I still see this as a scam product. Modern whole house AC, is already "smart". And the people themselves are what is costing them money.
With energy costs soaring, the average American, has to buck up, and learn to cope with summer heat, instead of fleeing from it. We'll be complaining about the cold soon enough. No need to live it in advance.
The cooler you keep your home, the more dramatic the heat is when you have to deal with it. That's where the savings should be, turn the frakkin' air down yourself. You really don't need a new toy to do it for you. In fact, the money you piss away for a "Sensibo", would probaly pay most of your electric bill for the hottest month of the year.
Today's society is truly bizarre, with dependence on smart phone apps for just about every insignificant taskl. Some fool writes an app for something a ten year old should be able to figure out for them self, and it makes the eleven o'clock news as a "breakthrough".
I'm not a luddite, and I'm fully aware of the many ways the computer and internet enrich our daily lives. But, I really enjoy playing the guitar, because there isn't an app for it. And I really don't mind picking up that big, heavy, remote control, and setting my AC all by myself.
Besides, I sincerely doubt that this device can save someone who is already energy conscious, 40%. That sounds like a number someone pulled out of their a**, to use while begging for money.
Although, they could probably sell a boatload of this junk on QVC, to the witless and unsuspecting.
