The Cortana-powered GLAS thermostat isn’t as smart as it looks

The GLAS smart thermostat is missing some key features.

Stunning looks ; Large, easy-to-read display ; Support for Cortana, Alexa, and Google Assistant ; Indoor air quality measurement

High cost ; No remote sensor support ; Slow app and frustrating usability issues

Johnson Controls GLAS Review

Finishing close to the top of the group, the GLAS is a solid thermostat, but couldn't quite topple our top recommendations. It has a particularly sleek and...

We were very excited about the prospects of this thermostat and ended up coming away disappointed. This device did quite well overall, but its excessively premium price doesn't quite mess with its second or third tier performance, precluding us from...
