"Siri, 78 degrees." Almost a year after Apple debuted HomeKit as a part of iOS 8, you can finally control a thermostat using nothing but the Siri virtual assistant on your Apple gadgets.
You can now buy the Ecobee3 at an Apple Store near you. It's a pretty standard smart thermostat that can tell if anyone is home and adjust your home temperature automatically. And, of course, it works with Siri.
A separate version of the Ecobee3 is already on sale, but this new version adds HomeKit support, which means it can be controlled by Siri.
The Ecobee3 will cost you $249. If you want to add more coverage in your home, you'll have to purchase a pack of two additional sensors for $79.
