Reimagine your home with the clearly smart thermostat.


Elegant design for a smart home.


Adapts to your schedule.

Designed with arrival anticipation and occupancy detection, GLAS® intuitively monitors your schedule so when you’re home, you’re comfortable. GLAS isn’t just elegant. It’s always working.

Breathe clean air.

The GLAS smart thermostat monitors and reports indoor and outdoor air quality so you can manage and be aware of the air you breathe. Indoors, GLAS provides real-time reporting on humidity, total volatile organic compound (tVOC), and equivalent carbon dioxide (eCO2) levels. Outdoors, GLAS provides real-time air quality reporting on allergens, tree pollen, grass pollen, ragweed pollen, and the air pollution index (API). It even communicates ozone levels and the UV index. Plus, you can schedule reminders to change the filter and for maintenance visits. Just a few less things to keep track of.

Getting things set up – your way.

GLAS, powered by Windows 10 IoT Core, gets to know you and your home right out of the box. It’s easy to set a 7-day temperature schedule on the thermostat or from your phone or tablet. Home, sleep and away settings ensure an even more personalized space, while its delightfully easy-to-read display provides clear information. No more squinting at cryptic settings. Most importantly, it knows when you’re home and when you’re not so it can adjust the temperature – and your comfort – accordingly.

Control your smart home devices with Cortana® intelligent assistant.

Your GLAS powered smart home can now respond to the sounds of your voice. With a simple command, Cortana can adjust the termperature, dim the lights, and more.
