Look out, Nest. Microsoft is coming at you with its own Cortana-powered thermostat, and it's super fancy looking.

Microsoft has announced it partnered with Johnson Controls on a thermostat called GLAS. The company previewed the upcoming device in a YouTube video, sort of how it first introduced that Cortana-powered Harman Kardon speaker earlier this year. GLAS is made by Johnson Controls, which makes thermostats, but it runs the Windows 10 IoT Core operating system and will offer Cortana voice services.

From the teaser video, we can see that GLAS features a touchscreen display, which you can use to adjust the room temperature, look up your energy usage, check air quality, and view calendar information, among other things. And because it has Cortana - it's actually one of the first thermostats to offer Microsoft's assistant - you can use your voice to control the temperature, too.

Microsoft has said in the past that we can expect Cortana to arrive in everything from speakers to toasters, so GLAS shouldn't be too much of a surprise. The sleek-looking device is equipped with enough to tech to determine whether you're in the room, and it can continuously monitor both indoor and outdoor air quality - all while saving energy. We're just not sure if this is a consumer device.

Microsoft pitched the device as being powered by its Azure cloud services, and the video offers up good use cases for businesses. We also don't know complete specs or pricing at this time. We've contacted Microsoft for more details and will let you know soon.
