Glas Smart Thermostat

Monitors air quality.

GLAS provides you with the information you need to help make your home healthier. The smart thermostat monitors humidity, tVOC and eCO2 levels indoors. It even reports pollen and air quality outdoors – especially helpful for asthma or allergy sufferers.

What’s behind GLAS?

Johnson Controls invented the room thermostat
135 years ago. With your family’s health and energy
savings in mind, we reinvented it with GLAS. The
smart thermostat can help create an efficient and healthy space,
and its clean translucent interface reimagines any space.
