that I can't readily hear. I often get busy and forget about the wash machine until the clothes have set so long that they need another wash cycle. A text message from the washer could get me up there in time to prevent that and my drier could contact me in time to get the clothes out before they wrinkle.
One could probably come up with a practical use for putting connectivity into just about anything. How about a lowly garden hose? If the hose is left out pressurized on a hot day, it can burst. If it's left left out with water in it during freezing weather, the same could happen. That's a perfect place for an IP connected sensor, once the cost gets low enough.
Actually, having a smartphone interface to a washer or dryer would be really, really nice in an apartment complex or college dorm.
Before walking down three flights of stairs with a heavy hamper filled with dirty clothes, you could check if a washer is available (and even reserve it if the software is really done right). Then it could text you when it is done.
I'm guessing that this isn't what they are doing with the technology, though. It is a shame.
