Johnson Controls' GLAS Smart Thermostat costs $319. That's 70 bucks more than the and . Given that, the GLAS had better be pretty spectacular to compete. 

In some respects, it is.

It's immediately clear you're paying extra for the GLAS' neat-looking see-through OLED touchscreen and its built-in speaker. The Johnson Controls thermostat also monitors the indoor air quality, ArtemiaGlasGarten so you can see, at a glance, if you should circulate your HVAC system's fan. That's a really nice touch. 



The app and the OLED display are responsive and simple to navigate, too, making for a good overall user experience.
